FAQ

Before you swap it

Not sure it matches your old battery? Our team checks part numbers every day.

Will this fit my Honda NSS250 Reflex (2001-2009)?

The YTZ12S is listed for Honda NSS250 Reflex (2001-2009). Match the voltage (12V), capacity (11Ah), size (5.91 × 3.44 × 4.38 in) and terminal to your old battery, or use the fit check at the top of this page.

How often should it be replaced?

Sealed lead-acid batteries in standby equipment such as alarm panels, fire panels and UPS units are typically replaced every 3–5 years, or sooner if the system reports a low battery or fails its load test. The date code on the label shows when the battery was made.

Can I use a battery with more amp-hours?

Usually, if the voltage, case size and terminals match: more amp-hours means longer runtime. Check that it fits the compartment and that your charger can recharge it in the time your system requires.

Shipping is free on this battery. Orders placed by 3 PM ET ship the same business day from our US warehouse. See shipping details.
