I've just started using one of these for about a week now and i'm impressed by it. Since the weather started getting cold the battery voltage would drop to 12.2 volts after not starting the car for about a week and a half. Now with this connected and plugged in the lowest the voltage drops to is 12.97 and then it starts charging and goes to 13.82 and repeats this cycle automatically. For $18.00 and the peace of mind knowing the battery will be maintained at full charge at all times and will extend the life of the battery it is a great deal. It only charges at a rate of 1/2 amp so no worries of it over charging when plugged in for long periods.

BATTERY BUTLER® - 12-Volt Automatic Battery Storage Charger & Maintainer
This Battery Butler® is the least expensive method to retain a full battery charge on any 12-volt system in a car or truck in storage without overcharging. Delivers a safe, low amp charge that extends the life of your battery.
It’s compact, small enough that you could actually leave it under the hood when not in use in most applications.
It is designed for long-term use. You can leave it connected to a 12-volt battery indefinitely. This unit provides a safe, 1/2 amp regulated charge. It prevents the self-discharge of the battery, while extending the life of rechargeable 12-volt batteries rated from 5 to 125 amp-hours. It does so by providing a safe, low amperage regulated charge. Even trickle chargers are not designed for long term use. It maintains the battery at peak charge so it’s ready when you need it.
The red light indicates power from the wall outlet. The green light indicates the battery is being charged properly. Once the battery is charged, it will automatically shut off, then turn on again as the battery level drops.
There are 2 adapters included. Select either the battery clip adapter or the ring terminal adapter.
Charger unit measures only 1-1/2″ square by 3″ deep. This integrated power supply includes automatic charging, monitoring, and switching circuitry.
Specifications:
Input Voltage: 110 volts AC, 60 Hz
Output Voltage: 14 volts DC, 300-400ma
For use on 12-volt batteries only
The Battery Butler® automatic battery storage charger is designed for the maintenance of wet or gel-cell batteries that are stored or used periodically in such vehicles as cars, trucks, motorcycles, boats, motor homes, ATVs snowmobiles, personal watercrafts, lawn tractors, farm equipment, etc. - anything that uses a 12-volt system.
