Mobility battery Deka GC45 255Ah 6V
The 6 V, 255 Ah Deka GC45 with conventional lead-acid technology is the standard replacement for power wheelchairs, mobility scooters and light electric vehicles. It replaces the original battery without adaptation in power wheelchairs and mobility scooters with a 260 × 181 × 301 mm format: same 255 Ah capacity.
- Conventional lead-acid: the most proven and economical technology.
- Designed to be discharged and recharged daily without losing capacity.
- Thousands of useful cycles over its lifetime.
- Standard replacement format for wheelchairs and scooters.
What the Deka GC45 is for
With 255 Ah, the Deka GC45 offers the daily range that power wheelchairs, mobility scooters and light electric vehicles need, with a sealed construction that is safe indoors. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 34.93 kg.
Will it fit your current battery tray?
In terms of format, the Deka GC45 measures 260 × 181 × 301 mm (length × width × height) and weighs 34.93 kg. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.
Deka: the maker behind the GC45
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 GC45
Deka builds the GC45 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.
The conventional lead-acid battery remains the most widespread technology thanks to its balance of capacity, cranking current and price. Well maintained and kept charged, it offers years of reliable service in vehicles without Start-Stop.
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 GC45 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.
Delivery times and returns
Orders placed before 6:00 pm with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have 14 days to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

Frequently asked questions
How do I change this battery step by step?
In most devices it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
What is the service life of the GC45 model?
Expected lifespan of the Deka GC45 is 4 to 6 years in regular device use without Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.
What are the dimensions of the Deka GC45 battery?
Dimensions (length × width × height) are 260×181×302 mm — also written as 260x181x302 mm — following the European DIN standard. Always measure the space in your device before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
Which interchangeable batteries are there for this one?
Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop devices. See the "Equivalents" section to view recommended options at the same performance level.
