Great substitute for single use batteries
Simple to charge. I'm not sure how long the charge lasts compared to a single use battery, but I ran a small set of LED lights pretty much all day with one of them.

Great Buy!
Great buy! We bought these for an outside dog bark deterrent. OTC batteries last about one week. At about $4 per battery... We charged these suckers up, placed in deterrent and the battery lasted about 1 month! We are super impressed. We knew we had to share!

Economical
The only issue that kept from giving 5-star review is the overall dimensions of these batteries. The width and height is approximately .6 to 1.0 mm larger than typical alkaline batteries. That's not much, I know, but on some devices (temperature gun, multimeter) the battery compartment has exact dimensions, and these batteries are a TIGHT FIT.

Charging indicator - red=charging, green=charged. Description: blinking=charging
The product description says:LED INDICATORS MANAGEMENT】When charging, the red LED will blinks and will then LED remains on once it is fully charged.However, the 9 volt batteries I received show a red LED when charging and a green LED when the charge is completed.That's a problem for me -- I have red/green color blindness and can't see the difference. I specifically ordered this product because it said it blinked during charging, and changed to a steady LED when the charge is completed.Was I sent the wrong product?

Very nice
That fact that these are rechargeable makes them great. I save so much money on not having to buy so many batteries.
