Starting Batteries
Cranking or Starting battery, this simply means the battery has capacity when correctly sized to start an engine. A larger engine requires a larger battery and the extra volume within the battery gives more surface area for the plates to create a larger chemical reaction to produce more current to start your vehicle/engine.
AGM batteries are designed to have a higher energy density and therefore a higher cranking output. Many times a smaller AGM battery can easily start a vehicle that might have typically had a much larger battery in it. Lithium batteries have a higher energy density again and while there are other considerations with a different type of chemistry they are even smaller and much lighter than AGM batteries because they don't contain a heavy metal (lead).

High Power Output in a Six-Pack Case
The Optima range of batteries is a perfect replacement where high cranking power is required over the standard wet-cell. They provide sealed maintenance-free convenience with high CCA in a small form factor suited to engine start of automotive and marine applications. With multiple terminal options and reverse posts and side post options, there's a little something for everyone.
Optima 34M had dual posts on top for automotive SAE and Stud.
This cranking battery has the same CCA as all other Starting batteries in the Optima 34 group size.
Key Benefits
- Both dual-purpose and starting applications available
- Up to 3x more recharges than other marine batteries
- More than 15 times the vibration resistance
- Spill-proof
- Mountable in virtually any position
- Maintenance-free
- Optimal starting power (dual purpose and starting applications available)
- Works well as a boat battery or RV battery
