  • Excellent battery size 18,650

    posted by Faust02

    The new line of batteries from a famous Chinese brand. Quality performance at a high level, it is nice to hold. were purchased for installation in power bank, now with field trips I always have a supply of energy to charge your smartphone. Very happy with purchase, would recommend.
    It would be desirable that the goods purchased in the shop went faster, sometimes have to wait very long.
    All in all very pleased with the service in the store Deal Extreme, products are always high quality, the prices are quite nice.
  • Working well for me.

    These seem good capacity, I'm using them as a set of 4 cells in a USB power bank (sourced elsewhere) and they're capable of charging a variety of devices multiple times. 4 of these are giving me at least 2 full charges of an iPhone 5.
    I haven't measured the individual cell capacities of these cells, but I've been happy with the capacity so far.
    If you need unprotected cells, then the TrustFire brand seem well respected and have so far, served me well.
  • Excellent. Very good price. Great Seller

    Easy to recharge. Very fast delivery.The batteries are very long. The recharge time is very short. The flashlight works perfectly. I have similar and already have two years of continuous use, without symptoms of wear. They're better than AAA or AA batteries. They last much longer and the light intensity has no comparison.
    Highly recommnendable.Easy to recharge. Very fast delivery.
    I will buy another, soon
