I am type 1 diabetic and use an insulin pump which runs on a AA battery. Using a "standard" alkaline battery I get about 3 weeks of use before the "low battery" warning happens and I need to change it out.
I found an old Thunderbolt Magnum (Harbor Freight) rechargable AA in my junk drawer so I threw it on my Tenergy charger for 8 hours. In my insulin pump, the rechargeable battery lasted almost a month and a half before it needed changed.
I want to just keep using rechargeables since it lasted so much longer, but I want advice on which brand rechargeable AA batteries are best. Ideally I want 1500mAh+ capacity and a battery that won't lose a lot of charge if in storage a long time.
I have heard good things about Eneloop but they are a bit expensive. I have used Energizers in the past with no troubles but I still want some advice or other options before I pick up a set.
