Battery Kit – 14.7Ah Sealed AGM (Sportster S / Nightster)

Description

This genuine Harley-Davidson battery kit is a 12-volt, 14.7 amp-hour sealed AGM (absorbed glass mat) battery built to Harley-Davidson’s original equipment specification for Revolution Max Sportster models. Compact and light, it still delivers the cranking current these high-compression engines demand.

Sealed, maintenance-free construction means no topping up and no spills, with strong vibration resistance, low self-discharge and full compatibility with H-D battery tenders.

Fitment: Listed for 2026 RH1250S Sportster S, RH975 Nightster and RH975S Nightster Special. May also be the current replacement for earlier RH-model batteries (such as 66000208) – check fitment with our parts team.
