## Description

**Deka GEL batteries** are East Penn's sealed, maintenance-free deep cycle gel batteries, developed for power wheelchairs, mobility scooters and stationary energy. The range covers 32 to 225 Ah.
The gelified electrolyte withstands deep daily discharges, making them the preferred **GEL mobility battery** for intensive users: more life cycles than an equivalent AGM, spill-proof, and equally suited as a deep cycle battery for energy systems.

## Deka GEL: the deep cycle battery for daily mobility use

In a **Deka GEL** battery the electrolyte is gelified with silica: there is no free liquid, the battery is sealed for life and it copes exceptionally well with repeated deep discharge and heat. That is why GEL technology is the pick when a power wheelchair or mobility scooter is used every day and a large share of the charge is drained.

### Deka GEL models and applications

- **Deka 8GU1** (32 Ah): GEL battery for small mobility scooters.
- **Deka 8G27** (89 Ah): standard power wheelchair.
- **Deka 8G31** (97.6 Ah): bariatric chair and higher-demand equipment.
- **Deka 8G8D** (225 Ah): stationary energy and battery banks.

### How to choose your GEL mobility battery

Always replace with the same capacity (Ah) and dimensions as the original battery; 24 V equipment runs two 12 V batteries in series, best renewed as a pair. Compare models, sizes and prices in our [battery comparator](/gb/comparator).

## Frequently asked questions about Deka GEL batteries

### **What is the difference between a GEL and an AGM wheelchair battery?**

GEL uses a gelified electrolyte and endures more deep discharge cycles, ideal for intensive daily use; AGM is cheaper and delivers more current, suited to moderate use.

### **How long does a Deka GEL battery last in mobility use?**

It depends on discharge depth and charging: with a full recharge after each use and a GEL-profile charger, a gel battery usually outlasts an equivalent AGM in daily use.

### **Do gel batteries need a special charger?**

Yes. They require a GEL-profile charger with controlled charge voltage; an unsuitable charger dries out the gel and shortens battery life.

### **Which Deka GEL fits my wheelchair or scooter?**

As a guide: 8GU1 (32 Ah) for a small scooter, 8G27 (89 Ah) for a standard chair, 8G31 (97.6 Ah) for a bariatric chair and 8G8D (225 Ah) for stationary energy.
