I run a JVC Kaboom box at outdoor volleyball tournaments. The unit can accept 10 D cell batteries and can them chew up in one day. I'd need to carry a spare set of 10 D cells. Spent alkaline cells would go in the trash. A set of good rechargeables and chargers would run near $200. Instead I used a single SPV20. I think it has ~20 hours of capacity for my device. I charge with a 15 amp marine smart charger. The charger never seems to indicate a charged state, so I simply disconnect after a few hours, to avoid overcharging. I realize repeated undercharging can also degrade performance, but the basic problem is that it's difficult to read the charge state of this type of battery. I would certainly like to see a built-in LCD charge indicator, for both charge and discharge. I happen to have a sturdy cloth carrying case with strap, but it is rather a pain to carry the heavy battery around. By the way, I had to solder a custom 12VDC supply cord for the Kaboom.
