Costco! Duracell 4 AMP 12 and 6 volt Battery Charger + Maintainer $32 (Instant Savings – Normally $44). There are other smart 12 / 6 volt battery charger and maintainer online : . The interesting thing about this Duracell battery charger and maintainer is that it can charge 4A ( 12V lead acid, 12V Li-ion (LiFEPO4) or 1 A ( 6V lead acid ). It is also IP65 water resistant.

I bought a Battery Tender from Costco last year for my AGM and 12 volt batteries. Overall its good to have one if you have multiple cars or recreational vehicles and you do not want the battery to discharge and get damaged. Otherwise I normally disconnect the car battery if i know the car will not be used for a few weeks to prevent drain.

I use these to keep my other cars which are parked for a long period of time. For my Honda Accord and Dodge Cargo Van, I connect the leave the 3 amp Battery Tender on over the weekend and swap cars every week.  This keeps the cars 12 volt battery from failing and the cars are ready to drive if needed.
