you cheap bastard....

nah.. but you could probably get a desktop charger for the battery on ebay for less than $10 (just the base without the plug to the wall) - but then you mangled your transformer..

You'd just be throwing your cash away though cos you'd get so annoyed swapping the battery in and out that you'd never use it anyway

Can't polish a turd

Time to let it die, euthanasia is the only humane way to deal with the situation.
