Review for model:

There is nothing to complain about. The battery works well, has the actual capacity and a reasonable price. It was purchased to replace the old, very weak batteries in the XRG flashlight, which were of terrible quality. Unfortunately, environmentalists do nothing about it.

It fits perfectly with the Theta Light angle flashlight from this offer. The dimensions match completely. As for durability, time will tell, but I don't anticipate any problems since I've encountered these batteries before.

Very good battery, the actual capacity matches the declared one. I use the 186500 and 21700 models from this company and have never encountered any problems. The battery is equipped with protection, which makes it 5 mm longer than typical ones, so it's worth keeping this in mind.

Review for model:

Purchased as an additional battery for the XRG Sport H20 flashlight. It has a higher capacity than the original, which makes the flashlight work longer. I am satisfied and recommend it.

Very good battery, the declared capacity is true to reality. I use the 186500 and 21700 models from this company and never had any difficulties. It has protections, so it is about 5 mm longer than standard, which is worth keeping in mind.
