    I cant and am not wanting to rate battery because haven't used it.

  • Great experience

    I love dealing with this company. They always have great communication and fast shipping.

  • I got 2 batteries. All were defective!!!

    Posted by Jason Hutcherson on Feb 17th 2026

    Horrible quality I got my batteries tested everytime. All were defective. You need to send all of your current stock of these back. Or have someone TEST ALL of them send back defective ones.

  • Great...

    Great battery came in a cook box I kept. Useful to store the old ones anyway. Battery is hog discharge and can keep going all day like that in heat or cold. It’s one you forget which is a good thing, it just works great and you don’t have to charge it every hour like my last one that was ~3 years old.

  • This is better than the energize a battery. lol !!

    They have great services and fast delivery

  • Is this really a samsung battery ?

    Posted by Ben Pupeza on Feb 17th 2022

    It came in a plain box with no markings. The battery doesn’t have factory samsung markings on it. It has a paper sticker on with nothing identifying it as a samsung 30t. It’s a battery, it works, and the price is better than a generic battery at the local vape shop. I just have no way of confirming that it is genuine samsung.

  • Great Batteries and super long lasting

    Posted by Vivian on Nov 12th 2021

    Great product, these batteries last much longer than my 18650 battery. Very happy with these

  • Tried to return, ordered wrong batteries

    Posted by Unknown on Sep 5th 2021

    I tried to contact a few times after I received the batteries and no one responded. It's past the time I can return them now, so I guess I'm out with the cost. I usually order exactly what I need and have no problems. Order wrong item once and not a word back. Thanks
