By maintaining a regular charging routine, you can avoid premature battery failure and save money in the long run by not having to replace the battery frequently. Diode D5 ensures that the IC doesn’t get damaged in case the battery accidentally gets wrongly connected with reverse polarities at the output.

A current controlled automatic 12V battery charger circuit with 4 LED indicators can be learned in the following post.

However, it is not recommended to use a fast charger on a lead-acid battery as it can shorten the lifespan of the battery. As soon as the connected battery is charged fully, the potential at the inverting input of the opamp becomes higher than the set voltage at non-inverting input of the IC.

Once you’ve started charging, let the process continue until the voltmeter on your dash reads 14 volts or higher. How could you figure the largest battery you could hook up to a battery backup and have it charge fully? If you plan to make a 12V 7Ah battery charger, make sure you have the necessary components and follow the steps mentioned above.

However, it is important to note that the actual run time of the battery may be less than this due to factors such as environmental conditions and the age of the battery. The above LM317 battery charger circuit was suitably modified using fixed resistors, by one of the dedicated members of this blog Mr. Monitor the charging process: Regularly monitor the charge controller’s indicators to ensure the battery is charging correctly and the charge controller is functioning as intended.

Recently, I had the opportunity to test the internal electronics of several popular Router UPS devices. However, they also have some disadvantages, such as requiring regular maintenance (such as adding water to their cells) and having shorter lifespans than some other types of batteries. A simple trickle charger will take much longer to charge your battery than say, a fast charger or an automotive charging system. The crude charger consists of two stages – the first is a 15V/2A SMPS, and the second is a standard recovery rectifier 1N540x, which prevents reverse current and also lowers the charging voltage a bit (1V maximum).
