High Power 3.7V Batteries 18650 and UK Charger Kit, Powerful Batteries for LED Head Torches/Headlamps/Flashlights/Video Doorbells, Not for E-cigs

Excellent product, the only reason I gave it 4 stars is the confusion over the charging LED's, (green-charged, red-needs charging).I put in two totally flat batteries exactly the same as the ones that came with the charger, and the green LED came on, so I tried them in the product again, which is a 'Motion Solar Security Light' the result was zilch, totally flat. I then put in the 2 that came with the charger and the security light works fine.I am now in the process of re-charging the above same batteries and guess what, yes the green LED came on 'help' can somebody tell me what's going on.

Title says it all. The listing states and shows the 2 batteres are flat topped - they most certainly are not as one end has a protruding terminal making them unsuitable for the appliance I needed them for.The charger itself is sturdily built with a corded UK 3 pin plug attached. Only really designed to take the larger 18650 batteries (it will take the 18650 flat topped) it is not suitable for any other sizes.Also note: returns are not free and postage will have to be paid (all or part of it may be refunded).Can't comment on speed of charge or how hot unit might gat as it never got used. Returned.

not sure what to say really, I use them in a torch and they work very well, the torch is used every night for about an hour and the battery seems to last about 4 days, I will say one battery does seemto make my torch brighter than the other but that could be an allusion.

I ordered this because l do a lot of Cross Country Running and l needed some spare rechargeable batteries for my head touch. They came really quickly and seem to be very good, the only reason I’ve given them a 4 star rather than a 5 star is because they are a bit heavy, they are quite a bit heavier than the rechargeable batteries I’ve already got in my head touch but as I only need them for a back up just in case they’re fine.

I bought these because the batteries in my video door bell don’t last long so its good to have a back up on charge..

Just bought this to enable the ringer to work, not a standard size so cant use it for anything else, very cheeky.

Very good item, it does what it says on the description, i bought it to charge the spare batteries for my Video doorbell

I’ve been using this for several weeks now and it’s all still working perfectly
