Parts for your 2020 Suzuki Splash-Batteries

2020 Suzuki Splash batteries — fitment, purpose and service tips

Based on technical references including the Suzuki Splash/Ritz owner’s and service manuals (RB series), and fitment data from major battery catalogues used in AU/NZ workshops (e.g., Bosch Battery Catalogue and Exide Battery Finder), the 2020 Suzuki Splash is an internal-combustion vehicle that uses a 12‑volt automotive battery. There’s no high‑voltage traction pack on standard models, so a conventional 12 V battery is absolutely relevant to this vehicle.

The battery’s job is simple but vital. It cranks the engine, stabilises voltage for the ECU, immobiliser and sensors, and keeps lights, infotainment and accessories happy when the alternator isn’t doing the heavy lifting. Where a Splash is equipped with idle stop/start (available in some markets), an enhanced flooded (EFB) or AGM battery is specified to handle frequent restarts and deeper cycling.

For servicing, workshops typically see Splash batteries in the DIN L1/H4 size class (approx. 207 × 175 × 190 mm) around 44–50 Ah with 390–520 A (EN) cold‑cranking performance, or an equivalent JIS B24 unit depending on market. The positive terminal is usually on the left (conventional L layout). Always match the existing battery’s technology (flooded vs EFB/AGM), case size, and terminal layout, or confirm via VIN‑based parts lookup.

Replacement cadence depends on climate and usage. In Australian and New Zealand conditions, owners generally get 3–5 years from a quality flooded lead‑acid, and 2–4 years for EFB/AGM in heavy start‑stop urban work. Tell‑tales include lazy cranking, dimming at idle, a battery light that lingers, or start/stop disabling itself.

• Test at each service: a quick conductance/CCA test and a charging‑system check saves grief later.
• Keep it charged: 12.6 V at rest is healthy
