  • Plug-and-play compatibility and no memory effect: Designed as a straightforward replacement for the original Dell battery, this 8-cell pack is easy to install with minimal downtime. The Li-Ion chemistry exhibits no memory effect, so you won’t need to fully discharge before recharging. This translates into more practical charging habits and a smoother user experience, allowing you to top up power without worrying about downgrading capacity over time.

  • Power down and prepare: Shut down your laptop completely, unplug the power adapter, and close the screen. If you’re replacing an older battery, move any open files to save your work. Place the laptop on a clean, flat surface to access the battery bay securely.

  • Align and insert the new battery: Take the DENAQ 8-Cell 4400mAh battery and align the connectors with the corresponding terminals in the battery bay. Insert the battery firmly until it sits snugly in place and the securing latch or fastener clicks to lock it.
  • Reconnect and power up: Return the chassis cover, reconnect the power adapter, and press the power button to boot the laptop. If prompted, allow the system to recognize the new battery; it may perform a brief calibration during the first charge cycle.
  • Initial charging and calibration: For best results, charge the battery to full capacity before heavy usage. Avoid prolonged deep discharges during the initial cycles. If your device supports battery calibration, follow the manufacturer’s guidance to optimize capacity readings over time.

Don't waste your money.
Instead of buying one from the local auto store, thought I'd save money and get this. Bad choice. Installed it and it didn't work. Took it to the auto shop to be tested and they said it didn't work. Cheap imitation of the the real thing.

Exceeds performance expectations of OEM fluids
Size: 5 Quart Jug
You know I didn't think it would work as well I've heard all these horror stories but you know what this works better than the factory CVT fluid this stuff is great this is amazing be very careful to get your levels correct that goes without saying with any transmission but once you do that this fluid is amazing I have a better performance than when I had the new transmission I serve my CvT 35 to 40,000 miles I'm using it in a 2018 Mitsubishi outlander base model and I'm also running Yokohama geolander 015s on it. If you worry about tires for you Mitsubishi or any vehicle. I'm going to say you'll call when you lander whether it's a car or crossover or an SUV this tire is amazing it's best all around tire and your rain traction is phenomenal

Good Stuff!! All low speed shudder is gone.
Size: 5 Quart Jug
I have a 2020 Nissan Altima SL 2.5l and Nissan is VERY specific about using ONLY NS3 transmission fluid. There are only a couple NS3 transmission fluid manufacturers...Nissan NS3 (Manufactured by Idemitsu), Idemitsu (a little cheaper than Nissan dealer), Triax, and Mannol (works good too). Seeing as Nissan is still using Jatco CVT transmissions which are known to be very troublesome, and very expensive to replace I wouldn't try any of the so-called "universal" transmission fluids just to save $50 and end up replacing a $6000 transmission. The Triax fluid seems to work very good in my car. I don't feel the shutter that I normally feel when driving slow and need to accelerate. The shudder is completely gone and operating smooth. The old fluid had 50k miles and it was very dirty but didn't smell burnt. I ended up doing 2 - 3 1/2 quart changes with 200 miles between the first and second change. I plan on doing another 3.5/4 quart change every 15k miles since there is no way to completely drain the 7.4 quarts of transmission fluid. The first change, only 3.5 quarts drained from the pan.
