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).

This battery was the NZ Super Tourers category specified race battery and is the entry point for V8 vehicles or street driven race cars 2.0L upwards.
Typically the largest battery required for rally cars, its a Honda Jetski replacement battery being a U1 size replacement (when turned on its side). It's also the same size as mobility scooter batteries 24-28Ah so if you needed high power output for short duration hill-climbing this should be considered.
PC925MJT includes metal jacket and terminals.

28Ah @ 20hr rate - that's 1.4A for 20 hours until the battery voltage is 10.5V
27Ah @ 10hr rate - that's 2.7A for 10 hours until the battery voltage is 10.5V
Reserve Capacity 48 minutes at 25A discharge
Terminal Features include:
Encapsulated M6 bolt fastened using an M5 Allen key
Coarse thread Heli-coil inserts and bolt supplied so you can fasten large eyelets to the top of the terminal like a marine or dual-purpose terminal
Terminals are removable with an Allen key to reduce battery height and they use an M6 bolt insert.
