YTZ14S Battery Cross Reference
A YTZ14S is a sealed agm (maintenance-free). It fits 78 powersports models in our data, and a lithium drop-in is made in the same case size.
AGM is the safe like-for-like: cheapest, tolerant of standard chargers and trickle tenders, and heavier. Lithium (LiFePO4) drop-ins in the same case size cut weight by roughly 60-70%, hold voltage better, and self-discharge far slower - but they cost more and need a lithium-aware charger, not an old lead-acid trickle charger.

Frequently asked
What vehicles use a YTZ14S battery?
A YTZ14S fits 78 powersports models in our data, including the BMW C600, BMW F700GS Auxiliary Battery, BMW F700GS Auxiliary Battery Only. It is a sealed agm (maintenance-free).
Is there a lithium equivalent to the YTZ14S?
Yes. LiFePO4 lithium drop-ins are made in the YTZ14S case size, so they fit the same tray and terminals. They weigh far less and last longer, but need a lithium-aware charger.
What does the YTZ14S code mean?
YTZ14S is a standard powersports battery case-size code that fixes the physical fit, terminal layout, and capacity.
