Ordering on line was very easy & it was delivered within 2 days of purchase. I'll use Tayna again for my batteries. Thank you

Fitted To: Dodge Caliber 2lt Diesel 56

Smaller in size than the standard battery makes it easier to fit 2 of these under the seat with a bit of fiddling about, having connections on the front as well as top allows for uncrowded connection of extra leads for cables and Anderson socket in engine bay.
