Ampac 110amp Leisure Battery is a deep cycle marine/leisure range of battery. These batteries are manufactured using heavy duty thicker plates, high density paste, anti-vibration support and glass matt separators. This feature extends battery life and durability.
Constructed with bound electrolyte in glass matt, the case is more than 15 times more vibration resistant than a conventional case. It provides better utilisation of cell volume and gives 250 cycles to 75% discharge.As with all batteries in the Ampac range, it comes with a carry handle.

[/FONT]A deep cycle battery is constructed differently than a cranking battery, with thicker and heavier plates and is designed to offer lower amps for a longer duration..... such as lights, radio, refrigerator, fan motors, etc.
A cranking battery[FONT=arial, sans-serif] has more yet thinner plates to give a fast voltage spike to crank an engine.
These are not intended to maintain high power output for long periods.
[/FONT]Your best scenario would be to install an MBSS along with two battery banks.
One bank for cranking (#1) , and one larger bank of Deep Cycles for your house loads (#2).
