What the MK Powered 8GU1H is for
The MK Powered 8GU1H 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 10.66 kg and LT terminals.
The MK Powered 8GU1H: Mk GEL range and GEL technology
Within the MK Powered catalogue, the Mk GEL series groups the references designed for this use. The 8GU1H is the 31.6 Ah model of that family, with the same performance as its siblings in other sizes.
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.
Size, terminals and hold-down of the MK Powered 8GU1H
It has external dimensions of 213 × 131 × 183 mm and weighs 10.66 kg. It uses LT terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
MK Powered: the maker behind the 8GU1H
MK batteries are the standard in the electric mobility sector: sealed, approved for air transport and with the consistency that wheelchair manufacturers demand as original equipment. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
Care and maintenance
GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity.
Official warranty
The MK Powered 8GU1H 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.

How to change the battery
Guide to replace a cyclic battery (12V 4-30Ah) for UPS, mobility scooter, alarm or backup device. Estimated time 10-15 minutes. Important: discharge residual voltage before handling.
Step 1. Power off and unplug the device
Unplug the device (UPS, scooter, alarm) and leave it off for at least 30 seconds to discharge residual capacitor voltage. Work on an insulating surface.
Step 2. Locate the battery compartment
Usually under the seat (mobility scooter/wheelchair), in the rear module of the UPS, or behind a side panel with screws. Check the device manual for unusual models.
Step 3. Disconnect the negative (−) first
With insulated gloves, remove the negative (−) cable first. Some UPS have protection fuses — note their position before removing.
Step 4. Disconnect the positive (+) terminal
Repeat with the positive cable (red, marked +). Important: never let a terminal touch metal of the car while the other is still connected.
Step 5. Remove the old battery
Typical weight 1-15 kg depending on capacity. Many cyclic batteries are AGM/GEL — keep them upright. Do NOT invert the battery: even sealed, residue may exist.
Step 6. Fit the new battery
Same orientation and type (AGM, GEL or flooded). Polarity must match the device, not a chassis (this is not a car). Make sure terminals do not touch metal parts of the compartment.
Step 7. Connect the positive (+) first
On cyclic devices the order is reversed compared to cars: positive (+) first, negative (−) afterwards. Tighten without forcing — the plastic terminal housing of cyclic batteries damages easily.
Step 8. Initial charge before first use
Cyclic batteries ship at 60-80%. Before first use, connect the device charger for 8-12 hours (or use an AGM/GEL smart charger if available). This avoids short cycles and extends lifespan.
Frequently asked questions
Is the 8GU1H model a gel battery? Where is it used?
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 do I fit the 8GU1H 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 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.
How many years does this battery last?
Expected lifespan of the MK Powered 8GU1H 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 dimensions of the MK Powered 8GU1H battery?
Dimensions (length × width × height) are 214×132×183 mm — also written as 214x132x183 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 8GU1H 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.
