Test / Review: EagleTac 14500 750mAh (Black)

EagleTac 14500 750mAh (Black)



Official specifications:

  • 750mAh IC PROTECTED Rechargeable Cell (4.2V hot off charger)
  • Measures only 51.1mm in height (+/-0.1mm) and 14.4mm in width
  • IC protected for a) over-charge, b) over-discharge, c) short circuit, d) current overflow of 3A+
  • True protrude top design, fits all flashlights
  • High discharge rate 3A+
  • Nominal voltage: 3.7V, charge up to 4.2V, use CC/CV charger to charge
  • Reinforced steel plate bottom, highly efficient protective PCB design
  • Packaged in individual box and anti-static bag





This battery has nearly the same size as a AA battery (It is slightly longer), but can only be used in equipment designed for LiIon batteries, due to the much higher voltage.









On one of the test batteries the protection PCB was slightly crooked.



This battery has more capacity than specified, even at 1A load.











The protection is at 5.4 ampere, this is a bit high in my opinion.





Conclusion

With the good capacity, a good performace and a construction with a metal plate at the bottom I like these batteries, but I do not like the crooked protection PCB and that the cells are from an unspecified supplier
I will call this battery acceptable.

Maybe Eagtac cells are not the very best on the market .. but at least we know the brand behind it and can contact them on the phone (USA). Their service is great!

Thanks a million for these valuable contributions to your site!! Please let some flashlight reviews follow. You could tell how popular/desired flashlight reviews are .. as long as the flashlight is a desirable product!

Eagtac flashlights are quite popular..

thanks for doing this.

I like 14500s, although I'm always tempted to overwork them.

Is there a special reason you didn't test at 3A? If they hung in there at 600mah (which I doubt) I'd probably buy some.

With 750mAm batteries the maximum is current draw will be around 1.5 ampere, the rated 3A is very high for this battery. For that reason I has decided to use 2A as my maximum, except for high current batteries.

that makes sense. i was surprised by their rating.

The EagleTac 18650s use Panasonic cells, are we sure that these do not?

Yes, if you look at the 18650 battery, EagleTac specify "Cell made in Japen" on the battery, they do not do that on this battery.

Ok, I was going to buy a pair of these for $12.99 shipped but thinking I may just buy a single AW 14500 since I bet that is a Panasonic cell. Any other 14500 cells that you would recommend HKJ?

I am not so sure about that, it is probably also a China cell

Not at the current time.

So that EagleTac is actually the only 14500 cell you would recommend?

I would also recommend AW, that battery has proven that it works. AW is probably very careful with getting a good quality cell.

When I have tested some more I might also add a Sanyo based 14500 battery to the recommended list.

Ok, thanks. I just don’t want to end up with a firecracker, lol.
