Although I've never seen it happen firsthand, one thing I've heard of quite frequently over the years are TI calculators that seem to drain batteries in an excessively short period of time for no apparent reason. I guess somehow something in the calculator circuitry develops a defect that draws excessive current from the batteries in these cases.
I know DJ's 83+SE had this happen to it. :(

Good luck fb39ca4! :)
Yeah :(

Power is drainer ridiculously fast when the calc is turned OFF.

I hope the batteries didn't damage anything x.x

Btw when a battery explode literally, does it do a very loud detonation and large explosion like  fireworks or a grenade? :P

I think that if this would've happened, his calc would be dead. x.x

We never know. Maybe these things are more resistant than you think. ;D

It just went bang, sort of like a small firecracker.

Last year, I dropped my 89 from the top of my locker to a very hard concrete floor.  It hit at such an angle that the battery cover came off and all 4 batteries came out.  There was not one scratch on the calculator though! :)

Now that we are on the topic of batteries, I have always wondered this:  What is better, Energizer or Duracell?  Every time I test my batteries, the Energizers tend to have a higher charge.  But their pink bunny makes me suspicious.  You just can't trust a pink rabbit.

I personally prefer Duracell, they seem to last longer for me, and they're not as flashy.  :P

Yeah, I was pretty freaked out ... like most people, I take it for granted my batteries won't explode in my calc.

Ah, irony...

And seeing as this isn't in Randomness, that's a bit disturbing. What brand of batteries?

I prefer Duracells as they seem to last longer but at like $8 per battery set (4 AAA's) I prefer the $1.49 sets of 12 batteries at the dollar store. I didn't have problems with them yet and in the end I end up saving money despite the fact they last like 4 times shorter.

Having that happen to me would definitely startle the heck out of me. It could be a close call for sure—I once (around 10–12 years ago) saw a story on the news about a children's toy with a battery compartment where the springs were somehow damaging the battery's insulation and causing it to get shorted out. The guy who had taken them out said that the moltern battery guts got squirted right in his face or eyes.

Ouch, seems expensive over there. Where I live (though I don't know what the difference between U.S. and Canadian dollars is right now), a few bucks more than $8 will get you a pack of 4 AA or AAA NiMH rechargeables. That's what I've been using for years now for almost everything, because I go through batteries quickly and this way I only have to buy new ones every few years instead of every few days or weeks. In some devices like TI calcs, though, it's tricky because the battery low warning doesn't take NiCd/NiMH characteristics into account, and the calc can end up dying without warning when they run down, in some cases causing a RAM clear. To avoid this, I just get in the habit of swapping them out for recharging every so often before they have a chance to get low.

Wow, I just got 4 new rechargeable batteries (AAA) for $6 ... and they're 1000 mAh, unlike the $12 850 mAh ones I had...

Well, $12 for 850 mAh was Energizer (talk about brand pricing :P), and the $6 one for 1000 mAh was from Polaroid.

EDIT: Just realized, they're actually 850 and 1000, respectively.
