I’ve been actually moving away from AA and AAA lithium’s as my collection of Eneloops expands. My Surefire lights take only lithiums and I tend to use them for emergency lights only, not for everyday things. As lithium batts are fairly expensive be it the Surefire batts or just lithium in AA or AAA.

I just picked up a couple more packs of Eneloops at Costco the other day and if you’re a member they are $4 off at the register now. Package includes a charger, 8-AA and 4 AAA for $21.95. These new Eneloops have been improved over the older white colored version in they hold a charge for up to 3 years and take a charge up to 1,500 times and are good down to I believe -20 . From everything I’ve read there isn’t much chance of leakage with the Eneloops.

However, lithium’s still have a place in my pack as they are very light in weight compared to the Eneloops.

I carry extra batts for the Surefire lights in the carrier's made by Surefire. The AAA and AA go in film canisters, prescription bottles or those zip lock's made for pills. Which method depends on if weight is a factor.

And I still keep plenty of regular copper tops on hand for a power outage to run lanterns, radio's etc. as they are fairly inexpensive to keep on hand. I've had power outages for 9 days here from storms. However, never leave them in devices as they will leak.
