18650 battery 3.7v trustfire Customers Reviews

  • Nice batteries, but not for laptop

    posted by RomByDan

    Nice quality so far - I see no degradation after 3 months of heavy use.
    With these spacers on + terminal I don't need soldering - they fit tightly inside battery case, providing good contact. On the other hand - the whole battery is a bit wider now and comes in my laptop not so easy as before. So I don't count this as pro or con.
    Nice cells, but not for refilling laptop batteries. Next time I'll try something other.
  • Excellent battery size 18,650

    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.

    High capacity, High availability, performance, security protection for the electronics. Excellent for high power LED lamps, and in areas where long hours of power to customer.
    Ordered three pairs. Already ordered a second set. Those who want high performance and safety, such Order. I have converted cordless hair clipper machine is put into it.
    If you need a quality long-term, high-capacity lithium battery. You can recommend this item to you. The delivery for this product was too fast.
  • .Great long lasting batteries

    posted by gearhounds

    Very cheap, long lasting cells. Recessed + nodes are great for me in my C2 Q5 which has been modified with a positive node spring. Great build quality, trouble free charging in sku 6105. Right to 4.2V then a clean stop. Just the right length for both my C2's.
    Make use of the measurements provided to insure that these will work in your lights. Been my experience that some popular lights such as Romisen's F4 will not take them, but can't say if their C2 clone will. If you don't feel like doing small mods like positive springs or positive solder contact points, you can spend 1 measley dollar more and get sku 5790 with a + node and the same quality.
    If your light takes 18650's, has a spring, raised + node, or you are handy, get these.
  • Excellent !!!!!
