What kind of battery does the 2025 Fiat Grande Panda have? 🔋 A complete guide to gasoline, hybrid, and electric vehicles.
Updated October 2025 — by Gianni Tritella. The 2025 Fiat Grande Panda uses three different battery types depending on the engine (petrol, mild hybrid, electric). In this article, we analyze in detail which battery each version uses , with real data collected in the workshop and confirmation from the first models on the road. You'll find voltages, capacities, technologies, codes, and maintenance tips to avoid replacement errors or misdiagnosis.
EXIDE EB620 – CAR BATTERY 62Ah 540A/EN
12V 62Ah 540A/EN car battery with advanced lead-calcium technology. Dimensions 242×175×190 mm , ideal for medium-sized vehicles. Guarantees reliable starting and long life.

One of the most frequently asked questions following the release of the new Fiat Grande Panda concerns the battery: “ What type does it have? ” and “ Is it the same for all versions? ”. The answer is no: the new Panda, built on the STLA Small platform shared with the Jeep Avenger and Fiat 600, adopts different solutions to power the 12 V, 48 V, and high voltage (HV) systems depending on the type of engine.
🔧 Petrol version (1.2 EB2)
The pure petrol versions are equipped with a traditional 12 volt EFB (Enhanced Flooded Battery) battery, necessary to support the Start&Stop and modern electronic systems.
| Parameter | Specifications |
|---|---|
| Installed model | Exide EB620 (or equivalent Varta E44 / Fiamm Titanium Pro 62Ah) |
| Type | EFB – reinforced lead-acid |
| Rated voltage | 12 V |
| Capacity | 62 Ah |
| Cue (CCA) | 540 A (EN) |
| Polarity | Positive on the right (DX) |
It is the same battery also used on the Fiat 600 1.2 and Jeep Avenger 1.2, confirming the Stellantis standardization for EB2 engines. After replacement, it is mandatory to perform an IBS (Intelligent Battery Sensor) reset via diagnostics to avoid DTC U3003 or false energy warnings.
⚡ Mild Hybrid Version (MHEV 48 V)
The Grande Panda MHEV uses two separate batteries:
- a 12 V auxiliary battery (same model Exide EB620);
- a 48V lithium battery dedicated to the hybrid system.
| Component | Specifications |
|---|---|
| 12V battery | Exide EB620 – EFB 62 Ah 540 A EN |
| 48V battery | Lithium-Ion – 48 V, capacity ~0.9 kWh |
| Converter | DC-DC 48 → 12 V for charging and service network management |
The 12V EFB works in synergy with the 48V system and the DC-DC converter, keeping the infotainment and body computer active even with the engine off. The 48V battery, on the other hand, is dedicated to the electric motor integrated into the 6-speed DCT transmission and recharges during deceleration.
🔋 Electric Version (BEV)
The Big Panda Electric (BEV) uses two batteries:
- a lithium iron phosphate (LFP) HV (high voltage) battery ;
- a 12 V AGM auxiliary battery to power low voltage services (lights, control units, climate control, etc.).
| Parameter | Specifications |
|---|---|
| HV (traction) battery | Lithium LFP – 44 kWh gross (~43.8 kWh useful) |
| Rated voltage | 400 V architecture |
| 12V auxiliary battery | AGM – 12 V 35–40 Ah (charged by DC-DC HV → 12 V) |
The main LFP battery provides traction power, while the 12V manages the services and on-board electronics. Both work synergistically through a highly efficient DC-DC converter, which maintains stable voltage during charging or standby.
📌 Conclusions
The 2025 Fiat Grande Panda uses three distinct battery architectures: a 12V EFB for gasoline and mild hybrids, a 48V lithium module for the hybrid version, and a 400V LFP for the electric version. The use of the Exide EB620 as standard on gasoline and MHEV models confirms Stellantis' decision to standardize the 12V network across the entire range, simplifying maintenance and spare parts. Knowing the correct battery type—and how to manage it—is essential to avoid electronic failures, false alarms, and premature replacements.
