My dataline DSP battery has been acting up . Can it be rebuilt

Why not replace it?

They quoted me a price of $1200. each
I know they can be rebuilt for a lot cheaper,I just don't know how .

Expected life of a rebuilt battery vs a replacement battery?

On a different site one person said he could rebuild them for about $12.00 . He has long gone with the information .
$1200. for a new one verses $12. for a rebuilt it doesn't matter if I get a few months .
I have at least 12 old ones here to rebuild , they only seem to last us about a year .

If the cost is so low as $12.00 or even $50 vs $1,200 then go ahead.

Just as soon as I find out how to do it .

Measure the voltage and the hole size capacity. Some heat shrink and radio shack or that's what one of our CSI's looks like. Solder the wires on and whola!
