OptiMate 12V Battery Tester TS-121

This pocket-sized premium tester designed by TecMate is solid, reliable and easy to use. Simply connect the clips to your 12V LiFePO4 battery or connect to an installed SAE battery lead, then:

  1. Check battery charge level. A low battery cranks (starts engine) poorly.
  2. Start engine. The OptiMate TEST unit records and indicates (for 20 sec) the lowest start volts.
  3. 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!

Really happy with the product!
Color: Premium-CF10285
I’ve bought this air filter replacement three times now for my Rav4, and I couldn’t be happier! It fits perfectly, installs easily, and really helps keep the air in my car fresh. I’ve noticed a big difference in air quality since switching to this filter. For the price, it’s an awesome value, and I’ve never had any issues. I’ll definitely keep buying it whenever I need a replacement. Highly recommend it if you want to keep your car’s air clean and fresh!
