Voice of Custom:
- My BMW's battery died and couldn't be recharged by the car. The dealership quoted $600 for a new one, but result showed charging it might work.
- This was the deciding factor in whether I should replace my battery or buy a battery charger.
- So far, I'm really happy with the FOXWELL BT100 Battery Analyzer. It's smaller than my work ones, and that's great because it's easier to carry, use, and store.
