Actually...been there, done that. Rebuilt two
MP880 batteries. One I made an adapter that uses simple AAA batteries, ends up running the 880 for about an hour and a half with wifi. I had that picture posted for a long time somewhere here.
The other I rebuilt using AAA type Ultrafire lion cells that had a 1500Ah rating when I was done, using the batteries shown below from
batteryjunction.com.
First pic is my AAA adapter, and the other shows the actual sales info. The Ultrafiers work much much better than my AAA adapter.
BTW, the 10440 describes the
battery size, 10mm in diameter and 44mm in length...the same size as a AAA battery.
