suppose so , but if they do a better or battery than the impulse then it will be good because it takes 10 mins to charge the battery and you get 100,000 shots of it.True but i`d just forget to charge it! how long does it take to change a battery? 20secs. prob have to charge for 4or5 hours!
Will save on battery costs though i admit.
you will make £70/80back on just the battery depending how much you spend on atterys , ive already made my money back on my rechargeables on my vlocity
