⚡️ WirthCo 20062 Battery Doctor Black CEC Certified Smart Battery Charger & Maintainer, 12V, 500mA Review

When I tried this battery maintainer, I was impressed with how easy and reliable it was to maintain my car battery. It kept my battery charged and ready to go, even after sitting unused for weeks. The LED indicator also made it easy to know when my battery was fully charged. The only downside is that it doesn't work with all types of batteries but for those it's compatible with, it works like a charm.

Works as described. The LED indicates whether the battery is charging or not, full or almost full. It's easy and good to keep a battery for a car that doesn't use much. I use it to save my weekend van battery. When the battery is low, it takes a long time to charge since it only has 0.5 amps.

Easy battery maintenance. This is the same device sold under a different name by Menards and others. I have one that charges the alternator battery and the other that charges my sister's battery in her spare car. Pays for itself in months if your car starts when you need it. This can recharge a dead battery, but it takes a few days.
