This battery is designed for 4.35 volt and need a special charger to get the full capacity.

Looking very careful on the shrink wrap, it is possible to see the battery type.

I am not very impressed with the capacity, but the voltage is high compared to 4.2 volt batteries.

Test at 4.3 volt charge

Reducing the charge voltage to 4.3 volt, looses about 120mAh in capacity.

Test at 4.2 volt charge

At 4.2 volt, the capacity is down with about 360mAh and the voltage advantage is gone.

Conclusion

Being a Sanyo battery it is very good, but I wonder about the low capacity, it might be due to age (If I read the datacode correct the battery is from 2010).

Thanks for the review HKJ. I was curious about these cells.
I like the UR18650ZT cells. These ZTAs offer no capacity advantage and the voltage advantage is already there in the ZT.

Welcome the night.

Thanks for the review HKJ.
The capacity surprised me, but if it really is from 2010 then I guess it’s expected.
Haven’t seen a 4.35 volt cell before so thanks, this was interesting!

I just finished testing 1 year old laptop battery with cells also 1 year old:

2456mAh from 4,2V

Result is obvious: These batteries are overrated.

Not bad, you got more capacity than I got in this test.
