Here's an idea for making those God-forsaken triple-'A' batteries last longer than a week in your calc: build a solar-powered charging system. You could get one of those small- or mid-sized solar panels and wire it up to your batteries while they're in the calc, and when you're not using the calculator, it can be charing the batteries when you leave it out in the light...

A somewhat better idea than with I did with my other calculator: I took it apart and screwed it up so the back would not go back on. So I had to make a back and a cover for it out of a shoebox and some masking tape, and put the huge-@$$ double-'A' battery pack on the back. Now it has been dubbed "The GTI-83+ (Ghetto TI)", and is being used as a "backup server," and I hot-taped up a nice little close-and-"locking" door for the front.

Only a week? I've had the same Duracell batteries for 6+ months with almost daily use... and they're still going :lol:

Triple-'A's
Duracell: Two weeks
Energizer: Never tried.
Rayovac: One week.

Double A's: Have all lasted longer than three weeks, even with extensive usage (and even after that time I accidentally left an ASM programming running all night).

I have gotten Energizer e^2 Lithium batteries to last 3+ months when I was doing greyscale work (4 level) which DRAINS batteries

Hmm... that sounds good. I'll try those (even though I know they're probably expensive as hell - batteries getting up in the 1-dollar range here now...)

I just use ravoc 15 min rechargeables...

seems like pyro_xp2k is one of those ppl who code at least 5 hours per day for calcs (my duracell batteries never lasted more than 3 weeks for me) O_O

My batteries (some cheapo generic ones) have lasted me all through summer vacation and another 4 months of school before that with heavy usage and programming

I guess I should use emulation more often 'cause mine is blowing though 4 packs of batteries a month. I got a drarwer with at least 32 old triple-'A's in it from the calc. They're not dead yet so they just get "recycled" in other electronics til they die.

Damn, my baterries last about 6 months! hmmm,cool idea though! How long do the charged batteries last?

kalan_vod · « **Reply #11 on:** July 19, 2006, 11:39:00 am »

Well, something similar was made into the lesser calcs. The solar panel was as a back up, but also would be powered by it.

DJ Omnimaga · « **Reply #12 on:** July 19, 2006, 11:56:00 am »

i remember back when we had solar calc with no battery

...And then someone turns the lights off and everyone's answers are gone...
