Keeppower 14500 800mAh (Black)



Official specifications:

• 14500 800mAh Protected Rechargeable Battery
• Min Capacity: 750mAh
• Typical Capacity: 800mAh
• Normal Voltage: 3.7V
• Quality Lithium Ion rechargeable cell
• In Built Safety Circuitry
• Maximum capacity and reliability
• High Discharge Rate (Max 2C)
• Protection Circuit (Against overcharge, over discharge, over current and short-circuit.)

The battery has no problem keeping the rated capacity, even the 2A trace is very close to rated capacity.















Conclusion

There is not much to say about this battery, with a Sanyo cell inside and a protection at around 3A, I will call it a very good battery.



Notes and links

Keeppower is a OEM manufacturer, i.e. many of the batteries they produce is sold with other names on them.

The batteries was supplied by Keeppower for review.

i wish they sold through retail, great review!

They sound very reliable. I'd like to buy some, but I guess they're not for sale under the Keeppower name? I guess I'm not understanding why they provide cells for evaluation... that perhaps are only available under one of the other names they produce for?

It is old good Sanyo. Most of their cells are top performers.

Thank you HKJ

Great review thanks, i sent a message to the ebayer who sells the Keeppower 18650's
in the hope they maybe were going to sell the 14500's, but they replied saying no.

It's such a tease to submit these for review and then not sell them.

Great minds. I asked about the 16340 cells, and was told the same thing.

I know they're unprotected, but Orbtronics is selling the Sanyo 840 mHa 14500 cells for $8 a pop and if you buy 4, you get 10% off and shipping is gratis.

They work well in my single cell Xeno E03.

Try asking keeppower about it (I do not know what the answer will be).
