my husband and I buy we first maglite almost two year ago , and its still work like its new . he use it nightly at work . he can get about a week to two week usuage out of it before he have to charge it . we buy the second for home use because we get tire of buy battery for the small maglite you get from wal-mart . we love we new rechargable as much as the old one . I buy it about a month ago and use it about once a week . I havent have to charge it once . the only complaint I have have about maglite be that the button on the first one have fall off but it be still work fine other then that .
