Automotive battery chargers are small and straightforward solutions that are excellent to maintain your vehicle batteries fully powered when not in use. Battery Tender, for example, makes it feasible to charge any lead-acid battery such as standard and sealed AGM and GEL Cell battery types. It is built to be easy to use in small spaces, to use a 4-step charging program and also function safely in a fully automatic mode.
The Battery Tender 12V Battery Charger,for instance, is a lot more than a trickle charger. It has a core processor that uses a 4-step charging program (initialization, bulk charge, absorption mode and float mode).It means that the battery can be connected to a battery, either in or out of a vehicle, and be left alone until you are ready to put the battery to work. At the end of the regular charger cycle it automatically switches its output voltage to a safe, storage or float level.This way there is no need for you to worry about the destructive effects of overcharging hence eliminating the requirement to check on the condition of the battery. When the battery voltage drops too far under load, output power restarts and the charging cycle begins again. The unit also features sparkproof connectors, short circuit and reverse polarity protection, an simple to understand charging level indicator consisting of a single LED, and practically no current draw from batteries linked to it.
