Leoch's Maximum Performance Line
The LMX14 is part of Leoch's LMX Maximum Performance line, the top of Leoch's AGM powersport range, above its High Performance LBX series. Here is what Leoch builds into it:
- Radial grid design - a shorter current path inside the battery, which Leoch says gives high cranking power and better charge and discharge performance.
- Heavy-duty copper terminals - Leoch pairs them with the radial grid to get the power out.
- Superior vibration resistance - built for rough road conditions.
- Low self-discharge - Leoch rates the line excellent for seasonal use, when a machine sits between seasons.
- Double-sealed case - sealed twice to reduce leakage and corrosion.
- Factory activated - spill-proof, maintenance-free and ready to install.
Three Numbers on the LMX14 Label
- Marks, then bolts - pair each cable with the LMX14 terminal carrying the same mark as before, then tighten.
- Seat and panels - if any came off to reach the battery, put them back when the bolts are snug.

Frequently Asked Questions
Will the label's numbers change as the battery gets older?
No. They rate the battery as new, and the printed numbers stay put. Age shows in use instead: watch for your F800GS struggling to start, or the battery needing a charge more often.
Which way are length, width and height listed in the spec table?
In that order, L x W x H, inches first, then millimeters. Length runs along the long side with a terminal toward each end, width across the short side, and height from the bottom up.
Can I test the battery's capacity at home?
Not the 13AH rating itself, which takes a controlled discharge on test equipment. A voltmeter across the terminals shows its state of charge after the battery has rested off the charger, and a service shop can load-test it.
Read us the numbers off the label you're looking at, and a specialist will explain each one for your F800GS.
