I'm preparing to buy new Tenergy D rechargeable batteries, 8,000 mAh - 18 of them for my lanterns and fans. Rechargeable 1,000 times and keep the charge 70% after two years. No memory effect.

Maybe you all know the rechargeables you get at regular stores, Energizer, RayoVac, Duracell, have been knocked down in power - the body is the size of a D, but there is AA power inside. Maybe that's okay for an unimportant item but in an emergency situation I want my lanterns and fans to keep going, not crapping out in a short time.

I'm also buying a 20 watt solar panel with smart charger that plugs into solar panel for recharging these Ds in 4-5 hours. AAs take 3 hours, so maybe Ds will be “done” in that 4-5 hour time.

My electrical engineer relative came for Thanksgiving and he checked my old rechargeables and only three of those could be saved.

I've already bought bunches of Sanyo new AAs that charge 1,500 times and keep their charge a long time - at 75% strength after three years. No memory effect.

Just moments ago I converted my Schlitz Long Neck bottle flashlight into an LED flashlight.

I used an LED drop-in and D battery adapters for AA Tenergy rechargeables.

I am now "prepped" as they say with a truly camouflaged flashlight with a much longer battery life.

When buying rechargeables, remember that the LSD versions are the new break through and is what most of us were looking for, and all of us were looking for, for some applications, but if you have something that you are going to use heavily, and frequently, and will be recharging every month or two anyway, then you may want to use the non-LSD batteris for that, because you can get higher mAh numbers, for instance 2700 mAh AAs instead of 2000s mAh.

People who use their cameras constantly for instance.
