Accept no substitutes. What you want is a battery maintainer, like the Deltran Battery Tender. With these you can leave the charger on whenever the car is parked, even during prolonged storage, without damage to the battery. They will bring a battery from dead to charged in about 2 days if you need that function too. Normal chargers will simply continue to charge and the battery will loose fluid. The Battery Tender is available from Roundel advertisers (Imparts for one) and the prices seem to range from $45 to $60 depending on who's selling it with dealer cost just a shade under $40. The only system that works as well is the BMW charger for motorcycles which comes with a plug to fit the bike accessory socket and run a low amp charge which shuts off upon completion and then recycles as needed. A bit more money but so cool for the bikes. If you have trouble finding the Tender locally, try a bike shop, BMW or otherwise.
