## Description

**Deka lead-acid batteries** (flooded, FLA) are East Penn's wet-cell batteries for traction and industry: golf carts, machinery and solar energy banks. Available in 6 V and 12 V, from 100 to 360 Ah.
Their thick-plate flooded construction delivers the best cost per amp-hour in deep cycling, which is why they remain the benchmark **6 V golf cart battery** and an economical stationary battery for solar and industrial installations with accessible maintenance.

## Deka lead-acid: traction and industry with East Penn reliability

**Deka flooded lead-acid** (FLA) batteries keep a liquid electrolyte and use thick plates designed for intensive cycling. In exchange for simple maintenance — checking levels and topping up with distilled water — they offer the lowest cost per amp-hour in deep cycle work, which is why they dominate in golf carts, machinery and industrial solar installations.

### Deka FLA models and applications

- **Deka GC15** (6 V, 225 Ah): standard golf cart battery.
- **Deka GC25** (6 V, 235 Ah): golf cart with extended range.
- **Deka L16** (6 V, 360 Ah): solar and industrial energy banks.
- **Deka 12L31** (12 V, 110 Ah): 12 V industrial applications.

### How to choose your traction battery

Golf cart packs combine several 6 V batteries in series: always replace the whole set with units of the same capacity and similar age so they work in balance. To compare capacity, dimensions and price across models, use our [battery comparator](/gb/comparator).

## Frequently asked questions about Deka lead-acid batteries

### **Which battery does a golf cart use?**

Usually 6 V deep cycle batteries such as the Deka GC15 or GC25, connected in series up to the vehicle voltage. Choose the same capacity and dimensions as the original pack.

### **What maintenance does a flooded battery need?**

Check the electrolyte level regularly and top up only with distilled water, keep terminals clean and charge in a ventilated space. With that basic care they achieve a long cycling life.

### **FLA or AGM/GEL for a solar installation?**

FLA, like the 360 Ah Deka L16, gives more capacity for less money if you can do regular maintenance; sealed AGM/GEL remove maintenance in exchange for a higher price.

### **Can I install a flooded battery on its side or in a closed space?**

No. As it contains liquid acid it must always work upright and in a ventilated place, because it releases gases during charging.
