This article looks at an effective way to charge batteries without using relays. Rather, to complete this duty, we will use a 78XX regulator IC and a Bipolar Junction Transistors […]

You can build an auto cut off battery charger circuit using a single IC 741 in a comparator configuration. Let’s learn how? Understanding the Circuit for a Single Op-Amp Charger […]

Any kind of lead acid battery may be charged at a specific rate using the most basic lead acid battery charger circuit described in this article. This article describes an […]

Although the majority of battery chargers use voltage detection to initiate automatic shut-off, current sensing is a more accurate technique. Upon the battery reaching its optimal full condition, this method […]

This article describes a clever and simple automatic battery charger circuit that only uses two transistors! This circuit automatically adjusts the charging power based on the battery’s charge level, by […]

The inexpensive battery charger circuit with only one transistor is intended to cut off the battery’s supply immediately when it reaches its maximum charge level. This article describes a very […]
