I had to replace my regular rechargeable Energizer AA batteries after about 2 or 3 years since they didn't hold a charge too long anymore. I used the crap out of them though since I had 4 wavebirds. I bought some new ones and they work pretty damn good (usually last awhile before having to recharge them). My AAA that I bought a long time ago I never had to replace since I don't recharge them that often.
