Century 12V 37Ah Gel Deep Cycle Battery: Premium Gel Deep Cycle Technology for Demanding Applications

The Century 12V 37Ah Gel Deep Cycle Battery is engineered to deliver reliable, long-lasting energy storage for a wide range of demanding applications. Built with Century’s industry-leading Gel electrolyte technology, this battery suspends the electrolyte in a thick, immobilised gel state. This advanced internal structure not only eliminates the risk of leaks and spills but also provides exceptional protection against plate damage caused by vibration and deep discharge cycles.

Designed to withstand the rigours of the Australian climate, this deep cycle battery outperforms traditional lead-acid equivalents in cycle life and reliability. It is the ideal power solution for mobility scooters, electric wheelchairs, marine vessels, and recreational vehicles (RVs) where consistent power delivery and safety are non-negotiable.

Superior Deep Cycle Performance and Longevity

Unlike standard car batteries designed for short bursts of power, the Century 12V 37Ah Gel Deep Cycle Battery is constructed with heavy-duty lead-calcium grids and high-density active material. This design allows the battery to withstand repeated deep discharge and recharge cycles without significant degradation. The gel formulation prevents acid stratification—a common killer of flooded batteries—ensuring consistent performance throughout the battery's lifespan.

Whether you require steady power for a trolling motor or reliable energy for medical mobility equipment, this battery offers superior deep discharge recovery. Delivering up to 400A discharge current (5 seconds), this compact unit provides reliable bursts of power when needed.

Maintenance-Free and Vibration Resistant

One of the standout features of the Century 12V 37Ah Gel Deep Cycle Battery is its completely maintenance-free operation. The valve-regulated, sealed design means there is no need to check fluid levels or top up with water, making it perfect for installation in hard-to-access areas. Furthermore, the immobilised gel acts as a shock absorber for the internal plates, offering excellent vibration resistance. This makes it particularly suitable for mobile applications like camper trailers and boats where travel over rough terrain or choppy water is common.

Storage and Efficiency

Efficiency is key in off-grid and backup systems. This battery features a low internal resistance and a self-discharge rate of less than 3% per month at 25°C, allowing it to sit in storage for extended periods with minimal power loss. However, to maintain optimal health, it is recommended to charge the battery at least once every six months if stored inactive.

Important Installation Advice

While the Century 12V 37Ah Gel Deep Cycle Battery is built tough, it is designed for deep cycle applications rather than engine starting in high-heat environments. Fuel, oil, and extreme under-bonnet temperatures can damage the casing and internal components. Therefore, installation under the bonnet of a vehicle is not recommended and will void the manufacturer's warranty. It is best suited for dedicated battery boxes, cabins, or external compartments away from direct engine heat.

Key Features

  • Gel Electrolyte Technology: Immobilised gel prevents spills and enhances cycle life
  • Deep Discharge Capability: Designed to recover effectively from deep states of discharge
  • Maintenance-Free: Sealed valve-regulated construction requires no water top-up
  • High Vibration Resistance: Protects internal components in mobile and marine environments
  • Low Self-Discharge: Retains charge longer during storage (approx. 3% loss per month)
  • Wide Operating Range: Discharges effectively between -40°C and 60°C
  • Safety Considerations: Flame arrestor and central venting for enhanced safety

Power Your Adventures with Confidence

The Century 12V 37Ah Gel Deep Cycle Battery is a robust energy solution that combines safety, longevity, and high-efficiency performance. Ensure your equipment runs longer and more reliably with Century’s trusted deep cycle technology.

Junk. Save your time!
Size: C20, Size: C20
Okay, so I thought I did good research on this. I saved up for this purchase excited since we had just finished installing new floors through our entire house. As soon as the installers left, I broke out my new vacuum, downloaded the app, followed the instructions and did the required upgrade to the vacuum. Once it started to do it's first mapping route, the app immediately said network slow. The vacuum would pull out from the base about a foot and just spin, then return to the base and start drying the completelt unused mop heads. I've tried taking it to my friends house and using another person's wifi, deleting the app and reseting the vacuum multiple times, tried repositioning a few feet from our router, tried running it through my ipad instead, everything including having comcast come out and check our network. Mind you, our TVs, alexa, ans any other devices in our house work just fine on our network. Eufy App would always say network slow and not even go further than a foot from the base. Obviously something is wrong with the vacuum, not my wifi. Finally contacted customer support. First one in the chats brilliant solution was to try ro run the vacuum through Hotspot. Seemed ridiculous, but I tried. Once again, app said network slow. He then said he can't help me and that my chat log is being sent to their "engineering department". Waited 1-2 days for their "engineering department" to email me. They wanted proof of purchase, serial number, and a video of what's wrong with it. Submitted it and was told it'd be another 1-2 days while their "engineers" review my issue. Woke up to an email this morning from their engineers and their suggestion after everything I've told them was to "try restarting it". Did they even read my messages of everything I've tried to do to be able to just use and keep my vacuum? Try hot spot and restarting it is their advice from their "engineering department" after days of waiting for a solution? Returning this. Customer service is a joke if they ship you a faulty vacuum. Now I have to wait 30 days for a refund and then go buy a different brand. Waste of my time and left me disappointed over something I was excited about. Update - Eufy contacted me and offered a refund. Said to reply "Full refund" if i wanted one. I did. That was the day after the origjnal post, and they never responded or gave me a refund. Customer support sent me a replacement. Worked beautifully after I skipped the firmware update. It did an automatic software update yesterday, and it got stuck at 15%. When I woke up this morning, it's stuck at 13%. Once again our network is fine and stable, there's something wrong with their updates. Even customer service after doing their "analysis" of the returned original vacuum said that their "engineers" had diagnosed the problem as a hardware/software issue. So, now I gotta box up another bulky item and return it. Hopefully by the new year I'm finally given a refund! Save your time!

