hi.

I used a few circuits to charge a 12v-4.5AH lead acid battery but when the battery voltage is 12.9v the charge is no longer.

i am using lm317t for charging for now.

i am feeding lm317 with 19v adapter.
i just bought the battery and it is charging the battery with the ready battery charger adapter
current limiting resistor 2.2R

Starting multiple threads on the same topic is more likely to get you banned than an answer.

Please do not start multiple threads on the same topic, it only causes confusion.
