Deep Cycle VS High Cycle Batteries

Cranking Batteries:

• Can supply large current
• Can accept large charge current (i.e. can be charged quickly)
• Do not like to be discharged deeply (life is shortened)
• Mostly automotive batteries.

Deep Cycle Batteries:

• More suited to deep discharging (more cycles)
• Can not supply very high current (not suited to winching),made for low current draw over a long period
• Can not be charged as quickly.
• Typically should not be discharged more than about 50%, i.e. don’t go below 50% state of charge

High Cycle Batteries:

• Used for standby (ups)
• Somewhere in between Cranking and Deep Cycle Batteries
• Can supply more current than Deep Cycle
• Can be recharged more quickly than Deep Cycle
• Typically should not be discharged more than about 25%, i.e. don’t go below 75% state of charge.
• Withstand deep discharging (up to 50% capacity) better than Cranking batteries
• Good option to run some auxiliary equipment to relieve the load on the deep cycle battery.
