3 Samsung M380 Trender went for a swim; battery still shows voltage?
My 15 year old son "found his phone in the pool" yesterday. It's a little Samsung M380 Trender in which I already replaced the LCD when it was caught in a closing car door last fall (long story).
The phone is now completely dismantled & sitting in a bag of rice until I can do a cleanup with 99% isopropyl alcohol later today.
My question is specific to the battery. It has a moisture indicator which is now bright pink. However, I'm measuring about 3.3 volts across the terminals (+ probe on the + terminal, and - on each of the other two, I get about 3.29 V and 3.32 volts, respectively). I plan to replace the battery anyway, but is there a chance I can use it to troubleshoot the rest of the phone? I hate to order in a new battery only to find out the LCD is bad... or something else is wrong.
Just wondered what experience & expertise was out there on this topic. Thanks for any advice.
Es esta una buena pregunta?

Forgot to mention, the battery is labeled to supply 3.7 volts, so it is reading below it's rated voltage. But I don't know how recently it was fully charged.

For as long as it retains a charge, and the circuit protector inside the battery lets it being charged, you should be okay with using it. Of course, since you are already planing on replacing it, all you have left to do for now is to clean it. I believe the threshold for this battery is 2.7 volt.

had a few batteries with charge after a dunk...problem is they drain fast and charge slow. They're pretty cheap anyway so I tend to replace it when I'm cleaning everything else. Good luck. Some LCD's can take days and days for moisture to come out...like a sponge!
