Yeah, replacement batteries are pretty cheap. In theory you could swap in a fresh one as needed. I'm wondering if there's such a thing as a phone battery charger -- the kind you insert the battery into, rather than plugging in the phone.

Yep, for many more popular phones with replaceable batteries there are, could be for yours.

It may even charge with a generic Lithium type charger if it was wired up right.

Yep, I got one with moveable pins so (in theory) you line them up and it charges any battery that the adjustable grip can hold.

I have no idea whether it works - have tried it with two batteries but in both instances I don't know whether the charger is crap, the battery buggered, or the phone fucked.
