Works great and no issues with charging
Bought a 14500 replacement battery for my Oral-B toothbrush and it's as if the toothbrush was new. Charging works as expected too. Delivered in a package that was hilariously big for one small battery though.

Ordered April 28, arrived about 9 days later. As always, Tenergy batteries have excellent construction and are durable. These replaced batteries in Ring Pathlights and work as well as the Ring batteries. There are many alternatives but I've found Tenergy to be reliable, well made, and they provide good product support. They have retained their charge over 3 weeks in use and hold up better compared to the Ring batteries.

Ok. Consider adults not too conversant w technology
Your recent discount helped make great batteries affordable. The handling of the package by FedX economy or whatever was very rough. The package arrived smeared all over in black grease on the outside, but at least you had wrapped in strong paper. The handling was so rough that all but a couple AAA batteries were still in their box of 24. Perhaps putting an inch of scotch tape on the top and bottom box flaps might help keep the box ends from opening and having the batteries floating around and banging together inside the bag. They looked ok to me, but what should somebody look for in terms of the batteries in a situation unexpected like that?
Very helpful and knowledgeable customer service. Website is very well designed and easy to use.
I always expect a 3 day delivery for just regular delivery. Every time, I get it the next day. Thank you so much for such prompt service.
Company was very easy to deal with to set up an account for my purchase. And very helpful when I needed something changed
I did not like it took 2 days for my order to ship

As always you have what I need at a good price. Thanks
You had the time in stock and responded quickly. Thank you.
Good batteries, nice price, quick delivery
I have received the product. Used to replace batteries in chirping smoke/Co alarms. Some it helped, one it did not. Could be improper placement of battery. They don't make these to be easy. Not the fault of the battery as far as I know.
