Haven't used the charger yet... I might in the future. Bought these after purchasing a new head lamp at menards that uses 2 swappable 18650 button tops. I used a battery tester that fully charges the battery then discharges them at a selected rate (i used 1000mah) and then fully charges them again. I performed the test twice. The ones that came with headlamp were rated at 1200mah and tested at 1150ish each... these being rated at 3400 tested at approx 2900mah each. I wasn't surprised and am happy with it. Giving me much longer use time obviously. I like the battery holder... it's very convenient and seems solid. I can now keep my 1000lm headlamp running all work day. Hope this helps.

The charger and batteries did everything I expected them to do. The charging process went from red to green just as advertised in a reasonable amount of time. The batteries fit the flash lite just like I wanted them to. The packing and holding case were solid and very professionally done. What makes most products disappointing is the negative things, cheap and junky, this product has none of that. Although I did not verify it, I expect that the 3400mah "spec" is meet base the feel, appearance, and performance. Overall, a good solid product.

Love that the batteries come with a back up charger! Makes life so much easier! They work well for replacing the batteries in my outdoor solar camera. Nice to find batteries that are well worth the money.

Checked voltages of all batteries and they are fully charged. Great price for 4 batteries and charger.

Hopefully these 3.7v batteries will last longer than last 2 other brands/manufacturers. Will not know for a couple of months. If they do last, would rate 5

No complaints so far. Batteries work as intended. Charging takes a bit to charge fully but that's normal for bigger Batteries. Good value for the money!

Who knows if these are as-rated? The charger is kind of messed up, and the light stays red even when the batteries are charged. After being on the charger for hours one side was still red and the other was sort of green and kept going back to red, I put them on another charger and they were charged, so I know it worked, but I don't know if it had kicked off or if it would have cooked the battery if I had not removed them. The batteries did come in a nice case and seem to work well in a couple of flashlights, so I will conditionally recommend them.
