## Description

Batteries built for long, repeated discharges: choose by application, voltage and capacity, and buy online with the shipping cost shown upfront.

A deep cycle battery is built to deliver steady power for hours and to be recharged over and over, not to crank an engine. Pick yours by the numbers: Ah capacity, discharge rate, cycle life, chemistry and case size.
Narrow the list by 6, 8 or 12 V and by AGM, GEL, flooded lead-acid or LiFePO4 to find the model that suits your equipment.

## How it differs from a starter battery

A starter battery packs many thin plates to release hundreds of amps for a few seconds. A cyclic battery uses thicker plates and denser active material, designed for slow, deep discharges. Put a car battery in a wheelchair or a camper and it will lose capacity within weeks.

## Reading the datasheet

- **Capacity and rate:** always compare at the same rate. A C20 figure (20-hour discharge) reads higher than a C5 one; for traction and mobility, C5 is closer to real use.
- **Cycles and depth of discharge:** cycle life is quoted at a given DoD (50 %, 80 %). The less you drain the battery, the more cycles you get.
- **Chemistry:** AGM is maintenance-free and handles high currents; GEL tolerates deep discharge and heat better; flooded gives plenty of cycles but needs topping up; LiFePO4 is light and lasts thousands of cycles with the right charge profile.
- **Size and terminals:** check length, width, height and terminal type (M6/M8 thread, faston, taper post).

## Choose by application

[Electric wheelchairs](https://bateriasonline.es/en/electric-wheelchair-batteries) and [mobility scooters](https://bateriasonline.es/en/mobility-scooter-batteries) usually run on 12 V blocks up to about 90 Ah. The leisure circuit of [motorhomes and caravans](https://bateriasonline.es/en/leisure-batteries-motorhome-caravan) calls for 12 V above 120 Ah. In an [off-grid solar system](https://bateriasonline.es/en/off-grid-solar-batteries), daily energy use and days of autonomy set the size.

## FAQ

### Can I use any charger on a deep cycle battery?

Better not. Each chemistry needs its own absorption and float voltage. Use a charger with an AGM, GEL or lithium curve to match the battery.

### Can I mix new and used batteries in a series bank?

Avoid it. The weakest unit limits the whole string and ends up over-discharged. Replace the full set with the same model.

### How should I store it over winter?

Fully charged, in a cool and dry place. Lead-acid batteries slowly self-discharge, so top them up every few weeks or leave them on a maintenance charger.
