6PCS 18650 3.7V 9900mAh Battery Rechargeable Li-ion Batteries with Battery Charger

PLEASE, Don’t waste your money! Buy the Panasonic brand. I bought these number one, because they were cheap and number two, because they were 9900mAh!!! I think they misplaced a decimal point because my Panasonic 3800mAh batteries last two to three days of work and these last me two to three HOURS..... I generally don’t write reviews, but I feel that it’s important enough for me to warn others.

low power batteries... most likely 900mAh not 9900... slightly longer than typical 18650 of this type by probably about a millimeter which means they have to be forced in.. I decided they weren't worth it for me after giving them a try.. I'll just shell out a few more bucks and get better batteries in the near future

batteries were advertised as 9900 mah capacity they tested at only 1000mah.

How you send dead batteries. I don’t care if they are rechargeable. New should be in working order. The battery was charged and still dead, you don’t do quantity and don’t check the quality. You don’t deserve no stars. Do not buy from them

As many others have stated, these do not even come close to the stated capacity. First off, don't even try to use the bundled charger - it is junk. I have a smart charger and after fully charging and then immediately running a 1-amp discharge cycle, some of them are around 1,100mAh and some are as low as 400! As I have read the technology involved is maxed out around 3500mAh for an 18650 so if it says otherwise it is probably too good to be true.

Not sure about these. The charger and battery melted and the battery started to expand and swell I would stay away

this batteries are only like 900 mah not 9900 as you say, bad buy for me and disrespectful

Battery charger broke before I even pegged it in. Batteries are good charger is garbage.
