Choosing Rechargeable Batteries for Lights
My current light setup uses AA and AAA batteries and I want to switch to using rechargeables to save money. I was turned onto the idea with the new "low discharge" batteries like the Sanyo Eneloops.
I got some for Christmas but they turned out to be the high capacity sort (2500 mah), but it looks like they're the kind that will lose their charge more quickly when left on the shelf or unused (they are Sony CycleEnergy High Capacity Batteries for the record).
So it seems like with the current battery technology you have to pick a tradeoff: higher capacity but more rapid self-discharge or a battery that retains its charge but doesn't have quite the same capacity.
I commute 10 miles a day for between 40 and 50 minutes in the saddle.
So the question is, as far as lighting on my bike go, which is the better choice? Using the higher capacity and just recharging them every weekend or the precharged type and not having to worry if they will lose their charge too soon.
Can anybody make an informed recommendation?
