depends how much you use them...mine will usually last about 2 weeks..maybe a little less...i recommend that you purchase rechargeable batteries as it will save you dearly in the end!
My mom has tons... But... I'm just saying.. I play ALOT.. like I played about... 10 hours last night.... That's becausr I had a friend over... On average I'll probably play 4 hours a day... How long will they last then?
they will last along time if ur only playing 4 hours a day...i play somewhere around 10 hours everyday when i get the chance...so maybe they will last you on avg say a month?...give or take a few days/week
