Query: Cut cost and waste - Great!

I have used the energizer rechargeable for years. I love to go camping. Flash lights, mp3 players and other battery hungry devices can become very expensive to power. Not to mention the everyday items around the house like my wireless mouse and keyboard and tv remotes. I have used the same rechargables at least 100x. I never purached new batteries for tv remotes, mp3 players or flash lights. I use a Mag light which takes 3D battery. I use the slow charger. I have never had a problem.Two tips for using rechargeables:Use slow charge for longer life of battery in terms of number of recharges, and long life as for as maintining a charge.Use the fast charger (15 min quick charge) when you tv remote dies on you and you need batteries fast.If you have not made the switch to rechargable, do yourself a favor and switch.
