Don't get stuck with a dead battery.

The ANCEL BM300 is a handy little 12V battery tester that checks not just the battery, but also your charging and cranking systems.

It's compatible with Android and iOS devices, so you can see the results on your phone.

It tests all the common battery types: AGM, gel, flooded, and lead-acid.
It can even detect bad cells.
It's small—about 5x4 inches—and weighs just 0.18 pounds.
The voltage is 12V, and it's brand new in the box.
ANCEL includes a 1-year warranty.

Whether you're a mechanic or just a car owner who likes to stay on top of maintenance, this tool is super useful.

It plugs in and gives you a quick, clear readout on your battery's health.

No more guessing if your battery is weak or if it's the alternator.
Simple, effective, and affordable.