Efficient, Sleek, and Hands-Free Cleaning for Smaller Spaces
Size: C20, Size: C20
I live in an 800 sqft condo with mostly hardwood floors and a few small rugs, and the Eufy Omni C20 has proven to be a great fit for my space. Here’s a breakdown of my experience with the vacuum: 1. Ease of Use The Omni C20 is incredibly easy to set up. After plugging it in and filling the water tank, I was good to go. The water tank is very user-friendly, with a convenient handle and a well-sealed cover that prevents leaks, which is a common issue with some competitor models. The ambient light under the water tank adds a cool visual touch, making the vacuum feel a bit more premium. 2. Lidar/Proximity Sensor Upgrade The lidar and proximity sensors on this model are a major improvement over other robots I’ve used. Coming from the Eufy X8 and Dreame D10 Plus, both of which had solid lidar systems, I’ve noticed the Omni C20 maps my apartment much more efficiently. In my previous models, the first mapping session could take 20-30 minutes, and the robots didn’t always distinguish between walls and furniture. The Omni C20, however, only takes about 3 minutes to complete the initial mapping and does a 3D scan, accurately identifying solid walls from furniture like countertops. Very impressive! 3. Sleek Design and Low Profile While the lidar sensor is much improved, what really stands out is the Omni C20’s sleek design. Unlike my previous robots, which had a visible sensor bump on top (think of the lidar sensors on autonomous cars like Waymo), the Omni C20 has a slim, almost Tesla-like profile. The entire body is only about 3 inches tall, allowing it to easily go under tight spaces like couches and cabinets. I’m not sure how Eufy managed to achieve this, but it’s a big plus for anyone with limited clearance. 4. Good Surface Detection and Nice Cleaning Performance with a small trade off The C20 does a great job of differentiating between surfaces. It switches seamlessly between mopping and vacuuming when it detects a change in floor type, even when it comes to something as small as a door mat. Its cleaning performance is impressive, though it’s not the fastest robot out there. On average, it takes about 1 minute per 10 sqft for a combined mop-vacuum cleaning session. For comparison, my Dreame D10 does the job almost twice as fast. However, the C20 delivers superior cleaning results and even goes back to wash the mop during the cleaning cycle, which contributes to the longer duration but is a great feature. I’m happy with the trade-off since the C20 offers a more thorough clean. 5. Ok Battery Life and Long Charging One of the few drawbacks I’ve noticed is the battery life. It’s not the best in its class. On average, the C20 uses about 60% of its battery to clean my entire 800 sqft apartment. By contrast, my Dreame D10 only uses about 30% for a similar cleaning. The C20 also has a slower charging time, taking over 3 hours to fully recharge. However, given its smaller profile and ability to clean tighter spaces, I’m okay with the trade-off. 6. Mop Drying Noise Another small concern is that the robot produces a low, constant noise for a few hours while it dries the mop after cleaning. While it doesn’t use hot air drying like some competitors, it’s a more energy-efficient approach. This isn’t a major issue for me since it’s part of the self-sustaining, hands-free cleaning process. I’m happy to let it do its job and dry, charge, and clean itself without any intervention from me. Conclusion Overall, the Eufy Omni C20 offers a fantastic hands-free experience with impressive cleaning performance and thoughtful design. While it’s not the fastest in terms of cleaning time or battery life, the superior mapping, sleek profile, and thorough cleaning make it well worth the investment. If you have a smaller space, like a studio or a 1-3 bedroom condo, this is a great robot vacuum to consider. However, if you have a larger home and need longer battery life, you might want to explore other options, especially bigger ones. For me, it’s been a great fit, and I’m very happy with the results.

