This simple charger circuit uses a single transistor as a constant current source. The voltage across the pair of 1N4148 diodes biases the base of the BD140 medium power transistor. The base-emitter voltage of the transistor and the forward voltage drop across the diodes are relatively stable. The charging current is approximately 15mA or 45mA with the switch closed. This suits most 1.5V and 9V rechargeable batteries.
The principle work of the charger is between one batteries with other battery dissociated by packer wall which there is in battery box, mean every space at battery doesn't correlate in consequence electrolyte fluid at every battery nor correlates (partition wall between batteries there shall no which leak).
In one batteries there is arrangement of plate that is some plates for positive pole (between plates dissociated by timber, ebonite or plastics, depends on technology applied) and some plates for negativity pole. Active agent from positive plate made from chocolate tin oxide (PbO2) while active agent from negativity plate is tin (Lead) pore (like sponge). The plates soaked by electrolyte fluid that is sulfate acid (H2SO4).
