trickle charging the battery

[staneee]

I've a 4 amp battery charger that has two setting (slow/fast)
I'm I safe to connect this to the car jump terminals or is the ampage to high?
I'd like to trickle charge the battery for half a day or overnight.

I have had success trickle charging my battery through the terminals under the hood on low with a 4 amp charger. My X5 was a 3.0 2002 model.

I've also done the same. 06 3.0 x5.

i use the battery tender all the time on the jumper points in the engine bay. takes 24hrs or so to get a good charge. works great
