### What the Deka 8G27 is for

The Deka 8G27 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 28.12 kg.

### Dimensions, polarity and mounting

It has external dimensions of 326 × 167 × 241 mm and weighs 28.12 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.

### Technology inside the Deka 8G27

Deka builds the 8G27 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.
In a GEL battery the electrolyte is gelled with silica: it is fully sealed, cannot spill and tolerates deep discharge very well. It is the preferred technology in electric mobility, marine service and heavy-cycling applications.

### Deka: the maker behind the 8G27

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.

### Official warranty

The Deka 8G27 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.

### Care and maintenance

Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together. GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte.

### Delivery times and returns

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

### Is the 8G27 model a gel battery? Where is it used?

Yes, this model is a GEL battery: sealed lead-acid with the electrolyte in gel form. With very good deep-discharge tolerance, it is ideal for cyclic use: solar, motorhomes, electric wheelchairs and motorcycles. It needs a GEL-specific smart charger: its maximum charge voltage is lower than that of an AGM.

### What size is this battery?

Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. It measures 326×167×241 mm in length × width × height, with the terminals included in the height.

### Deka 8G27 or MK Powered 8G27: which one to choose?

Same case and same technology as the 8G27: an alternative by size, not an official equivalent. Compared with the 8G27 it has the same Ah and cranking power. It costs €425.20 more. If the polarity matches and your equipment had a similar capacity, it works as a replacement; if in doubt, ask us with your model.
