The AA Battery Charger and Maintainer is used and approved for use by AA Patrols. It’s an intelligent battery maintainer and charger that is a fantastic solution for most car batteries. The built-in microprocessor will sense the condition of our car’s battery and will control its own regulator, providing just the right current and voltage to suit the correct level of charging.
It features four stages of battery charging. The soft-start stage is where the maintainer will perform an initial battery test to determine the battery’s condition. In the bulk stage, the battery will receive the majority of its charge. Then, in the absorption stage, the charger will drop to its minimum output and slowly charges the battery up the rest of the way to 100 percent. In the final stage, referred to as float mode, the battery will be kept steady at a 100 percent charge. This will keep your battery optimally charged without overcharging and damaging it.

Car Battery Trickle Charger Buying Considerations
When searching for the best trickle charger for your battery, you should consider several factors. Some of these factors include your battery type, wall-socket connectors, and whether you need a slow maintenance charger or a fast-charging device. But for trickle chargers, your primary concerns should be the following.
When you’re looking for a trickle charger, it’s a good idea to know the capacity of the battery you intend to charge. Both the batteries and chargers are marked in amp-hours. You should make sure that your trickle charger has a higher amp-hour value than the battery you’re trying to charge. Most of the high-quality chargers have adjustable ampere rates, however, maintenance chargers should ideally be under 5 amps while a faster charger should be at least 10 amps.
While not entirely a necessity, charge indicators are incredibly handy features. A charge indicator will tell you when the battery is fully charged, which will help to prevent any overcharging that could damage or break your battery. The most advanced charging units will sometimes even have digital displays that will show the progress of the battery’s charge, estimated time until a charge is fully achieved.
The safety features of a trickle charger may be the most important thing to consider when searching for the best kind of trickle charger for your needs. You should look for units that include features such as reverse polarity connection protection, which help to make sure that you don’t accidentally damage your vehicle’s electrical system if you connect the charger to the wrong terminals. You should also look for features such as short-circuit protection, spark-proof technology, overheating protection, and overload protection.
