Frequently Asked Questions

Will this battery fit and start my motorcycle, ATV, or newer lawnmower?

Yes — the S4 is the most compact starter in the Ionic line, built for motorcycles, UTVs, ATVs, and newer lawnmowers, with 500 peak cranking amps. It covers an unusually wide range of sizes through six Case options and included spacers — from a BTX14-BS/YTZ10S up to YTX16/YB16 sizes. Use the Battery Finder tool or the Fitment Cross Reference to pick the right Case and spacer count for your exact model.

Which Case option (S4 through S4V) do I need?

The Case option sets the physical size and number of fitment spacers for a snug, direct fit. As a guide: base S4 fits BTX14-BS/YTZ10S; S4I fits YTX9-BS/YTZ12S/YTZ14S; S4III fits YTX12-BS/YB12 sizes; S4IV fits YTX14-BS/YTX14L-BS; and S4V fits the larger YTX16/YTX20CH/YB16 sizes. The Battery Finder tool will tell you the exact Case and spacer count for your vehicle.

How does the Emergency Start feature work, and can I leave my bike parked?

Yes — this is a favorite use. The battery automatically reserves 25% of its capacity, so if you leave a motorcycle parked for weeks and the battery self-protects by shutting off, you can long-press the button on the battery (or use the Ionic app) to tap the reserve and start the engine. Owners use the app’s on/off control to prevent parasitic drain without a trickle charger.

Can I mount this battery on its side?

Yes — it’s a sealed lithium battery with no liquid electrolyte, so it installs in any orientation, upright or on its side. It uses M6 threaded terminals with a quad-post layout for flexible cable routing; an M6-to-top-post adapter is available if your cables need standard posts. Because the battery is smaller than many OE cases, the included spacers fill the gap for a secure fit.

Will my motorcycle or UTV keep it charged, and what charger should I use for storage?

Yes — your vehicle’s charging system tops it off while running. For storage or seasonal use, the Ionic 12V 2A trickle charger is a good match for this small 4Ah battery and is safe to leave connected; it switches to float mode once full. Use only LiFePO4-compatible chargers that top out at 14.6V, and avoid lead-acid chargers with a “Desulfate” mode.
