MK Powered MU-1 SLD M-2 12V 35Ah is a deep-cycle battery for wheelchairs and mobility scooters, optimised to be discharged and recharged daily down to 80 % DOD without losing range.
Designed for power wheelchairs, mobility scooters and light electric vehicles, the MK Powered MU-1 SLD M-2 from the Mk AGM range offers 35 Ah of deep-cycle capacity with AGM technology. It replaces the original battery without adaptation in power wheelchairs and mobility scooters with a 197 × 131 × 180 mm format: same 35 Ah capacity.
The MK Powered MU-1 SLD M-2 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 10.48 kg and F4 terminals.
The MK Powered MU-1 SLD M-2 is made in the 197 × 131 × 180 mm format and weighs 10.48 kg. It uses F4 terminals, the system that anchors and connects it in the vehicle. 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.
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. All the MK Powered batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
Within the MK Powered catalogue, the Mk AGM series groups the references designed for this use. The MU-1 SLD M-2 is the 35 Ah model of that family, with the same performance as its siblings in other sizes.
In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.
Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.
The MK Powered MU-1 SLD M-2 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.
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.

Yes. The MU-1 SLD M-2 from MK Powered uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for devices with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.
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.
Expected lifespan of the MK Powered MU-1 SLD M-2 is 5 to 8 years in mild-climate device use with 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.
Dimensions (length × width × height) are 197×131×180 mm — also written as 197x131x180 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.
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.
