It's hard to figure out your problem. For example, I've never heard of a "sunhurn booster battery." I googled it and nothing came up. Surely you don't mean Sunhans because you spelled out "sunhurn" twice. Sunhans makes amps, not batteries. So I don't know what you're talking about. Please try to explain your problem again, be specific, and make sure you are describing your problem well, and spelling things correctly.