If you think you need a robot, you probably do
Size: C20
Bought this to clean up after my dad since he spills food on the floor multiple times a day. So my impressions so far, both good and bad: #1 Fairly easy to set up, it makes you use an app of course, but the app is pretty nice. Mine wanted bluetooth and of course WiFi activated, but I think you can run it from your phone from another location without bluetooth. #2 After setting it up in the dock and charging, I think it's best to let it map your whole house. I moved a bunch of stuff while it was mapping, but then I later wanted to add another room, so I had to have it map the whole house again. This wasn't really a problem since the robot maps a lot of areas pretty quickly. However, you can't edit maps in a way you might think you could, instead you just have to let it make a new map. The robot will latch onto power cords etc. while it is vacuuming/mapping the house for the first times. I'm impressed at how well the robot maps. #3 The mopping is kind of mid-range with some really good and not so good elements so far. So the clean water and dirty water tanks are great. The 2 mop swirls are really good. The robot struggles a lot to get much mopping done because it wets/cleans the mop at the station, then takes the damp mop to mop a small spot, then has to return to clean the mops again. This is fine, but then the mop station stopped working and gives a cleaning tray error over and over. There seems to be no way to inspect the cleaning station in order to try to remove obstructions, I already checked the bottom tray, top containers, bottom of the robot, and looked for any way to access potential obstructions, so this may be the defeating flaw, but I will try a few more times. Overall I really like the robot mop and I definitely want one that works well, so we'll see. First update: I watched a youtube video showing where the water suction tube is on the dock station, so that helped a lot to position the flexible tube so it will suck water up correctly.

Made cleaning so much less stressful!
Size: C20
Love, love, LOVE! As a multi-pet home, I cannot stress how much less stressful cleaning is! Two cats, and a German Shepard, I run this once a day for the vacuum and every other for the mop. vacuum has multiple settings based on needs. For myself I run it on standard (level 2/4) to pick up the loose hair that has fallen. The vacuum is also great for litter messes, though I do usually run it on turbo (level 3/4) for the better suction with litter. I was amazed the first time I watched the vacuum run over a large tuft of Shepard hair with ease! It has made cleaning so much easier The mop aspect is mediocre, it does help don't get me wrong. But even on the high (level 2/2) it is meant as a maintenance rather than a full clean. Meaning some dirt, dander, dust it will do fine with. But sticky spills... unlikely. The parts are super easy to change. The vacuum bag slides in and out, whereas the mop pads are similar to a Velcro and peel off easily when wanted. As far as hair; it does well at sweeping it up. Though the first few runs I had to clean the roller each session due to the amount of hair. The ends of the roller brush come off easily, twist/pull and this allows you to remove any hair twisted around the piece. Super easy to clean and put back together! Additionally, the only issue I have with the vacuum is that it likes to run over the cat toys that I didn't even know we still had! Ha! It will generally stop and wait for assistance if it runs one over or gets stuck which is as simple as removing the toy and pressing the power button again. Set up was easy as well with a step-by-step instruction through the app. Unboxing to use only took at most 10 minutes! I have noticed others comment on the price... I got this on sale for $350. Retail among other sellers is $700. I think for the price I purchased this is definitely worth the cost! The initial vacuum bag was just replaced after 3 weeks, and it could have lasted probably another full week before demanding I change it. Though this will vary based on home to home. The vacuum can be noisy at time, though much less than I expected after watching some video reviews. The loudest part of it is the vacuum running into furniture though. I think the mapping feature works well but given we have pets and are often moving things around our vacuum is often repositioning and re-mapping the rooms as needed, it does this automatically (after bumping into things).

Replacement unit working better than the original
Size: C20, Size: C20
EDIT: Replacement unit working better than the original! The seller offered a full refund, and since I had another vacuum of there's (different model) that didn't have any of the same problems, I asked for a replacement instead. The other vacuum has been great! Replacement was in hand shortly after returning the defective unit. None of the same issues as the original. It's not like this is the greatest robot vacuum ever invented, but for the price this is a rock solid vacuum and mop that's now been keeping our floor spotless for more than 2 months! I feel bad for the old vacuum... :-( I've worked in manufacturing before, so I know you'll have a dud unit every so often. Unfortunately, I received one of those. Fortunately, Eufy seems to be a company that stands by it's products. I'm very pleased with the quality of their customer service and of the replacement unit. ORIGINAL: No longer runs: Laser sensor malfunction after just 5 months. This product was maybe 3 out of 5 to begin with. It didn't do a very good job at avoiding cables or animals. Nor did it do a good job at getting corners, but it did run when scheduled. After just 5 months, it rolls out from the station and stops. I get a notification that the Laser sensor may be blocked. There's nothing blocking the sensor. I've cleaned the lens, and the issue still persists.
