Braille 12v 6a lithium charger/maintainer charges at a reasonably quick 6 amps and is designed to maintain & keep Braille lithium batteries fully charged when not in use or sitting for long periods of time. In the case that a Braille lithium battery is every fully discharged (10 volts is considered 0% state of charge on a 12v lithium battery), this charger does have a "pre-charge/revival mode" that will do a slow "pulse charge" as long as the battery has at least 2 volts (to know that it is connected to a battery) and will slowly bring it back up to 10 volts before charging at the standard 6 amp rate back up to full. This updated charger now comes with an SAE quick disconnect end along with a ring terminal harness and standard battery clamps for more charging solutions in a variety of vehicles, bikes, etc. (Power cord included, but not pictured) Replacement glass fuse: F10AL250V Model: 1236L DC Output DC output voltage, nominal: 14.2V DC output current, maximum: 6A Output fuse: F10AL250V or T10AL250V (5 x 20 mm) Automatic multi-rate charging, CC/CV profile with Pre-charge @1.8a.
