MBTX20U -- 20ah Battery Upgrade MBTX20U

Motobatt MBTX20U AGM JetSki Battery

Most JetSkis come with a budget battery designed just to get you through the warranty period. They’re light, cheap, and often underpowered — which is why so many riders end up with flat starts, unreliable cranking, and early failures.

The Motobatt MBTX20U is a serious upgrade. Engineered with Quadflex Technology, it packs up to 30% more power and capacity than standard batteries of the same size. That extra punch makes cold starts easier, keeps electronics running stronger, and lasts longer on the water. Its sealed AGM design is totally spill-proof, vibration-resistant, and maintenance-free – built to handle the pounding, spray, and shock that JetSkis throw at it.

Factory charged to 12.5V+, it’s ready to drop in and ride straight away. No acid, no top-ups, no stress. Just reliable cranking power every time you hit the start button.

Why Upgrade to Motobatt?

• Factory Batteries = Weak – OEM JetSki batteries are often low-spec and fail quickly under real use.

• More Power – Quadflex internal plate design gives higher CCA (cold cranking amps) for fast, reliable starts.

• Marine Tough – built to resist pounding waves, salt spray, and vibration.

• Maintenance-Free – sealed AGM means no spills, no acid, no topping up.

• Ready to Ride – arrives fully factory activated and charged.

• Secure Fit – solid-mounted, threaded terminals for strong connections.

• Warranty – backed by a 12-month full replacement guarantee.
