Abstract
A battery charging device uses a primary battery source which is preferably a rechargeable lead acid battery, connected to a secondary battery source, which is preferably a pair of parallel battery circuits each using series-connected non-rechargeable batteries in series with a diode, the primary and secondary battery sources providing a charging voltage output. A switch has a first position in which the charging voltage output can be supplied to an external battery which is to be charged and a second position in which a recharging voltage can be supplied from an external source to recharge the primary battery source, and a third, or off, position in which charging and recharging operations cannot occur.
Claims13
A battery charging device comprising
- a first low-amperage rechargeable battery source providing a first voltage output;
- a second low-amperage non-rechargeable battery source circuit removably connected in series with said first battery source and providing a second voltage output, said first and second voltage outputs providing a charging voltage output;
- switching means connected to said charging voltage output, said switching means having a first position for supplying said charging voltage output to an external battery which is to be charged, and a second position for supplying a recharging voltage from an external source to said device for recharging said first battery source.
