Klarus 21GT-50 21700 Battery

5000mAh | 15A Discharge | Button Top

Klarus comes out with some of the most power-packed cells on the market, and their first-ever 21700-sized cell is no exception. The Klarus 21GT-50 is only larger than an 18650 but boasts nearly double the power at most with an impressive 5000mAh capacity. The 15A drain will take care of most high-drain devices and can charge back up to 100% over 500 times within 2 hours. The built-in PTC keeps you and your devices safe against over-charge, over-discharge, over-current, and short-circuit accidents. Klarus recommends this 21700 battery for compatible flashlights, powerbanks & battery packs.

  • Notable Features
  • » Fully metal case is resistant to pressure and shock for improved durability over time
  • » Battery recharges in just 2 hours with a 5000mA charging current
  • » 15A continuous discharge supports high-drain devices with ease
  • » Multi-layer protection, including PTC overcurrent protection, microporous insulation protection, pressure relief valve protection, and a high-performance IC protective plate for peak safety and improved performance overall
Note: New battery labeling regulations require listing minimum capacity on labels. Values may differ slightly from published or displayed specs, but performance has not changed.

21700 Klarus high capacity battery

"Bought an extra 21700 for my Klarus A3. No issues. A lot of capacity!"

— John R. (5/5)

Lasted less than a year

— Mark (1/5)

Perfect

"High quality battery for my flashlight. Fits perfect."

— Scott R. (5/5)

Spare battery

"Expect this spare should last as long as the original."

— Chachee (5/5)

Not as good as past

"I have ordered this battery several times from this website and never had a n issue this is the first time that the battery performance is not good at all in the past the battery lasted 3 days with this one I am lucky to get a day and a half. And charging time has doubled. I am disappointed but I am going to try to order another one and see if I have the same issues maybe it was just one bad battery."

— Terry (1/5)

good

"bat works good"

— Don (5/5)

Klarus 21GT-50

"Works great in my light. Yes its a little long, but matched with proper charger its a high output powerhouse."

— Spiller (5/5)

Great for Flashlights

"I run these batteries in my Jetbeam lights. They seem to shine brighter and longer than the original 5000mAh batteries."

— Cody (5/5)

Excellent runtime, quality battery

"I have used the Klarus G15 flashlight over a year now and carry it almost every early morning prior to daylight. Even on the coldest mornings the performance is excellent. If I don’t use it on the brightest setting, I only have to charge it once every 2 weeks. Great battery, long run time."

— Curt (5/5)

Q&A

WHAT CHARGER WILL I NEED FOR 2 BATTERIES?
We would recommend one of the chargers in the link shown below. We have had the most luck with charging the larger 21700 batteries in these chargers. https://www.batteryjunction.com/catalogsearch/result/?q=nitecore+um
