Tenergy Power Bewertungen 

I have purchased 2-12 packs within 30 days 1 thru Amazon 04/30/2026 that wouldn’t hold charge and the other direct from company 05/06/2026 doesn’t hold a charge. The batteries are outdated. Shame on you Tenergy for relabeling batteries (changed label color) that have a dead shelf life and selling them as premium rechargeable batteries to consumers.

My students love the solar car project. It is the 5th year I purchased this product for my 4th grade class. Students find it easy to build in groups. They have great fun to test in on the basketball court. I recommend it for both class and in-home project for kids.

Great product. Quick shipping.

I was sent two dead batteries. I stupidly threw away my clipper which was about 17 years old. I assumed the batteries were good, but I found out just the other day they were dead when I had them measured on a meter. The meter moved about an inch, but remained clearly in the red zone. I'm not pleased, but I'll give the company another shot.

Great product, great price, nice prompt delivery. What more could you ask for?

Easy to navigate website, quick shipping, quality products

Quality product & quick service.

My order never arrived, with failure involving both USPS AND UPS.
It took over a month for a resolution, which was only done by cancelling the order and issuing a refund.
I was then able to have my institution place a successful order for the major item requested.
To my knowledge, the underlying problem was never identified.

Great products and customer service

The TN261 charger with T35U batteries are very good,also the TN261 charger made older 18650 batteries last longer before recharging. Good job on shipping to Hawaii.

Can I get rechargeable batteries with the same voltage as non rechargeables. Big impact on some uses.

I use Tenergy batteries for virtually all of my battery powered devices from flashlights, to remote controls, and telephone backups. I have found over time that the black AA and AAA are superior to the "premium" ones.

I called customer service with a few questions. The rep was very helpful. Batteries received in a timely manner and my cameras are up and working. I will definitely order again.

Product works great. Quick ship.

I'm deeply disappointed in the performance of these new Premium Pro rechargeable batteries

I bought these batteries with the expectation that they would perform as well as or better than the batteries I bought three years ago.
The Tenergy Premium Pro rechargeable batteries I bought three years ago, AA and AAA, held a full charge for at least a month when kept in storage.
I purchased the same type of batteries two weeks ago and these new batteries fully discharge within a few days when kept in storage.
I wouldn't recommend these batteries to anyone.

Your website is easy to use and allows you to place an order online.

The Tenergy Power batteries work great in the Arlo cameras. They stay charged for a really long time and you don’t have to change them as offended as you do other brands. I would highly recommend them if you are using Arlo cameras.

Tenergy rechargeable batteries keep my security camera working longer than any other! And the charging station is quick and easy! Tenergy got these products to me quickly, and securely.
