These batteries *will* kill your slab. Even if you don't replace it, desolder it or snip it out ASAP. It looks like ArcadeShopper carries replacement batteries.

There's a bit more heat load on those pads than the usual trace, so I use my 80-watt desoldering gun for these. Excessive heat does pose a threat to the batteries as well, but unless you're using a way-too-hot iron, or heating the joint for many many seconds, that shouldn't cause any damage. I figure I may as well take this opportunity to let people know that I do provide M100 repair services -- though I'm a bit behind in completing them recently (apologies to those of you who know who you are). Also, in order to prevent these systems from needless battery damage, I've decided to drop my "standalone" battery replacement charge from $25 to $20 in order to encourage people to get them replaced. This price includes the battery and labor - return postage is extra. I'm also reducing my "with other work" charge from $15 to $12, just to be fair(er). I'll honor this to anyone I've quoted work for recently. PLEASE PLEASE get those memory batteries out! And, while you're at it, remove the primary (AA) batteries from machines you aren't using as well -- those kill too! -Josh
