I'm about to make an order on a new light and have added to my cart two AW RCR123 batteries of 750mah, are those some of the better ones to use, I know there are some that are 900mah and even higher is that false numbers?
Do you also own a DMM (digital multi-meter) if not- please consider buying one to monitor the conditions of your cells- Harbor Freight has a good DMM for like $4.99- well worth the investment. Take time to read up on the safe use of Li-Ion batts-plenty of info here in CPF.
I will be charging the RCR123 cells on the same $100+ digital mutli-chemestry charger I use on the lithium polymer batteries I use for my RC helicopter, I'm no stranger to lithium tech
Thanks for the concern though because these really are no laughing matter, plastic explosives.
I think somewhere here on the Forum, there is some info on AW's 750mAh cells, you'll have to search, or just look around a bit.
I charge my 16340/RCR123 cells at 250-400mA. I figure this is close to 0.5C for most cells, and there's really not that much advantage to, for example, a 1C rate. Due to the CV stage taking longer at a 1C charge rate, 0.5C doesn't take that much longer, and it's probably easier on the cells, anyway.
