    Lithium-ion rechargeable battery UltraFire format 18650.Lity-ion batteries (Li-ion) are used in most modern electronic devices, including LED flashlights. They have high energy density, no memory effect, virtually no discharge over time and does not require any special maintenance. Protected batteries are different from the usual ones that are embedded board protection against short circuit, overcharge and overdischarge.
    This protected batteries can be charged not only with a special charger, but also by any battery charger providing voltage 4.2V.
    If you exceed the voltage circuit will automatically shut off the charge.

    -cheap price
    -seems decent quality. the edges match up and feels smooth.
    -after reading other peoples comments i shook it to see if i could hear any loose items... and nope no sound.
    -also unlike others mine does not hum or make any noise, either when charging or when fully charged.
    -the spring is firm... but not overly so.
    maybe i got a good one, or the quality has improved. but i have no complaints and find it very good
    Very Good
  • lithium iron phosphate battery

    The capacity is 1350mAh. (it actualy is)The maximum discharge rate is good. (~5.5Ah)They are the same size as a normal 18650 battery.If you put them in a serie of 4 you get the same voltage as a car battery. (with a lot greater voltage range 8.8v-14.4v)
    i had ordered 8 and put them into SKU 103855.all seemed fine until i checked the volage of them 1 row of battery's was fine the other had a dead one. 2 battery's were on 4.8volt 1 on 0 and 1 on 3.4. so i discharged the onesat 4.8 to 3.4 and they seemed to be ok. after about 1 week i checked those battery's again and there was another one dead. however the overvolted battery seemed to be as good as the normal one.
    if you are looking for a battery to replace an 18650 battery there should be no problem with these. they have a good capacity and discharge rate.
  • Protected cells at an attractive price.

    The cells comes nicely wrapped, so they wont get damaged during shipping.- Excellent price for two batteries.- Protected cells!- Comes pre-charged (most likely charged, due to the chemical process, when they were manafactured)
    Rather see some cells with an accurate capacity label - at least DX says that its not to be trusted.
    Decent cells for the price!
