Test/review of GTL LS14500 2300mAh (Purple)

GTL LS14500 2300mAh (Purple)
Official specifications:

  • Capacity: 2300mAh
  • Voltage: 3.7V
  • Color: Purple
  • Size: 14 × 50mm

GTL a brand with very high capacity specifications on their batteries, the problem is actual performance.

Up to 1A these cells can deliver 300mAh with not too bad matching between the cells
I dropped the temp curves, these cells stay fairly cool.
The capacity is about half compared to good 14500 cells and good cells can deliver 3A, not only 1A.
They are useable, but with the low capacity and current ability I will rate them bad (I wonder if they are produced as cheap cells).

I have some of these, they are good for AA lights that don’t have LVP to get a bit more output. Although they sure won’t last long!

I have one of those lying around, begifted from a friend with a cheapo SK68.

Observing the charger dV, I had predicted above 200mΩ of internal resistance. Seems I was on track. 

By the way, scrapping the “2” off the wrap turns it out into a honest battery. Smile

The human mind, and its programming, is at the forefront of a particular battle of The Light vs evil dark forces. Nearly every human being on this beautiful planet “Earth” has some sort of negative mind programming in its mind. And you better take care of your mind programming, or someone else will in this wicked world.
