What type charger do you use?
I use a D sized brand called Tenergy. I get the 10,000mah ones and they run my boxes for as long (or longer) than Alkaline batteries did. It takes a while to charge them and they're the same weight as regular D's but I like them.
They're NiMH so they do not suffer memory like the older NiCads did.
I'll have to check when I get home. I know the batteries and charger came as a kit through their website..
Found it. Thank you very much.
NP. It's around 100 bucks or so for 8 or more batteries with a charger but when you factor in that you can recharge these over 500 times without any noticeable drop in performance and up to 1000 times before they expire, they are for sure the best option over throw away Alkaline. If you go this rout get the white 10,000mah batteries. The blue ones I'm not sure about their abilities or quality.

If you get this combo I can assure you will be happy. These run my C100F and JVC M90 all day long with reserve for the next day. The longest run time I've gotten was 14 hours per charge on these power hungry devices....which is better than what I got with Alkaline.
Also, this is a smart charger. They get hot if you don't deplete them between charges but supposedly you can toss them in and the charger will determine the current charge and go from there. If your power goes off while at work and comes back on it doesn't simply start all over and fry the cells. It'll pick up where it left off. It also shows you how topped off they are. If you run them down before charging they barely get warm from start to finish.
Like all NiMH batteries you will noticethey will improve in performance on the 3rd to 4th charge cycles and run longer than the initial 1st charge cycle. I'm not a sales person for Tenergy but I just can't say enough about their quality. I can let them sit in a box for months without worry of leakage and they don't lose but about 20% charge in 4 to 6 months from fully charged. Excellent batteries...
