This guide focuses on Scania heavy trucks and buses (P/G/R/S series; older 4‑series; K/N/C‑series buses). Most Scania road vehicles run a 24V system using two 12V batteries in series. Always match capacity, construction (EFB/AGM), physical size, and terminal layout to your VIN build sheet or the tray dimensions. When you’re ready to compare, jump directly to curated searches: Group 31 AGM (North America), DIN 642 ~200Ah (EU HGV), DIN 629 ~180Ah, H8/L5 AGM (aux/coach bays), and 12V 100Ah AGM (auxiliary).

Top Battery Types for Scanias (What to Choose & Why)
| Type | Best For | Typical Specs | Approx. Price (each) | Shop |
|---|---|---|---|---|
| Flooded (Lead‑Acid) – Commercial | Older trucks; low accessory loads; mild climates | 140–225Ah, 800–1200 CCA | $140–$220 | Group 31 | DIN 629 |
| EFB (Enhanced Flooded) | Frequent stop/start; delivery; moderate hotel loads | 160–200Ah, higher cycle life than flooded | $170–$280 | Commercial EFB |
| AGM (Absorbent Glass Mat) – Starter | Long‑haul with hotel loads; high vibration; cold climates | 180–225Ah, 900–1400 CCA; fast charge acceptance | $220–$370 | Group 31 AGM | DIN 642 AGM |
| AGM Deep‑Cycle (Auxiliary) | Bus/coach aux banks, inverters, tail‑lift packs | 70–200Ah per 12V module; low internal resistance | $160–$350 | Deep‑cycle AGM |
Scania Model‑Specific Buying Tips
- S‑series / R‑series tractors: Usually twin 12V commercial batteries in series (24V). Favor AGM 200–225Ah for hotel loads and cab comfort systems. Budget builds can use EFB 180–200Ah. ~$200–$360 each.
- G‑series / P‑series rigids: Mixed duty with PTO and body equipment; EFB is a cost‑effective upgrade from flooded. ~$170–$280 each.
- 4‑series (older): Check tray length/height; many use DIN 629/640 in steel side trays. Keep to OE Ah and height to fit clamps. ~$160–$240 each.
- K‑/N‑series bus/coach: Separate starter pair plus auxiliary bank for HVAC and infotainment. Consider AGM starter and deep‑cycle AGM for aux.
Starters: DIN 642 AGM; Aux: AGM deep‑cycle 12V. - Cold‑region fleets: Match or exceed OE CCA by +100 where possible; add insulated covers and ensure alternator output curve matches AGM/EFB chemistry.
- Hot‑region fleets: Heat kills batteries; prioritize RC/Ah and ventilated boxes. EFB/AGM tolerate heat and vibration better than standard flooded.
Scania Battery Fitment Cheat Sheet (Most‑Common Sizes)
| Platform | System | Common Size Codes | Typical Capacity | Notes | Shop |
|---|---|---|---|---|---|
| R/S‑series tractors (Euro 6) | 24V (2×12V) | DIN 640/642 (EU) | BCI Group 31 (NA) | 190–225Ah, 1000–1400 CCA | AGM preferred for hotel loads & vibration | 642 ~200Ah | Grp 31 AGM |
| P/G‑series rigids & tippers | 24V (2×12V) | DIN 629/640 (EU) | Group 31 (NA) | 170–200Ah, 900–1200 CCA | EFB is a solid durability upgrade | 629 ~180Ah |
| Older 4‑series | 24V (2×12V) | DIN 627/629 | 140–180Ah | Check tray height/hold‑down lip | 627 ~150Ah |
| K/N‑series buses | 24V start + 12V/24V aux | DIN 640/642 (start) + H8/L5 or 100Ah AGM (aux) | 200–225Ah start; 70–150Ah aux | Isolate aux bank; use DC‑DC charging if mixed chemistries | H8/L5 AGM |
Spec Targets: CCA, RC/Ah, and Warranty
CCA: Cold Cranking Amps Ah/RC: Capacity/Reserve Tech: Flooded / EFB / AGM
- CCA: Meet or exceed OE. Cold fleets aim for +100 CCA vs. minimum.
- Ah/RC: Higher Ah supports sleepers, parking A/C, and PTO controls with engine off.
- Technology: If OE was EFB/AGM, don’t downgrade to standard flooded.
- Warranty: Target 24–36 months commercial free‑replacement (region‑dependent).
- Charge Strategy: Verify alternator profile supports AGM/EFB; slow chargers should have an AGM/EFB mode.
- Orientation: Match terminal layout; many Scania trays use side clamp lips—height matters.

