So we disassembled pack B and deployed a volt meter to verify there is one cell that could only deliver around 0.1V. The rest all self-discharged to a level ranging from 0.9V to flat zero after a few days.
Out of 12 cells, only 1 held itself at ~1.3V after a week. The latter shows signs of having one completely dead cell. They’re certainly in far better shape than XV-21 battery pack. Judging on voltage level alone, pack A is in better shape than pack B. Pack B: 6.59V self discharged to 5.98V after a few days. Pack A: 7.93V self discharged to 7.64V after a few days. Fortunately, the self-discharge profile looked promising. What are the chances we have sufficient good-enough NiMH cells in this pile for one set of healthy batteries? It costs nothing but a bit of time, well within the spirit of the kind of projects we tackle at SGVHAK meetups, and so it’s worth a shot.įirst, the XV-12 battery packs were trickle charged overnight to get a sense of their capabilities, just like I did for XV-21 batteries earlier. This makes a total of four identical 6-cell NiMH battery packs. I rejected that option because new cells actually would have cost more than pre-built replacement packs.īut since then Emily found a second thrift store Neato, a XV-12 with its own failing battery pack. When I evaluated my battery replacement options earlier, one was to buy new cells and rebuild the pair of packs myself.
When I picked up my XV-21 from a local thrift store it did not power up, a fault which I’ve isolated to its failed battery packs which I’ve since replaced to get the whole system back up and running with help of ’s loan of Neato charging dock.

A Neato robot vacuum in their initial XV series product line is powered by a pair of identical 6-cell NiMH battery packs.
