The project described here protects and monitors a Lead-Acid battery against too-low battery voltage and over-current conditions. The circuit consists of MAX4373 current-sense amplifier with internal dual comparators and P-channel MOSFET in series with the battery and its load. It...

This dual-level float charger was designed for a 6V (three 2V cells) 2.5Ah battery. D2 LED was added for visual indication of charge completion, D3 indicates power, D4 LED presents overcharge condition, etc. 6V lead-acid battery charger is built using the UC3906 chip. UC3906 contains...

This SLA Battery charger project is the right choice if you want to obtain maximum battery service life and capacity, along with acceptable recharge time and economy, constant current, constant voltage, and even charge a deeply discharged battery. The project contains all the...

This project helps to optimize the 12V lead-acid (SLA) battery life as it prevents the battery from going into deep discharge. It is very important to disconnect the load before the battery enters into deep discharge as this may destroy or damage the battery cells.  The circuit shown...

Monitoring the voltage level of a 12V Lead Acid Battery (SLA) is easy and simple with this project. The board is made using an ATMEGA328 micro-controller and 12 x 5mm LEDs. The ATMEGA328 microcontroller senses the analog voltage on A3 Analog pin and drives 12 LEDs connected to digital...
