Test / Review: PALight BR18650 3000mAh (Yellow)

PALight BR18650 3000mAh (Yellow)



Official specifications:

  • Operating voltage: 3.70
  • Capacity: 3000mAh
  • Ultra-high capacity and premium built quality
  • Protected to avoid over-charged or over-discharged




This battery only has about 66% of rated capacity and cannot deliver high current.











The two batteries has slightly different capacity and can only sustain a 3A load for some time.









The battery can only sustain a 10 watt load for a short time, then the over current protection trips.



The over current protection trips at a very low value.





Conclusion

The battery has much less capacity than stated on the cell and can only be used with light loads.
The batteries can barely rate as acceptable for a cheap battery.

Thanks for the review HKJ.

As I have written before, I plan on adding a few of the cheaper brands to the test. It will just be a very limited sample of the cheap batteries, even if I wanted, I do not believe that I could keep up with the new discount brands introduced.

Thanks, HKJ: telling it like it is!

Thanks again HKJ!

Thanks a lot for another detailed review! Frontpage’d and Sticky’d.

Thank you. You have a high degree of integrity HKJ. :slight_smile:

I received uprotected Palight, 3000mAh, with some good Palight flashlight (C9 gray with R5) from Dinodirect

Batteries were junk, they had several hunderds mAg capacity, felt very very light in hand.

More cheap batteries test please!!! :smiley:

HKJ : Thank You for another money saving review.

Please supply some links to batteries/shops, that you want tested, then I will consider it. Remember that it takes between 1 and 2 months from I order a battery, until it is tested (Time might be longer, if my pile of batteries grows again).
