Mobility battery Deka 8G40 40Ah 12V

The Deka 8G40 with GEL technology delivers 40 Ah at 12 V with the cycle life that power wheelchairs, mobility scooters and light electric vehicles demand. It measures 197 × 168 × 174 mm, the format sought by anyone replacing a 40 Ah battery in power wheelchairs and mobility scooters.

• Standard replacement format for wheelchairs and scooters.
• Thousands of useful cycles over its lifetime.
• Designed to be discharged and recharged daily without losing capacity.
• GEL technology: gelled electrolyte, fully sealed and maintenance-free.

What the Deka 8G40 is for

The Deka 8G40 is designed for power wheelchairs, mobility scooters and light electric vehicles. Wheelchairs and scooters normally use two identical batteries in series: replace them together. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 14.29 kg.

Technology inside the Deka 8G40

Deka builds the 8G40 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.

GEL technology fixes the acid in a solid gel. That removes maintenance and leaks and gives very long cycle life, in exchange for slightly slower recharging and lower peak current than an AGM.

Size, terminals and hold-down of the Deka 8G40

In terms of format, the Deka 8G40 measures 197 × 168 × 174 mm (length × width × height) and weighs 14.29 kg. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

Why choose Deka batteries

Deka (East Penn Manufacturing) is the largest single-site lead battery manufacturer in the United States, with full control of the process from lead recycling to the finished battery. We guarantee that every Deka arrives new, charged and with the manufacturer's full warranty.

How to make it last longer

Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity.

Warranty and coverage

The Deka 8G40 comes with the manufacturer's official warranty against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you.
