Bought a single battery for a lawn spotlight. It came in a reasonable amount of time and for a reasonable price. I installed the battery and it gave beautiful power right off the bat.

Have utilized these types of batteries in my flashlights for the past decade. Have no complaints at all. Would highly recommend.

Customer service/ sales team was truely amazing. Have an older product with a Tenergy product that needed to be replaced due to age. The team was not only able to find and recreate the semi-custom product,, they also did it with incredible turn around time

Sent batteries in paper flat rate envelope, make sure you use a box, a paper envelope is just asking for a fire to happen. Chris

Hello, Thank you for your feedback. We’d like to clarify that the 18650 battery you purchased includes a built-in PCB, which may slightly increase its length compared to a standard 18650 cell. However, this is still within the set tolerance of 18650 battery size with PCB. To help avoid any confusion, we’ve provided the exact measurements in the product listing for customers to review before purchase. We'd also like to inform customers the order can be returned for refund if it doesn't meet your requirements. Please reach out to our Support Team if you'd like to get started with that. Kind Regards, Tenergy Support Team

I ordered 2 batteries for my solar flag light on 9/29/24. I received the 2 batteries on 10/8/24, via USPS. It was not worth the wait, as the replacement batteries were longer than the batteries they were replacing by a millimeter or two - but that matters in fittings of this type. While struggling to make the battery fit, I touched a connecting wire and broke the connection. The battery finally fit in the case, but it is immaterial since the whole purpose is lost without the solar connection. I will not order here again.

I may be premature, but so far so good for these more expensive batteries.

Cells from Tenergy have mostly been good. A charger from them was sometimes not optimal and had to be returned.
