I have a portable rechargeable amplifier that was custom built for me when I was in Peru, it no longer makes sounds when unplugged, although an LED lights up. When plugged in to the wall, it emits sounds.

I opened it up today and noticed the 12v 4.5ah battery was bulging, and I am pretty certain that is the culprit.
But, I suppose further details could help clarify the problem. I let a friend borrow it, and when it came back it would no longer hold a charge. Seeing as Peru uses 220v, I have a step up/step down convertor to allow me to use it in the states [I suppose here, I need to step-up the power].
Anyway, I've noticed that now the amp works when plugged directly into the wall without any transformer, that's probably not a good thing, but it can do it anyway.
I looked inside the amp and no capacitors look blown and the wiring looks fine, I think it's the battery, but maybe there could be another issue. And why would the LED still light up if the battery is bulging? Does it still hold a minute charge?
