I got a free charger when I bought a new minn kota tmotor today. Here is a link to the charger

Can I use this to charge a trolling/deepcycle battery? Its a walmart battery (Everstart 24DC 6) and the guy there told me I could only charge it on the 2 amp setting or it would "burn it up". This charger says 5 amps.

None of this stuff makes any sense to me, any help is appreciated. If I could charge this battery faster without ruining it, it would make my day because it takes over 24 hours for it to charge on my old charger at the 2amp setting.
