The Motobatt MB7U is a sealed 12V AGM powersports battery built around Motobatt's patented QuadFlex terminal layout — two positive and two negative posts — so a single part number covers a wide spread of motorcycle, scooter, ATV and small-engine fitments, and leaves spare posts free for accessory wiring. It is a direct replacement in applications calling for a YT7B-BS style battery.
Each plate is wrapped in absorbed glass mat, which holds the electrolyte and cushions the plates against vibration — a common cause of shorted plates and broken welds in traditional flooded batteries. The thicker plates and higher amp-hour rating also let the MB7U handle repeated deep cycling and recover under alternator or maintenance charge.
It arrives factory activated: pre-conditioned, fully charged and ready to bolt in with no acid filling. Because it holds no free liquid acid, it can be shipped by courier and mounted in any orientation.
- Patented QuadFlex four-terminal design — two positive, two negative posts for multi-fit versatility
- Absorbed Glass Mat (AGM) construction for vibration resistance and longer service life
- Factory activated — pre-charged and ready to install straight out of the box
- Maintenance free: no acid handling, no fluid top-ups, no terminal gassing
- Fully sealed and non-spill — can be mounted and transported in any position
- 12V, 7Ah at C(10) and 7.4Ah at C(20)
- 100A cold cranking amps (CCA), 158A MCA and 324A pulse hot cranking amps
- Thick, heavy plates suited to repeated deep discharge and recharge cycling
- Lower self-discharge rate than conventional flooded batteries
- Spare terminals allow easy connection of accessories
- Contains no liquid acid, so it can be sent by standard courier

- No activation or initial charging is required — the MB7U ships factory activated and fully charged, so it can be installed straight from the box.
- Check the battery box dimensions (151 x 65 x 94 mm) and terminal orientation against your bike before fitting; this model is supplied without height spacers.
- Fit the supplied M5 terminals with the M5 x 7 screws and the included 3 x 3 Allen wrench. Tighten firmly by hand only — over-torquing can strip or damage the posts.
- Connect the positive lead first and disconnect it last. Fit the supplied terminal caps over the unused posts to prevent accidental shorting.
- The spare positive and negative posts can be used for accessory leads; keep total accessory draw within your charging system's capacity.
- Secure the battery in its tray with the factory strap or holder so it cannot move — AGM plates resist vibration well, but a loose battery can chafe wiring or crack the case.
- Never open the case, add water or top up electrolyte. The battery is sealed and maintenance free.
- Recharge with an AGM-compatible charger or a smart maintenance charger. Do not use a high-current, unregulated or manual charger, as excessive voltage will damage AGM plates.
- If the bike is stored or ridden infrequently, keep the battery on a maintenance charger or recharge it periodically — AGM self-discharge is low but not zero, and letting it sit flat shortens its life.
- Wipe the case and terminals with a clean, dry cloth. Avoid solvents and keep the posts free of grime and moisture.
- Store off the vehicle in a cool, dry place and recharge before returning it to service after a long lay-up.
- Do not dispose of the battery in general waste — return it to a battery recycler or collection point.
