## Description

**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.

## Frequently asked questions about cyclic batteries

### **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.
