This charger is designed specifically to pair with the Ultra Long Life Battery, but it can also charge any kind of Lead-Acid battery and has a selector switch for Gel/Wet batteries. It can also be adjusted to charge Lithium-Ion batteries.
An AC charger allows batteries to safely and effectively draw power from an AC power source in order to charge the battery. This can be useful in starting a battery that has been too deeply discharged, or quickly topping off a battery ahead of an oncoming storm which threatens to knock out power. This device is essential for using batteries as back-up or emergency power sources without any personal power generators.
This charger can be left connected indefinitely without causing any harm to any battery and includes watchdog and security features in case of any failure to charge correctly.
