So an alternative to the eneloop/panasonic XX pro 2500mAh cells then if they are LSD ?

What is the price of them compared to the XX cells ?

Thanks again HKJ!

Good to see their performance in a good review!

Oh, and 2 little things. Their capacity is 2400mAh min.. Not typical, as most other brands overseas do. Even standard eneloop shows 2000mah overseas while they show 1900mah here.

Eneloop, Toshiba etc bought in Japan always show Minimum capacity.

So that might be useful to know when people look for new nimh batteries.

So 2400mah in Japan might be considered 2500mah overseas, mainly because of difference in what kind of rating they use!

Not saying it is a bad battery. Nor not purchased in Japan. The bottom battery in the group of three just above the first graph says” Made in China”.

Yep?

Did you mean purchased in Japan or manufactured in Japan ? That is my only question.
