The MCS, Nano Series sealed GEL battery, with 12V, 20Ah, 360CCA (Cold Cranking Amps). See fitments below.

The technology behind Nano-Gel batteries is basically a further development in AGM battery technology. Nano-Gel batteries are known to provide a long shelf life, a high capacity, good deep cycle resistance and more power. Based on AGM technology, but smaller nano sized particles in the electrolyte ultimately allowing plates to be placed closer together, without temperature issues. Simply put, the Nano-Gel batteries offer more capacity and power in a smaller housing.

• Better resistance to vibration and heat
• Better high current delivery (starting)
• Plated copper terminals
• Higher power density
• No gassing with safety valve
• Low self discharge
• Mounts in any position
• High charge voltage at around 20% of battery capacity
• Wide 20°C to +60°C temperature range
• Strong ABS housing
• Safe. Will not spill or leak, even when damaged
• Excellent life expectancy & reliability
