Very good battery. I use them with the Olight Baton 3 Pro and the spare batteries work great in my equipment. In my opinion, they provide long flashlight operation, even with intensive use. The price is attractive, and the set includes a case for two batteries, which is very convenient for me. I definitely recommend it!

Highly recommended. I bought this as an additional accessory for the Sekret 4 Pro. Unfortunately, if you want this flashlight to continue fulfilling its search and tactical purposes, this purchase is essential.

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.
