Canon NB-5L Battery Status

One of the junker NB-5L eBay batteries for my Canon SX-230HS pocket camera gave up, but the other two have some usable capacity left. The OEM Canon battery seems to be doing fine, perhaps because it sees a relatively low duty cycle:

Canon NB-5L - 2013-11
Canon NB-5L – 2013-11

Compare those curves with the previous tests:

Canon NB-5L - 2011-08-26
Canon NB-5L – 2011-08-26

I harvested the weakest of the four junkers to make that dummy battery.

It’s about time to pick up a few more junkers: alas, I can find no bare cells in a size to fit that case.
