ultrafire 3.7v Customers Reviews

  • Fast shipping, value for money.

    Valued for money. Comes with Battery box to hold 4 batteries when i only purchase 2. Cheap and good. full charge at 4.2 volts and batteries run dry when its at about 3.2 volts.
    for its price this is a definitely must buy for anyone who is looking for a 18350. packaging is good and shipping is fast.
    Nice person to deal with. effortless and fuss free. Not to expect too much from the batteries but then again it is indeed value for money. Will be purchasing a few more.
  • Good charger for resonable price.

    - compatible with most of LiFe and Li-ion batteries- can be powered from 100 to 240V (US to Europe)- implemented auto-cut-off protection- buil in timer (6 hours as stated in manual)- easy to understand charging lights - green - OK, red - charging, so easy- selectable current 300 or 650mA - can be used from smallest to biggest capacities- selectable voltage for Li-Fe and Li-pol (3,7 and 3,2V)- two separate channels, can charge two diferent batteries in the same time.
    For this price it is a great cahrger, with accurate charging. 1st channel 4,15V AW17670, second 4,20V AW 18650.During charging it´s a little warm but nothing serious, still can keep in hand.Adjustable negative plate working fine, giving god contact with battery.LED is blinking every one second RED-GREEN durring charging, as I found internal chip (Samsung IC) is checking voltage.
    Ordered second one for my father as well. I´m happy so far, he will be too.
  • Good capacity

    The tital of UltraFire Protected 18650 3.7V 2400mAh Lithium Batteries looks to be a very close match.
    And they work with all my 18650 torches.
    I'm a big fan of Max mAh to size. And these are not very good. But they do come in at good value.
    Might combine the todger and vacuum soon.
    Sellecting the correct cells to go with different applications is a case of suck it and see.
    For me this cell works as a low power requirement and not too demanding on the storage size.
    Bottom not so great with the vacuum but todger is fantastic.
  • very happy

    for now every thing is perfect.got it, used it,enjoying it.
    I am not sure about the capacity, but I don't really care. the price is so good that even if it is half of 6000 I will be happy/I got it for my 13000lm flash light. Just notice that these are fatter than the 18650 ones. so my charger can charge only two at a time and not four.
    I am happy. they should be ok for about 40min on my extreme strong flashlight, so I have already ordered 12 more batteries.
