KX3 Internal Batteries

It's time to initiate the three-month old KX3 into the great outside.

Recommendations for internal batteries appreciated.

Thanks.

I am a happy Eneloop customer; however, I'm also evaluating - and having a
productive time with - the Bonai brand from Amazon; specifically these.

Specs are advertised as 2800 mAH, low self discharge.

https://smile.amazon.com/gp/product/B00HZV9WTM/ - Same as above, but
cheaper.

Thanks for all the suggestions. Batteries ordered and on the way.

Much appreciated!

I've had good results in a number of applications with any of the
"pre-charged" NiMH.

"pre-charged" is the key. That's the normal marketing-speak for
low-self-discharge.

Eneloops are a very safe bet.

My Eneloop (non-pro) 1900mAh are still going strong almost three years later. The pros were not available yet when I purchased the KX3.

Re: KX3 Internal Batteries

I found that the standard Eneloops were better for my KX3 than the Eneloop
Pro. While the Eneloop Pro has a higher total capacity at lower rates of
discharge than the standard Eneloop, my samples had a higher internal
resistance than the standard Eneloop. That translated into a greater
voltage sag when operating at 10 watts with the Eneloop Pro cells compared
to the standard Eneloops, and so a shorter period of time before 5 watts
was maximum transmission power limit, and end of useful charge even at 5
watts came more quickly with the Pro cells compared to the standard cells.

I'm sorry I don't have more hard numbers to present, and perhaps I just had
a bad batch of Eneloop Pro cells, but it does make sense to me that in
order to get 20% more capacity at low discharge rates, internal resistance,
which is more critical at high discharge rates, might have to be sacrificed.
