I have a portable battery pack that uses a 15V DC pod to charge it. That

Can I use my car battery charger by hooking it up to the clamps on the battery pack?

If so, I have these specs and these choices. Which should I use?

Battery Pack: 12V/15A

Charger Choices:
6 Amp, Fast Charge, Automotive/Light Truck
4 Amp, Medium Charge, Automotive
2 Amp, Trickle Charge, Lawn Tractor/Motorcycle/ATV

Thanks!

Typically use 1/10 capacity for 10 hours. 1.5-2 amp charge. I don't know if
the charger just keeps putting out or shuts own.

GENERALLY they put out 2 amps maximum, and taper down as the voltage
comes up.. Some taper down enough to avoid boiling the battery
(usually referred to as float charge) while many simple "trickle
chargers" have no regulation at all.
