I had plenty of batteries and a back up of rechargeables with a solar charge for charging little things like cell phones, GPS, batteries, etc.

The fairly cheap solar chargers are something most people don't think about. I have several, one dedicated to keeping the batteries on my bass boat on trickle charge during the winter. They work great.

I have two chargers. A small for backwoods hiking and a larger one, that could be used for hiking and would be annoying to pack around but it does work and I will have it available should the need arise.
