- TI-89 Titanium battery drainage after water damage
- 15 Apr 2021 04:20:12 pm
2 weeks or so ago my cat knocked a cup full of water over onto my calculator. I stupidly didn't take out the batteries and just let it air dry for a day and it seemed fine for a week, until the low battery icon popped up. This was weird because I had just replaced the batteries last month, but I figured they got water damaged so I replaced them with new ones from the store. Another week later the battery icon popped up again...so I took the calculator apart and saw that the coils had some rust as well as some of the parts on the circuit board above and to the left of where the batteries go. I cleaned everything with alcohol and put it back together, as well as switched to yet another set of new batteries and it worked fine...for a day. Today, the battery icon popped up again! Is this something that can be fixed or am I going to need to get a new calculator?
