Hello,
We are designing an Emergency LED luminaire, and need to evaluate the battery technologies in terms of cost per mA.hr, size of battery, Cost of charger circuitry given that we have 18 hours in which to recharge, and battery lifetime.
(Emergency Luminaire must suppy 5W for 3 hours.)
We have only had info from SAFT so far, and to be honest, we know of no major competitors to SAFT. Do you know of any?
Also we are having difficulty getting pricing info.
We wish to evaluate and compare..
NiCd
NiMH
Li ion
Li polymer
i've read lots of articles but none seem that concise, wikipeida seems best but we cannot get the comparison from there.
