Just wondering b/c I keep thinking they'll eventually be battery leakage. I don't want my MPC being tarnished becasue of that. Well? Did anyone take the batteries out of their MPC/20TH OP?
I beg to differ. The two LR-44 button cells in my G2 Prime's voice box caused severe corrosion inside. Since then, I remove batteries from my TFs when they go in storage for extended periods of time.
I think if you have them out on display or on regular shelves at room temp etc.. I think your fine, but I would defiantly consider following Hook’s advice if you plan on storing them away somewhere, especially if its long term.
The sound box isn't in the figure, it's a separate block, so no. The button cells in my G2 Road Rocket leaked pretty badly too, but it wasn't so bad, since the wire had since been severed, anyways...
I agree, my energon ultra magnus batteries blew, corroding the electrical contacts and this killing the electronic gimmick.
Always remove batteries if you are putting your toys into storage or on display and not likely to use their electronic gimmick again. It is also worth removing them after a year or two after you get the toy, and just put them back in later when you want to use them again. This includes the button cells - they are less likely to leak, and have less corrosive material in them, but there is still a chance they will leak and damage the electronics in the toy (see below). If you want to go through your collection to remove all batteries that you no longer use, or are getting old, go to this archive of all Transformers toys that have electronics, noting which ones are sold with batteries - but don't open sealed toys just to remove batteries, as their value is in staying sealed, and people who buy them are usually not intending to open it anyway to care if the electronics still work or are corroded. Some of the worst ones I've removed (plus a couple battery tags, which were still in some toys that still leaked). Powerlinx (redeco) Jetfire weapon with button cells that leaked (this was one I never removed the tag from, and it was more corroded than the Jetfire weapon I did use).
Better safe than sorry. I use one of those medication boxes that elderly folks use to keep their pills assigned for each day of the week. Each compartment is labeled with the name of the Transformer the batteries belong to. The extra effort is a good investment vs. the threat of damage to the toy.
