Hi Kristan.
To improve your odds, you must resist the temptation to reinsert the battery to test, not until at least 24 hours later and after disassembly. If the cellphone/PDA is still wet inside -- ZAP. It can take weeks for the inside of a cellphone/PDA to fully dry if you do not disassemble. It can take less than 24 hours to dry if you dissemble first. So disassemble first(If you know well how to do it)!
Now where the battery is destroyed, you have to remove it anyway and get a new one to do any further test.
