Designed for power wheelchairs, mobility scooters and light electric vehicles, the Deka GC15DT offers 230 Ah of deep-cycle capacity with conventional lead-acid technology. Its 260 × 180 × 275 mm make it the exact replacement for the 230 Ah battery fitted as standard to many power wheelchairs and mobility scooters.

  • Approved for air and sea transport (VRLA).
  • No maintenance, no water top-ups.
  • Sealed AGM/GEL: safe indoors and in transport.
  • Good balance of capacity, cranking power and price.

What the Deka GC15DT is for

With 230 Ah, the Deka GC15DT 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 28.58 kg.

Technology inside the Deka GC15DT

Within the Deka catalogue, the GC15DT is the 230 Ah model designed for this application.

In a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use.

Dimensions, polarity and mounting

It has external dimensions of 260 × 180 × 275 mm and weighs 28.58 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.

Deka: the maker behind the GC15DT

Deka batteries are known for their robust construction and consistent quality in automotive, marine, leisure and industrial use. All the Deka batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

Usage and maintenance tips

On batteries with filler caps, check the electrolyte level and top up only with distilled water. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity.

Manufacturer's warranty

The Deka GC15DT 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

Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

Frequently asked questions

How do I fit the GC15DT model in my device?

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 GC15DT model?

Expected lifespan of the Deka GC15DT 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 measurements of the GC15DT model?

Dimensions (length × width × height) are 260×180×276 mm — also written as 260x180x276 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.

What are the equivalents of the GC15DT model?

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.
