have a 4c cell for about 10 year until I let a fellow guard use it and that be the last I have see of it just about a year ago . have a really nice rechargable flashlight at home but the end cap needle use to rechage it be broekn and this be the BEST flashlight replacement for it . recieve it in a timely manner 3 day of order and just in time for the weekend work shift . would highly recommend this flashlight as I do not know if I can order a new end cap for the rechargable , in which case it can still be use with regular battery but not as bright as with the battery it come with . these light can take a beating and still work . my lose old one be scracthe and betan but work when I need it to . buy this flashlight also for good self protection as a baton in most state be consider a deadly weapon and a maglight be not . but check you local law to make sure . do not quote I on the legality of the use of a maglight for protection make sure and look for yourself !!
