Apple's battery charger - hold off for now

We tried NiMH chargers a few years ago, but we gave up because of high battery defect rates and short battery lifespans.

Apple claimed to address the latter, and I was willing to try them out on the former.

Unfortunately the first two batteries we charged were defective:

The first two batteries I charged generated a blinking yellow signal. Either the batteries or the charger are defective; I suspect it's the batteries.

It could be just bad luck, but I suggest waiting a while before ordering a charger.

I'd hold off on this device for a while. Wait until there are at least forty Amazon reviews so we find out how common this problem is.
