The **MK Powered 8G27** with GEL technology delivers **72 Ah** at **12 V** with the cycle life that power wheelchairs, mobility scooters and light electric vehicles demand. Measuring 326 × 167 × 241 mm, it is the direct replacement for power wheelchairs and mobility scooters fitted from the factory with a 72 Ah battery of this format.
- GEL: excellent resistance to deep discharge and long cycle life.
- Sealed AGM/GEL: safe indoors and in transport.
- No maintenance, no water top-ups.
- Approved for air and sea transport (VRLA).

### What the MK Powered 8G27 is for

The MK Powered 8G27 is the usual replacement in power wheelchairs, mobility scooters and light electric vehicles. Recharge after each use and avoid leaving it discharged for days. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 28.12 kg and DT terminals.

### Technology inside the MK Powered 8G27

MK Powered builds the 8G27 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.

### Dimensions, polarity and mounting

It has external dimensions of 326 × 167 × 241 mm and weighs 28.12 kg. It uses DT terminals, the system that anchors and connects it in the vehicle. 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.

### What MK Powered does differently

MK Battery (MK Powered) is the US specialist in AGM and GEL batteries for mobility: power wheelchairs, scooters and medical equipment rely on its batteries for safety and cycle life. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

### Usage and maintenance tips

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.

### Manufacturer's warranty

The MK Powered 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.

### Delivery times and returns

Order **before [[ks:cutoff]]** 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 **[[ks:return_days]] 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, this model is a GEL battery: sealed lead-acid where the electrolyte is in gel form. It tolerates deep discharges very well and is ideal for cyclic use (solar, motorhomes, electric wheelchairs, motorcycles). Requires a GEL-specific smart charger — max charge voltage ~14.1 V (vs 14.4-14.7 V for AGM). Lifespan 6-10 years.

### How is the MK Powered 8G27 battery installed in the vehicle?

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 this page. 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 8G27 model?

Expected lifespan of the MK Powered 8G27 is 6 to 10 years in cyclic use (marine, caravan, solar) with controlled discharges. 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 8G27 model?

Dimensions (length × width × height) are 326×167×241 mm — also written as 326x167x241 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 batteries are equivalent to the MK Powered 8G27?

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.
