Goal Zero Rechargeable AA Batteries for Guide 10 - 4-Pack

Energizer and Duracell make the same type but for less and with more mAh. Longevity unclear. Work well but Lion is really the way to go.

No complaints here. I mean, you just them and you recharge them. We have them in some lights that don't get used but a few minutes a day and they last a few months between recharges.

I bought a 2nd set of GoalZero batteries for back-up for week-long remote canoe camping in case of inclement weather in which the solar panel couldn't collect enough sunlight for a couple of days. I use it with my Goal10 charger and Nomad solar panel. I've used my 1st set of batteries for 2 summers - they are AWESOME. They hold a charge better than other brands, and recharge quickly. I highly recommend leaving home with all batteries fully charged via A/C or USB.

not much to say, they can recharge. like every recharable battery, they don't get as much power or hold a charge as long as non rechargable batteries. no better than say energizer, but no worse either.

These last a long time; they're not like your old school rechargeables that die in an hour. I use it with the Guide 10 and carry it in my bag just to charge my iPhone if I need it. I haven't tried Eneloops but I've heard that these last about the same times.

These worked well for me to keep my iPhone going all day (literally) in GPS mode.

They last a decent amount of time with a full charge, can last a full day in my GPS and quite a while longer in my head lamps. I got 2 sets of the AA and 2 sets of the AAA and it seems to suit me well for all of my battery needs in the back country.

The batteries are great. I haven't used them in any other system than the Goal Zero Guide 10, which I take everywhere with me. Extra batteries are a great way to turn the Guide 10 into an extra unit at a low price.
