what do you guys think of a battery charger if your car spend most of the week now on the garage.

would it hurt the battery?

 

I have a trickle charger from BMW and it works great! It shouldn't hurt your battery.

 

do you have it running all day and night? also is there a difference between the one that conects to the socket and has an on-board microchip to monitor and regulate the charge? also from BMW

 

I currently don't use it that much, But when i do it stays plugged until i get back from my trip. When you say socket do you mean the cigarette lighter socket ( Those chargers do not work on E60's ) you need the one that plugs in to the electrical outlet.

 

I was checking on BMWusa and they have one the one that I was asking is the one that goes to the wall outlet and insert the adapter into your BMW?s electronic socket

thats the product link maybe you can take a look at it..

 

Ooh Ok i see. The one i have connects to the wall outlet and has 2 clips that connect to the battery terminal under the hood.

 

It's the same as mine but instead of having the socket plug I have two clips that connect to the battery terminal under the hood.

 

yes I am looking at yours also, these one seems more practical .. maybe samething I will ask the dealer if there is any diference..

 

griotsgarage.com has a battery manager that looks very similar to the bmw one. It''s on sale for $39.99 (battery manager II). I've had the original battery manager on a seldom used convertible for quite a while with no problems. Griot's garage tends to be expensive, but the stuff is very good and has a lifetime warranty as I recall.
