    KeepPower is my mindlessly go-to brand for rechargeables. Carried by trusted retailers such as Big Tex, high-end light makers like Malkoff Devices, and long favored by the Candlepower Forums community, I know that as long as I get these batteries from someone I trust (like Ike and his crew!), I can be certain that my flashlight won’t blow up in my pocket or catch fire to my range bag.

    With our expensive firearms and the demanding ways in which we train and use them for protection and duty, having the best – highest performing and most durable – lights on our guns becomes a necessity. The battery is an integral part of that equation, and KeepPower’s products have earned the trust of even the enthusiast base. Even comparing prices, it’s easy to see that these KeepPowers – at Big Tex’s prices – are very, very competitive, ESPECIALLY as it comes from a trusted source.

    Don’t skimp on batteries, and don’t chase a dollar or two by going with an unknown vendor or someone who may be hiding behind the veil of an online marketplace. Get good batteries directly from a vendor that you know and trust. KeepPowers from Ike is a sure thing!

    This is my first time using these types of rechargeable batteries. I like that they were included with the Modlite that I ordered. Out the box, both batteries had one bar. It took roughly 7hrs to get both charged up to 100%. Will definitely order more in the future.
