i use high end rechargeables in mine and just charge them when i need too. i can go about a year or 2 without recharging them but my newest i wired as an 18 volt and its been about 6 months so far. i hate buying batteries or having to run out to get them when i want to play thats why i use rechargables.Do all of you actually change batteries or do you use rechargable ones? is there any difference(in relation to the instrument)?
