MK Battery M17-12 SLD M in everyday use
Holiday trips with a folding scooter mean charging in unfamiliar places. Use the charger supplied with the chair or one set for the AGM chemistry. Batteries left flat in storage often never recover.
The AGM technology explained
Glass-mat batteries are sealed, with small valves that only open if pressure builds up. Motorcycles benefit from glass-mat batteries because they tolerate lean angles and vibration. Over winter, a smart unit set to its AGM programme keeps a glass-mat battery healthy with no effort.
Five checks for a perfect fit
- ✓ Tape measure time: 181.1 × 75.9 × 166.9 mm is the footprint and height of this case. Leave a little clearance for the clamp and the cable lugs.
- ✓ Capacity 18Ah: equal to or a little above your old label is ideal.
- ✓ As a AGM battery it needs matching charge settings in the alternator, charger or solar regulator.
Answers before you buy
Does a battery lose charge on the shelf?
It is a good idea. All batteries lose some charge on the shelf, so a top-up before fitting helps.
Dimensions and weight of this model?
Length, width and height are 181.1 × 75.9 × 166.9 mm, and the weight is 5.85 kg. Compare with the space available, including clearance above the posts.
What are the voltage and capacity of this model?
Yes, if they are identical. Two 12V units of 18Ah in series give double the voltage; in parallel they give double the capacity at 12V.
Does my charger suit the technology of this battery?
It is built with AGM technology. Pick charging equipment with a matching mode and avoid storing it discharged.
