# R2 will have to be adjusted to set the proper finish charge voltage. Flooded and gel batteries are generally charged to 13.8V. If you are cycling the battery (AGM or gel) then 14.5V to 14.9V is generally recommended by battery manufacturers. To set up the charger, set the pot to midway, turn on the charger and then connect a battery to it’s output. Monitor the charge with a voltmeter until the battery reaches the proper end voltage and then adjust the pot until the LED glows steadily. The charger has now been set. To charge multiple battery types you can mount the pot on the front of the case and have each position marked for the appropriate voltage. [...]

Automatic Battery Charger 6V-12V with Relay cut off by LM324

Automatic Battery Charger 6V-12V with Relay cut off by LM324

This be battery charger the automatic circuit again interesting circuit. Because of use IC LM324 then make economize. And can charger get both of battery 12V sizes and 6V with the filtration that at S1. Certainly circuit this still base property be when battery have voltage full already, circuit as a result order give Relay RY1 cut the system departs battery immediately. For R1 and R7 use for fine decorate the rapidity of the circuit. The test is as a result easy. Lead the battery that have Full voltage wasp with the circuit fines to decorate R1 and R7 give RY1 work. detail other part see in circuit picture sir.
