The precharged black top china cells are of the rayovac hybrid LSD series and are decent, but are not quite as good as the white top japanese precharged which are relabeled sanyo eneloops. If you haven't opened the block top ones you may consider trading them in for another package of white tops. I have a bunch of hybrids (black tops) and they work fine in most things but the white tops hold slightly higher voltage and are more sturdy as I have already damaged about 4-5 of the hybrids via cell reversal in sets.Ok, The black : Duracell rechargable/precharged AA/HR6? DX1500 NiMH
1,2V /2000mAH standard charge 200mA for 16h Made in China
The white: everything exactly the same, Made in Japan
It is safe, but if the light has high output I would strongly recommend against it because the black top and white top cells differ enough that you will have uneven discharge rates causing some to deplete faster than others which can easily lead to cell reversal when the weaker cells deplete. I would highly recommend using the black tops together and white tops together not mixing them at all.Thanks Lynx Arc, Unfortunaely i didn`t notice this until after i opened them and topped them off on the charger. Is it safe to use them together in the same light?
The black top LSD precharged are fine, just not as good as the white top ones. I have black top LSD cells in a lot of stuff and they work well.Lynx are the ones I posted okay to use or should I get the "white tops" mentioned above. Thanks
Of course they are "okay" to use; however they are not the low self-discharge batteries like eneloops. They are normal NiMH cells with slightly higher capacity than eneloops, but also a much lesser ability to hold onto their charge in storage. Do you want to stick that light in a drawer for months, or do you plan to use the light every day?Lynx are the ones I posted okay to use or should I get the "white tops" mentioned above. Thanks
Thanks again, I will follow your advice. Off to walmart for more white tops.
