YTX20H-BS Battery Cross Reference
A YTX20H-BS is a sealed agm (maintenance-free). It fits 123 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.

A YTX20H-BS fits 123 powersports models in our data, including the Arctic-Cat 450, TRV, CORE, Arctic-Cat 450, TRV, CORE, Arctic-Cat 4x4 Automatic. It is a sealed agm (maintenance-free).
Is there a lithium equivalent to the YTX20H-BS?
Yes. LiFePO4 lithium drop-ins are made in the YTX20H-BS 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 YTX20H-BS code mean?
The -BS suffix means it ships dry with an acid pack you add once - after that it is a sealed, maintenance-free AGM battery.
