[RE-wrenches] Battery reading materials

[Jesse Dahl]

Hello,

I have a client that just bought an off-grid home and is interested in learning more about batteries.  He is a very smart guy and a retired mine electrician.  Being older, he's not interested in sitting at a computer and reading, he wants something he can take into the fish house this winter and read. 

So any books I can point him to? I'd also print things off and binder them for him if I need so websites will work. 

Thanks as always!

Jesse
