Olight ORB-217C50 INR 21700 5000mAh 3.6V Protected High-Drain Lithium Ion (Li-ion) Button Top Battery

"Probably the best powerhouse battery on the market"

— JOHN S. (5/5)

Put a Baton back in service

"Purchased multiple sizes as backups as some of my lights were starting to feel a bit-tired battery wise. This measure should provide additional years of worry-free useable life."

— Jack R. (5/5)

Olight button top 21700

"It also works with the Thrunite 21700 flashlight."

— ROGER L. (5/5)

Excellent Battery

"It's a real pain that Olight utilizes proprietary batteries but I did get 4-5 years out the original one that came in the box. Towards the tail end of it's lifespan, the light could only maintain its Turbo setting for mere seconds on a full charge so I knew it was time to replace it. I'm just glad that this battery is still available!"

— Eric I. (5/5)

Olight ORB-217C50 INR 21700 5000mAh 3. 6V

"Just bought an Olight Warrior 3 directly from Olight. They were out of stock for this battery. Was great to find them here at Battery Junction. They almost always have items in stick and even sometimes at great sale prices. Quick fast shipping too."

— Charlie A. (5/5)

Glad Battery Junction is there.

"I love Olight flashlights, but am not so pleased about the custom batteries some of those lights require. Often they do not have extra batteries in stock for me to purchase as back-ups or quick replacements when needed. Enter Battery Junction. It is really nice to be able to get those batteries from a reliable source, and sometimes even at lower prices. Thank you, Battery Junction for being there for us."

Expensive but with it

"I use this in my Olight Warrior X Pro as a backup cell. The X Pro is an amazing light, but if you need extended run times in the field it’s great to be able to swap in a charged battery and not have to worry about needing to charge the only 21700 battery that fits. Expensive as batteries keep creeping higher in price, but worth it if you might need extended run times and don’t have a charger available."

— Eric (5/5)

Does its job in Olight Seeker 2 Pro

"I bought this battery so I could have a spare to my Olight Seeker 2 Pro. Like the battery that came with the light, it arrived at about 3. 58V and took over four hours to fully charge to 4. 20V. As with other Olight customized batteries, (rechargeables dedicated to a certain model flashlight) it has to be charged while in the flashlight with the magnetic charging system. It would be nice to be able to charge it outside of the flashlight in an external charger, such as the Nitecore SC4, but it can't be. It wouldn't fit anyway because of the plastic rim around the positive terminal. The battery measures 75. 5 mm long. The battery performs as expected and I am happy with the purchase."
