Hi all, hope someone might point me in the right direction.
i work away from home for 4 weeks at a time and i have noticed that when i get back my car is getting harder to start.
sounds like my battery doesn't like me been away for so long (either do i for that matter..lol )

so i am in need of a battery charger/maintenance to keep my battery alive.
so i have been looking around but not sure what way to go.
solar is no go as the panel would be knocked off by some one to easily.

so i need a plug in type..
and can i leave the battery connected to the car during this process?

any ideas would be greatfull


thanx in advance
