Don’t buy them - capacity max 1500 mA !

    I’m really anger! Those batteries from circle to circle has less capacity than advertised. In details:

    Charging Charger (sku.6105) charges up to 4.22 – 4.23 V. Exactly as it should. Charging time from 4h 05min till 4h 15min.

    Discharging Flash light which drains 700 mA in average. I don’t want to let it warm too much so: 30 minutes flash light ON, 20 – 30 minutes OFF till flashlight goes completely cold. After that once again 30 min ON and so on until battery protection circuit cuts off the power.

    Results Total flash light run time:
    150min (first discharge),
    135min (second discharge),
    finally just finished third time – 125min.

    Calculations
    700mA * 2:30h = 1750 mA
    700mA * 2:15h = 1575 mA
    700mA * 2:05h = 1458 mA

    Advertised capacity: 2400 mA

    Additionally I ensured that not only one battery discharged but all 3 of them. My flash light uses 3 batteries. After it switched off I removed all batteries, placed two additional fresh charged and the third one which was in flash light. After that flash light works less than 1 minute until this third battery protection circuit switches on. The same results I got with other two discharged batteries. It means that all three batteries are completely discharged on average 700 mA load after a little more than 2 hours.

    Reason??? I just guess, but it looks like these cells are old. Li-ion battery capacity goes down very significant after 2 years even if this battery placed in warehouse. I read from comments that were significant drop in price for this SKU. Maybe it’s because vendor wants to sell old stock?


    I’ll going to request for replacement to another brand or something. Actually I don’t know what to do… I need good batteries for my flash light – not 50-70% from advertised.

    several times ive heard that the maH is determined by a 20mA drain.

    the number goes down the higher the drain.

    Capacity with drain 0.5A is 2050-2100mAh.
