How long does a deep-cycle battery last?

It depends on the technology: flooded deep cycle gives 500-800 cycles at 50% DoD (3-5 years), deep-cycle AGM 800-1,200 cycles (5-7 years), and LiFePO4 lithium 2,000-5,000 cycles (10+ years).

Can I use a starter battery instead of a cyclic one?

Not advisable: starter batteries degrade quickly if discharged below 80%, whereas a cyclic battery is specifically built for deep, repeated discharge.

What's the difference between deep-cycle AGM and GEL?

AGM tolerates higher charge currents and is usually cheaper; GEL copes better with high temperatures and very deep cycles, though it charges more slowly.

Is a cyclic battery compatible with any caravan, boat or solar installation?

It must match the system's voltage (12V, 24V or series banks) and minimum capacity (Ah); check the specific category for your application for recommended references.

How deep can a cyclic battery be discharged without damage?

Lead-acid tolerates up to 50-80% DoD depending on technology without significantly shortening its life; LiFePO4 lithium admits 100% DoD with no penalty.

Cyclic Batteries

Cyclic or deep-cycle batteries are designed to discharge repeatedly to 50-80% of their capacity without sulphating — the exact opposite of a starter battery. Typical uses include caravan/motorhome, marine service power, solar PV installations, UPS/backup power, mobility scooters and wheelchairs, industrial traction and golf buggies.

Three technologies dominate the range: flooded deep-cycle lead-acid (thick plates), sealed AGM deep cycle and premium LiFePO4 lithium, each suited to a different budget and duty cycle.

How to choose the right cyclic battery

Cyclic batteries are rated by cycles at X% DoD (Depth of Discharge). "1,200 cycles at 50% DoD" means 1,200 discharge-recharge cycles to 50% before capacity drops to 80% of rated. Lead-acid rule: never below 50%. LiFePO4 admits 100% DoD with no penalty.
