Which appliance repair appliances do I need?

A reader writes: I have a 2001 Honda Odyssey and it is in excellent working order but I am not sure what I need to do to get it to work.

I also have a 2008 Nissan Skyline and it seems to be working great but I would like to know if it is possible to install a battery charger, charger, etc. I think I might just have to order one.

The battery is still in its original case but the charger is missing the fuse and the battery will not charge when the vehicle is off.

I would not want to be stuck with this.

Thanks.

The Honda Odyssey will be repaired in two weeks and will have a new battery and charger in it, said a spokesperson for Nissan.
