OLIGHT5000mAH Customized Rechargeable Battery (217C50) Seeker 2/3/4 Pro, Warrior X Pro, Freyr, Prowess, and Odin Flashlights, with Battery Organizer

While I agree with EVERYONE that OLight should use STANDARD sized batteries, if you need to run your battery for extended periods and/or keep multiple batteries in reserve fully charged for prepping. This is a good battery at a fair price.I had to resist deducting a star to express my dissatisfaction of the battery size to Olight, that would however be a disservice for those looking for a fair review on the battery alone.*For all those out there who've heard the horror stories of "A guy died from an OLight" (search and learn it was his negligence that caused it) And for those who tell you they're not built to take the recoil of real firearms. As an instructor for the two largest national training organizations, I have run OLights on MANY calibers and had no issue with failure from recoil.

In my opinion, it's important to have Authentic Olight Batteries on hand. It's a specialized battery engineered to be charged inside the torch with its USB charger. Don't risk a fire and damaging your Olight. Only use Authentic Olight batteries.

A couple of weeks late in delivery. Product arrived as described.

I had problems with my olight, battery wouldn't charge. Olight replaced the battery, but it was the flashlight that was the problem. Resolved that and the new battery fully charges and last for several days of heavy use between charges. Will buy again.

This battery is an exact OEM replacement (back-up) for my Olight Odin flashlight.

This battery has a plastic ring around the positive post that will keep it from making contact in some flashlights. I probably did something stupid and cut it off and found out that the top plate of the battery is negative. My knife was making sparks as I trimmed it so now I don't really trust it not to short out and maybe cause a fire or ruin a flashlight. Will keep it in a case and use only if I have to. It will be a good battery if used in the flashlight it's made for

Thanks for the dead battery. I'm sure your business model will provide years of a satisfied customer base to support a growing brand

The flash light thats paired up with this little gem is phenomenally bright and well worth the price. It doesn't take just any light, so it lasts for years compared to Rabbit and Robot batteries.
