Hello every body, Please I need your help to solve a problem. I have an inverter which I use with my 12V battery. Recently, after I changed the acid, it started running down too quickly. I have it as the only power source. So I want to know if I can build a charger that I will use the output ac to recharge it. Please I need you to help me fast. Much information would be appreciated. my e-mail is realid2netting@yahoo.com.au
