Re: TI Programmer Battery Message #2 Posted by Ron Ross on 27 Apr 2004, 11:23 a.m., in response to message #1 by john taylor
You can rebuild the pack (fastest, easiest solution), if you still have the walwart charger. If it has a 9V battery plug (some do), you can just gut the battery pack and then use a 9 V battery.
Else check with a Ti site (forget off hand, but a google search should give you one). You can buy rebuilt packs or buy a Ti-55 or compatable calculator and rob its pack for your calculator. I only give the Ti-55 as an example, its pack may not be compatable (I have a cross reference chart, but it is at home and I am at work). The Ti-55 is usually cheap and readily available, but be warned, all these calculators are 30 years old and their battery packs are also probably shot.
You could have someone rebuild you unit here as there is nothing really tough about rebuilding a battery pack and it is best done with a resistive welder vs solder (though I use solder often, since I no longer have access to a resistive welder). Actually, I try to buy battery packs of the cells I use from Radio Shack in cell packs which works best.
The best work is usually done by those who do it most often. If you value this somewhat rare Ti, and want a professional job, contact an Hp repair guru for best results. Older Ti's do not generally warrent the fees or attention of these guys, but the programmer is a more rare model than most.
