Parallel Battery Charger Circuits Explained

Last Updated on May 17, 2026 by Swagatam 19 Comments

In this post I have explained two methods of connecting batteries in parallel. The first one below deals with changeover circuit using SPDT switches to charge multiple batteries individually or collectively. These may be connected in parallel using a single battery charger and through a manual SPDT changeover switch bank. The seconds design talks about […]

Simple Ni-Cd Battery Charger Circuits Explored

Last Updated on May 17, 2026 by Swagatam 116 Comments

Nicd Charger circuit

In this post I have explained many simple NiCd charger circuits with an automatic overcharge protection and a constant current charging. When it comes to correctly charging a Nickel-Cadmium cell, it is strictly recommended that the charging process is halted or cut off as soon as it reaches the full charge level. Not following this […]
