The Renewal batteries last just about as long as regular alkalines at first and then slowly degrade with
each recharge. The point here is that you can recharge them and save tons of money. Granted, it is still a
pain to have to charge them in the first place but it beats having to go out and buy new batteries every week
or so. What I do is buy one package of 4 AA batteries and rotate them so that I always have a charged set
ready to go. How long they last really depends on how you use your OmniGo.
Best of Luck
