I have a bunch of iPowerUS which are great. They are expensive and max out at 520mAh and still going after 10 years. Good enough I use them in smoke detectors and change every 6 months.
I also have bunch of EBL, claim 600mAh, have about 450, and are starting to dwindle after 2 years.
So, I'd expect these likely might go 400mAh and die in a few months to a couple years.
They WILL cause electronic interference in sensitive devices.
Note-still better than 9v NiMh which are pathetic.
However, out of the 4 I've bought only 1 still holds a charge after 2 years.
The others ones only hold maybe a 20-30% charge.
That said, Chinese battery tech has improved significantly over these 2 years and have become more reliable so ymmv?
