https://www.electronics-lab.com/dual-level-float-cum-boost-charger-with-pre-charge-for-12v-3-to-6ah-sealed-lead-acid-sla-batteries/
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 necessary circuitry to optimally control the charging of valve-regulated lead-acid batteries. The […]
Lead Acid Battery Voltage Monitor using ATMEGA328
https://www.electronics-lab.com/lead-acid-battery-voltage-monitor-using-atmega328/
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 I/O pins of the chip. Input […]
