The battery pack of my Roomba is made of 12 sub-C NiMH 1.2v cells; two of them are down to around 0.5v, and the Roomba won't work.
Can I replace just these two cells with brand-new ones? Will this be safe (as in "not exploding or causing a fire") if I use the same tech and voltage (and perhaps a greater or equal capacity)?
Found this question which leads me to think it should be OK, although my question is slightly different. Many other questions have safety concerns, but they're usually about mixing different kinds of batteries, or mixing voltages, etc.
I don't know what I don't know, so I thought I'd better ask!
