Review on π TOPDON TORNADO4000 4-Amp Fully-Automatic Car Battery Charger, 6V/12V Battery Charging Units & Maintainer with Advanced 10-Steps Charging and 8 Charging Modes, Ideal for Various Battery Types by Matt Heringer
Good for charging, not battery saving.
My battery saver didn't work. Tried with 3 batteries. After using 1 battery, it returned to the test as a good battery. Waited 24 hours, checked again and came back to change the battery!
Pros
- Great for a small home
Cons
- Unreliable
