What the Deka 8G31 is for
The Deka 8G31 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 31.07 kg.
Will it fit your current battery tray?
In terms of format, the Deka 8G31 measures 328 × 171 × 237 mm (length × width × height) and weighs 31.07 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.
What Deka does differently
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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
Technology inside the Deka 8G31
Deka builds the 8G31 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.
A GEL battery is the choice when cycle resistance and safety matter most: no gases, no liquid and thousands of partial discharges in its lifetime.
How to make it last longer
GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte. Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together.
Official warranty
The Deka 8G31 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.
When you get it and how to return it
Order before 6:00 pm with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have 14 days to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

Frequently asked questions
Is this battery GEL? What is the typical use?
Yes, GEL technology (97.6 Ah): a sealed lead-acid battery whose electrolyte is in gel form. Its maximum charge voltage is lower than an AGM's, so a GEL-specific smart charger is needed. Designed for cyclic use (solar installations, motorhomes, electric wheelchairs, motorcycles), it tolerates deep discharges very well.
What are the dimensions of the Deka 8G31 battery?
It measures 328×172×237 mm in length × width × height, with the terminals included in the height. Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close.
