Looking into buying a small solar generator as part of the survival plan (and also just general family camping). This got me thinking about rechargeable batteries of the AAA, AA, C and D variety. So I started doing some research. Harbor Freight has had good reviews on their NiMH batteries and I just got a 20% off coupon (actually several of them) so I might invest in some of them and perhaps a good charger. I also saw somewhere (maybe youtube) someone suggest the solar powered lights you'd buy for the sidewalk/garden. The kind that comes with the spike to stick in the ground and already has a AA in it. The suggestion was that it would be a good single charger for the AA if the LED was removed to stop any draw on it. Has anyone tried this? How long do you think it would take and can any rechargeable AA by put into it to recharge? Good idea as a back up to a regular charger or a crap idea? Thoughts welcome and thank you.