- Where to buy:
- Dealer/fleet parts counter – VIN‑matched, install service, core handling.
- Commercial battery specialists – Load testing, same‑day swap, recycling.
- Online – Price and spec comparisons; verify date codes and freight terms.
- Pro tip: For 24V trucks, replace batteries as a matched pair to avoid imbalance.
How to Check Freshness & Authenticity
- Read the date code on the case or label; target stock ≤ 6 months old.
- Visual check: straight case walls, intact vents, clean posts, no acid residue.
- Open‑circuit voltage (rested): ≥12.6V (AGM often ~12.8V) before install.
- Match labels to invoice (Ah/CCA, tech type). Beware scraped/relabeled cores.
- Buy from reputable sellers; keep receipts and serials for warranty.
Car Battery Warranty Tips
- Understand commercial vs. consumer terms—fleet duty may shorten coverage.
- Keep charge logs if you idle‑free overnight (hotel loads); some policies require proof of proper charging.
- Document alternator output and parasitic draw tests at install time.
- Always return cores promptly to avoid fees.

Scania Car Battery Installation Guide (DIY or Shop)
- Park safely, apply parking brake, chock wheels, and switch off all loads.
- Locate the battery box (frame‑mounted tray or side locker). Open/clean area.
- Take photos of cabling and series links (24V = two 12V in series). Label cables.
- Wear PPE. Disconnect negative on both batteries, then positives. Remove the interlink last.
- Release hold‑downs and lift out old units. Neutralize any acid residue; clean clamps and tray.
- Compare new batteries: tech type, Ah/CCA, height, terminal layout. Install as a matched pair.
- Seat batteries; torque hold‑downs to spec (no case bulge). Install series interlink.
- Connect positives first, then negatives. Ensure tight, corrosion‑free connections.
- Program/start vehicle. Verify charging voltage (≈28.0–28.8V running; AGM typically toward upper range).
- Load‑test after a short drive; clear dashboard warnings if present.
Scania Car Battery Maintenance & Longevity
- Use a quality 24V‑compatible maintainer or two synchronized 12V smart chargers (AGM/EFB mode).
- Minimize deep discharges from hotel loads; consider separate aux bank with low‑voltage cut‑off.
- Keep terminals tight and protected with dielectric grease (not on contact surfaces).
- Inspect tray vibration mounts; replace perished rubbers to protect plates.
- Test alternator ripple and voltage regularly; high ripple shortens AGM life.
- For seasonal downtime, store fully charged and top off every 4–6 weeks.
Signs You Need a New Battery
- Slow crank, especially after overnight hotel loads.
- Repeated low‑voltage warnings, dim dome lights, or ECU undervoltage codes.
- Visible case swelling, leaks, or rotten‑egg smell (overcharge).
- Fails a professional load test or shows high internal resistance.

Scania Car Battery FAQs
What battery type does a Scania typically use?
Many Scania vehicles use heavy-duty 12V batteries in a 24V system (two 12V in series). Check your VIN/manual for the exact spec and technology (Flooded, EFB, or AGM).
Can I replace Flooded with AGM on a Scania?
Yes—AGM is generally an upgrade for vibration resistance and deep-cycle durability. Do not downgrade from AGM/EFB to standard Flooded on trucks with start-stop or high electrical demand.
Do Scania trucks have start-stop or energy management that require battery coding?
Some models use intelligent charging/BMS. If you change battery type or capacity, use a capable scan tool to register the new battery so charging profiles are correct.
What size (capacity) should I choose?
Match or exceed OE spec for Ah and CCA. Many Scania applications use high-capacity batteries (e.g., 180–225Ah combined at 24V) depending on model, climate, and auxiliary loads.
How long should a Scania car battery last?
Typically 3–5 years in mixed duty. Harsh climates, frequent short trips, high parasitic loads, and heavy vibration can shorten life to 2–4 years; long highway runs and maintenance charging can extend it.
How much is a Scania car battery?
Expect roughly $150–$350 per 12V battery for quality Flooded/EFB and $250–$500 for AGM, with most trucks needing two batteries (totaling $300–$1,000+ depending on brand/spec).
How do I know if my Scania batteries are failing?
Hard starts, dim lights, slow cranking after rest periods, frequent DPF/AdBlue or electrical warnings, and resting voltage repeatedly under ~12.4V (per battery) are common signs.
Should I replace both batteries at once?
Yes—on 24V systems replace batteries as a matched pair (same brand, age, capacity) to avoid imbalance and premature failure.
What maintenance helps Scania battery life?
Keep terminals clean/tight, secure clamps to reduce vibration, use an appropriate smart charger during long downtime, and fix parasitic draws. Verify alternator output and chassis grounds.
Can I mix different battery brands or ages?
Avoid mixing. Mismatched internal resistance and capacity stresses both batteries and can shorten service life.
