    Excellent Batteries

    Posted by David D. on May 15th 2017

    Orbtronic is the only battery that I have had any success with. Have tried many others. Orbtronics hold their charge longer than other that I have tried and produce I think pretty close to their stated ratings. Overall a satisfied customer

    Great batteries

    I bought these to add to the stable of batteries. The 3400s I have work incredibly well. I expect these will too.

    Excellent batteries

    If your looking for top of the line batterys for a super powerful flashlight, get these. I have an olight marauder x7 (9,000 lumens) other generic batteries you pick up from a store won't reach max lumens and barely half the lumens. These batteries reach max peak.

    High Quality

    Always a quality battery. I've tried others for a few dollars less but always comeback to Orbtronic for high quality and fast delivery.

    These have a smaller diameter than other brands of protected cells that will not fit into some of my flashlights. The Orbtronic cells fit into every flashlight that I own.

    Simply the best 18650 battery available!

    Posted by Tino R. on Apr 25th 2017

    OrbTronic is the best in the business when it comes to Li-ion batteries. I've tried many batteries over the years and settled quickly on OrbTronic. They have good prices, EXCELLENT performing batteries and they last a really long time. Mine are recharged almost every day as I use my flashlight daily. So far they've held up really well in over 3 years of hard use. What more could you possibly want? Bottom line: when you want reliability and peace of mind, you purchase OrbTronic, end of story!

    Posted by David F. on Apr 25th 2017

    I’ve used these batteries for several years and reorder more because they hold a long strong charge and are very durable.
