26650 Rechargeable Battery 8800mAh 3.7Volt Lithium Battery Flat Top 4 Pack 26650 Batteries for Headlamp Flashlight

Buenisimo

No sir. 3 out of 4 batteries failed within about a week. The remaining working one was manufactured incorrectly, leaving the terminal contacts way off center.When they did work, they did not hold a charge for very long. And they're expensive. Just so disappointing. Why is it impossible to get a good rechargeable lithium ion battery?

Ive charged them up but dont have an fancy means of measuring their true capacity....As a rule of thumb,if you see Very high advertised numbers that seem too good to be true, they probably Arent..these batteries claim 8800mah and theres No way these are performing at that rating...as another reviewer on here Did have the means to test them, he found them at around 2500mah... Now that seems more in line with the amount of runtime im seeing from these....I have a very powerful led flashlight that I can run 18650 Or 26650 batteries... these here Do last longer than an 18650 but do not measure up to a true rated 26650 cell...In short ,these work but dont expect the stellar run time from them that the sellers rated capacity would have you believe.

Don't hold a charge as long as they should

DO NOT BUY!This review is for the DQGG brand 26650 “8800 mAh” batteries (4 pack).The pictures speak for themselves. The actual capacity of the four batteries I received as measured by my OPUS BT-C3400 is 2648, 2424, 2390, and 2589 mAh. That is an average capacity of 2513 mAh or 28.6% of advertised capacity. That’s my worst battery test result ever!As a comparison, I recently purchased four KeepPower brand 26650 cells. They are rated for 5500 mAh. The average measured capacity of those cells, using the same tester, was 5487 mAh or 99.8% of the claimed capacity.
