Schumacher SEM-1562A 1.5 Amp Automotive Battery Maintainer and Charger:
Specs:
Unique automatic battery charger maintains both 6 and 12 volt batteries keeping them at full charge using float-mode monitoring. Perfect for charging small batteries. Great for maintaining small and large batteries kept in storage – motorcycles, classic cars, RVs, boats • 1.5 amp charger and maintainer • LEDs indicate: Charging, Charged and Trouble • Automatically switches from Full Charge to Float-Mode Monitoring • Quick-Disconnect Harness – Snap either connector into place in seconds – Use the 50 amp clamps or permanently attach the ring connectors…great for hard-to-reach motorcycle batteries • Reverse-hookup protection
I'm using the Battery Tender Plus and am using it outside and leaving it plugged in all winter. I really like the temperature compensation to ensure optimum charge voltage according to ambient temperature feature, the 4-step charging program, the safe operations that are built into it and that it comes with a 10 year warranty.
The Battery Tender Plus 12-volt/1.25-amp Battery Charger is the convenient solution to the challenge of keeping 12-volt vehicle batteries optimally powered when not in use. It is able to charge any lead-acid battery--including standard and sealed AGM and Gel Cell battery types and is also designed to be easy to use in difficult spaces, to utilize a 4-step charging program and safely function in a fully automatic mode.

Safe, 4-step Battery Charging
The Battery Tender Plus 12-volt/1.25-amp Battery Charger is much more than a trickle charger. Powered by BTP microprocessor technology, it has a "brain". Utilizing a 4-step charging program (initialization, bulk charge, absorption mode and float mode), it allows you to simply connect the charger to a battery, either in or out of a vehicle, and forget about it until you are ready to put the battery to work. Like all Battery Tender chargers, at the end of the regular charger cycle the it automatically switches its output voltage to a safe, storage or float level that eliminates the need to worry about the damaging effects of overcharging, and the resulting need to check on the condition of the battery. If or when the battery voltage drops too far under load, output power resumes and the charging cycle begins again. The unit also features sparkproof connectors, short circuit and reverse polarity protection, an easy to understand charging status LED indicator, a quick connect harness for use in hard to reach areas and almost no current draw from batteries connected to.
Key Features:
- Perfect for all lead-acid, flooded or sealed maintenance free batteries (AGM and gel cell).
