Pay attention to overall length!
Michael E. Stora, Ph.D. (Maricopa, AZ) 5/13/2015 11:35 AM
A good cell at a good price but they are almost 73mm long and fit . . . almost nothing . . . I even dented the positive terminal of my intelecharger trying to fit it in. I ended up debuttoning and re-wrapping them. Check out product 9470 which is about 2.5mm shorter and an even better price per AHr.
Great Potential

Everything I've ordered from batteryspace has been great. I didn't measure the holders I have first (listed in related items), so charging is a bit tricky. With the capacity these have, I look forward to finding a new use for these cells someday when I find a suitable holder. Having the PCB built in is a plus.
Great shopping experience
