Olight 21700 3,6V 5000mAh Battery

The 5000 mAh battery in 21700 format works excellently. It provides long flashlight operation and is very reliable. The built-in protection (PCB) is a key safety feature. I definitely recommend it.

I had the battery included with the flashlight, but it lasts very short. The price is completely disproportionate to the quality and the manufacturer's claims. I do not recommend this product.

Great battery, lasts a long time – I've been using it for over a year in an Olight headlamp and I recommend it. It would be great if external chargers were made for them.

I bought this battery as a backup for the Olight Seeker 4 Pro. Surprisingly large capacity for such a small and light cell. Perfectly made, with overcharge and over-discharge protection. Looks like a premium product. Recommend.

I use the battery in the Seeker 4 Pro flashlight – one came in the set, the other was bought separately. Despite frequent use, I still haven't been able to fully discharge them.

Very good battery. I use it in my Olight Warrior X Turbo flashlight. At maximum power, it performs flawlessly. I have four of these batteries and none have let me down.

I use it in the Olight Warrior 3 tactical flashlight. The battery holds its energy for a long time and comes packed in a practical plastic box for two cells.

I bought two batteries for the Olight Perun 2 and M2R Warrior. They function perfectly and hold a charge for a long time. I practically haven't noticed them losing charge without use. I always have the M2R Warrior with me and it works for months without needing to be charged. I use the Perun 2 on night walks with my dog and it also barely requires charging, maybe once a month.

Everything is fine, the battery is solid, heavy, compact, and has a big capacity, charges quickly and fits the flashlight. It holds energy for a long time, definitely recommended for replacement. Delivery was lightning fast.

I chose this battery as a spare, because it's not standard and hard to find in a store. Lasts a long time, I'm overall satisfied. The purchase went smoothly and very quickly.

I bought an extra cell as a backup for the Seeker 2, and I intend to use it as a replacement in the Perun 2 as well. I recommend it. As always, shipping was lightning fast.

I bought it as a backup for the Warrior X Turbo. I appreciate that militaria.pl included a plastic case – thanks to that, the battery doesn't rattle around in my backpack. Recommend. And the Warrior itself for patrol as well :D

Great battery – very large capacity means the Baton 3 Pro Max works for a really long time. It's good to have a spare, especially for longer trips out in the field. Sometimes maximum mode is needed and then the battery level drops quickly.

This is a really great battery – its large capacity means the Baton 3 Pro Max lasts for a very long time. For longer trips to the forest, it's worth having a spare. Sometimes the highest mode is needed for a prolonged period, and then the battery discharges faster.

Works perfectly as a spare battery for the Perun 2 flashlight, has large capacity.
