A motorbike battery that delivers dependable starting power and flexible installation for performance bikes, the Yuasa YTZ10S Motorbike Battery suits riders who need reliable starts. Reliable starts, maintenance-free use and resistance to vibration and corrosion remove much of the pre-ride worry. Is the sealed AGM construction and brass-terminal build the right upgrade for riders who demand longevity?
⚡ At a Glance
- • Starting Power: 190 CCA, 12V VRLA AGM construction with 9.1 Ah (20‑HR) capacity
- • Best for: High-performance sport bikes and motorcycles equipped with Start-Stop systems
- • Not ideal for: Owners who prefer serviceable flooded batteries that require topping up
Sealed 12V VRLA AGM construction supplies 190 CCA and 9.1 Ah capacity for dependable starting. Brass terminals and resistance to vibration and corrosion aim to extend service life under demanding use.
Flexible fit and leakproof mounting – with VRLA AGM sealed construction
Valve regulated lead acid (VRLA) AGM design seals electrolyte within the battery, allowing secure installation without a risk of leakage. Product notes confirm mountings at extreme angles are supported, so orientation does not compromise the sealed system.
Mount at odd angles or in tight trays commonly found on sport bikes without fear of spills. Installation options become more forgiving for custom and compact battery bays.
Confident starts after storage – thanks to 190 CCA and 9.1 Ah capacity
Cold cranking amps measure surge current available to the starter and the 9.1 Ah (20‑HR) rating indicates available reserve capacity. Those specifications combine to deliver the high current demands of starter motors and reserve energy for intermittent use.
Reliable starting even after periods of non-use and consistent cranking for Start-Stop systems reduces failed-start anxiety. Several user reports confirm dependable starts and good charge retention after weeks unused.
Durable electrical connection – with brass terminals and anti-corrosion construction
Brass terminal fittings provide superior conductivity compared with some alloys, improving current transfer at the connection point. Construction designed to resist vibration and corrosion protects electrical contacts in harsh riding environments.
Reduced voltage drop at the terminals and fewer connection faults lead to steadier cranking performance. Robust connections and anti-corrosion measures help avoid roadside failures and premature replacement.
