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. ### Dimensions, polarity and mounting 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. ### Why choose MK Powered batteries 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. ### The MK Powered MU-1 SLD M-2: Mk AGM range and AGM technology 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. ### How to make it last longer 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. ### Warranty and coverage 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. ### When you get it and how to return it Orders placed **before 6:00 pm** with the battery in stock ship the same day.
