4PCS Rechargeable 18650 Battery Canserin 9800mAh TR 18650 3.7V Li-ION LED FLASHLIGHT 

I use these batteries in flashlights, work lights, and of course I have one of those strap onto your head lights for waking around at night. It’s nice to make sure all the flashlights use the same batteries. It seems no matter which flashlight you choose, they are pretty much the same except for a few features. Let’s face it, if they use the same battery and light bulb, what could be the difference? Little things like a belt clip, magnetic strength on work lights, and how the switch operates. Some have an on off switch. Simple and easy to use. But try and find a simple on-off flashlight these days. They like to put in switches with 3-5 positions. For what? Mostly advertising. Better lights will have switches with chips that allow you to us the on-off feature, and the 3 other positions when or if you ever need them. Cheaper lights will require you to press the button 3 times to turn it off.

Now onto these specific batteries. They took only took a few days to arrive. Shipping was quick. They claim to be 9800mAh which means they should last 2-3 times longer than the other, lower rated batteries I have. I have not noticed a difference. The work lights I use with a long string of LED lights last about 3-4 hours no matter what size battery I put in. Which makes me think these batteries are more like 4000-5000mAh. They work fine, but do not last as long as I expected. For the price, they are good batteries. This may be the lowest priced Rechargeable 18650 Battery on the market. I’ve used and recharged these Rechargeable 18650 Batteries a number of times with no issues for the past few months. At this point the extra 4 Rechargeable 18650 Batteries are enough for me to have a few spares when I need them.
