2PCS 18650 Rechargeable Battery 3.7 Volt Lithium 9900mAh Large Capacity Flat Top for Flashlights Headlamps

My hope was to replace a bad battery in a Dewalt battery pack. But when I opened it up, I discovered battery was welded in place, and would have to break plastic housing. The batteries supplied by the vendor came almost next day in a very secure package, and were completely charged, and ready to go.

This works so much better than what came in my flashlight. Will definitely be purchasing again if the need arises.

Why did you pick this product vs others?:I thought it was a good product when I read about it. I used it in my flashlight for five minutes and charged it back and a couple days later the flashlight had no power in the battery had drained so I threw it out and stuck the second one in there and it’s been good. So I basically got half of what I paid for.

They're doing the job at a much better price. The charge isn't holding as long as the more expensive batteries, but I can live with that.

Excellent product. still using them today

Same number as the batter in my product but found out the battery in my product is proprietary.

Good product

The media could not be loaded. These things definitely aren't 9900 mah... NOT EVEN CLOSE!! I Bought 2 of these to replace the the ones I have that are 2600 mah..... I knew before I even charged them that they weren't 9900 mah because they're as light as paper. The 2600 mah ones I have weigh a ton compared to these things. Fully charged they both only lasted 2 and a half hours,the 2600mah ones I have last 4 hours.... I'm not mathematician but something doesn't add up.
