The ultimate pocket tester for on-vehicle battery performance & alternator voltage testing with either 12V lead-acid or 12.8V LiFePO4 starter battery – Easy troubleshooting from cranking to charging!

  • For vehicles fitted with 12V AGM, GEL and STD lead-acid or 12.8V LFP / LiFePO4 starter battery.
  • As easy as 1-2-3, connect to battery, check state of charge, start engine tester displays cranking voltage and vehicle charge voltage simultaneously – 15 sec is all you need!
  • Display cranking volts down to 6V and charge voltage range up to 15V – Check weak battery or overcharging!
  • Easy to use! Connect with the included clips to the battery or connect to an installed SAE battery lead.

Easy to use! Connect clips to the battery or connect to an installed SAE battery lead, then:

  • Check battery charge level. A low battery cranks (starts engine) poorly.
  • Start engine. OptiMate TEST records and indicates (for 20 sec) the lowest start volts.
  • With engine running, verify charging voltage from alternator and voltage regulator.

TIP: Low charge voltage causes poor battery performance. Too high charge voltage causes excessive gassing and will eventually damage a lead-acid battery. Too high charge voltage is FATAL for a LiFePO4 starter battery!

Great filter and easy installation
Style: BE-159 1-Pack, Style: BE-159 1-Pack
For my 2016 Hyundai Sonata Hybrid Limited. I cannot believe I paid so much more for a brand-name filter that does the same thing as this one. It is made of the same material as the dealer one I took out. Very easy to install, cant believe I paid for this to be done in the past with oil changes. Requires no tools and did not get dirty at all. No mechanical skills needed, especially if you run into trouble and can use YouTube. PROS - great quality, cannot tell that it is after-market - very professionally made, not irregularities seen - excellent fit in position, no adjustment needed - very easy to install, cannot believe I paid to have this done in the past - no mechanical skills needed to install - great price compared to what big name productions want for the same thing - cannot tell the difference in air quality between this and the dealer filter I took out - removes outside odor completely - did not require tools are getting dirty CONS - None

Fits perfect and works as designed. Flows like OEM and looks well made.
Style: BE-553B 1-Pack
This filter is very comparable to the stock filter. Fits the BMW G20 just like OEM. I would not say it is two times "heavier" as advertised on the box, but it is very comparable to stock. It's the same weight and similar construction. BMW has a very robust cabin filter. This will be my go to. I did purchase another aftermarket cabin filter that fit well, but was thin, flimsy and had a bad chemical odor. This one is fine and airflow is the same as OEM. I change them every year or so. I don't worry too much about longevity with cabin filters personally.

Good quality but it was slightly longer than original and needed modification.
Style: BE-182 1-Pack
Bought this cabin filter for a 2023 Acura TLX. While the filter seems to be made of quality material, it was just a little too long (about a 1/16 of an inch, so I had to trim it to make it fit so the cover would fit snug. I was able to do that without compromising the filter itself. But this might be an issue for some people

Installation was a breeze, fir nicely and the air in teh car now smells fresh and clean. The old filter has developed a musty smell so this new one is great. Had it replaced in under 3 minutes.

Fits perfectly for my 2017 VW Passat
Style: BE-373 1-Pack, Style: BE-373 1-Pack
Bought this for a fraction of the cost. An auto shop wanted to charge me $72.99 for a filter so I bought this Spearhead brand cabin filter and its the perfect size and its just as sturdy as the previous one the dealership had in the car. Not sure yet how the airflow is or if anything different as I have not driven in the car since it was replaced, but it appears to be a very high quality cabin filter for my car at a great price.
