Mighty Max Battery 12V AGM Group 26R Rechargeable SLA — 45Ah, 540 CCA, 80-Min RC

Built as a maintenance-free SLA (sealed lead acid) absorbed glass mat battery, the MM-G26R balances cold-start capability with longer reserve runtime and rugged construction. It’s designed for applications that need reliable cranking and sustained power delivery in a compact Group 26R package. The sealed AGM format eliminates spills and simplifies installation while the battery’s durable build tolerates vibration and varied temperatures.

How much starting power and runtime can I expect from this battery?

Expect strong starting performance in most light-duty gasoline engines with 540 cold cranking amps (CCA) for reliable ignition in cooler weather. The 80-minute reserve capacity (RC) gives extra runtime for electronics or accessories when the engine isn’t running. Together those specs mean balanced capability for both start-up and short-duration accessory loads.

• 540 CCA for dependable cold starts
• 45 Ah nominal capacity for typical accessory loads
• 80-minute reserve capacity for extended accessory runtime
• Sealed AGM chemistry supports high discharge and recovery

Is the MM-G26R durable enough for off-road or marine use?

The MM-G26R’s rugged construction and vibration-resistant design help it withstand shocks and rough conditions found off-road or in demanding mobile applications. Its sealed, spill-proof case prevents leakage and reduces maintenance compared with flooded lead-acid batteries. The battery is built and tested in an ISO-certified facility to meet CE safety and quality standards.

• Shock- and vibration-resistant construction
