Olight 18650 3,6V 3400mAh Battery

I definitely recommend this branded 18650 battery. The actual capacity is 3400mAh, which matches the specification – the battery lasts a long time and discharges slowly. A big advantage is the built-in PCB module. The product is worth every penny spent.

High-quality battery. After long storage, it didn't lose capacity, unlike cheap replacements. Capacity matches the description, and the price is fair.

Great battery. Holds energy for a long time. As described by the manufacturer. The package was very well secured and arrived quickly.

Very good high-capacity battery. It's definitely better to buy a decent one that lasts longer than to keep replacing weak batteries of unknown origin. After more than 2 years of use, I haven't noticed any drop in capacity.

The battery is fine – but remember, it requires a separate charger, e.g. Omni Dok, because it won't charge directly in the Olight flashlight (in my case S2R Baton).

I recommend to everyone! The Olight 18650 lithium-ion battery is equipped with protection (PCB) against overcharge and short-circuit. Nominal voltage 3.6V, capacity 3400mAh.

Excellent quality battery; I chose Olight because of its solid build and good parameters. This battery works better than previous ones I have used. I highly recommend it.

Solid rechargeable batteries, as described by the manufacturer. I use them in my camping flashlight; I use them daily at work and on trips.

The battery works as expected. I use it in the Olight Baton S2 flashlight, everything is perfect. Allows you to use the strongest mode. Highly recommend.

The Olight battery is so far the only product from the store that I can't rate very positively. Before giving my opinion, I conducted a test for reliability, comparing it with a 3000mAh battery. I was surprised that, after full charging, the Olight had the same capacity (3000mAh) and not 3400mAh as declared by the manufacturer. The test involved running the flashlight on the brightest mode in a room with constant temperature. Both batteries lasted about 5 hours, so in reality the capacity of the Olight matched that of the cheaper battery. I expect to get exactly what the manufacturer states when buying Olight. On the plus side, those 3000mAh are sufficient, unlike other brands that are worse. I give it 3 stars only for acceptable capacity, but I expected more.

If you’re looking for a branded, reliable battery for your flashlight, this one met all my requirements. It’s capacious, has protection, and lasts a long time. That justifies the higher price – quality costs.

Very good battery for a reasonable price. Product matches the seller’s description. Fast shipping and excellent shipment protection against damage.

The battery is excellent – protected against overcharge and over-discharge, and the declared capacity matches reality. It’s definitely a product worth recommending. Better to pay a little more and avoid problems with cheap substitutes.

Very good battery – matches the description. Lasts a long time. The package was well secured and shipped quickly.

Olight is a brand that needs no introduction. Very high-quality batteries at an affordable price. Safety and long usage time justify the slightly higher price. I recommend it!
