i have been switchin over to them rechargeble batteries i use the energizer ones in all my lights and i used a set in my fuji camers and they do pretty good the only thing is they are only good for a month or just a bit over a month but they are worth it because you can recharge them over and over. i have a car charger and a home charger for them .i useAA/AAA/D sizeenergizerrechargable batteries. just when you buy them go with the highest nuber thats on the side of the battery i think mine are the highest power ones and they say 2450 i think.</p>
