Description: This NiCAD battery charger circuit charges the battery at 75 mA until it is fully charged, after which it reduces the current to a trickle rate. It can completely recharge a dead or unpowered battery in 4 hours, and the battery can remain in the charger indefinitely. To set the shut-off point, a 270-ohm, 2-watt resistor should be connected across the charge terminals, and the potentiometer should be adjusted for 15.5 V across the resistor.

The schematic diagram of the NiCAD battery charger circuit features current and voltage limiting to preserve battery life. The lamp L1 will illuminate brightly, and the LED will be off when the battery is low and charging is in progress. However, the LED will be very bright when the battery is fully charged.
The following diagram represents a lead-acid battery charger circuit, which provides an initial voltage of 2.5 V per cell at 25 °C to facilitate rapid charging. The charging current decreases as the battery charges, and when it drops to 180 mA, the charging circuit reduces the output voltage. This regulated and adjustable battery charger circuit is capable of charging most NiCAD batteries. It is suitable for single cells or multiple battery cells connected in series or parallel, with a maximum voltage of 18 V. Power transistors Q1 and Q2 are configured as series regulators.
Additionally, a simple circuit diagram for a 12V car battery charger is available. This circuit is designed to prevent battery overcharging, which can lead to electrolyte loss due to evaporation. It monitors the battery's charge condition through a retroactive control circuit that applies a high charge when necessary. Furthermore, this battery charger circuit is intended for rechargeable lithium batteries, utilizing a constant current of 60 mA for AA cells, with a cutoff voltage of 2.4 V per cell, at which point charging must be terminated. The system is designed for multi-cell battery packs consisting of 2 to 6 series-connected cells. Lastly, a schematic diagram for a solar-powered mobile phone battery charger is provided. This circuit is engineered to charge the battery from a source with a lower voltage and should not be used to charge a battery with the same or lower voltage than that generated by the solar panel to ensure proper operation.This NiCAD battery charger circuit charges the battery at 75 mA until the battery is charged, then it reduces the current to a trickle rate.
