Q 1. What does EFB stand for and why does it matter for my vehicle?

A. EFB stands for Enhanced Flooded Battery. It is a reinforced wet-cell battery designed specifically for vehicles equipped with start-stop systems. Compared to a conventional flooded battery, EFB technology offers superior cycle life and faster charge acceptance, both of which are essential when the engine restarts frequently and the battery must recover charge rapidly during regenerative braking.

Q 2. What are the exact dimensions of the PM249EFB?

A. The battery measures 302mm in length, 175mm in width, and 220mm in height including the terminal. The case type is D31. Please confirm these dimensions fit your battery tray before ordering.

Q 3. What terminal type and polarity does the PM249EFB use?

A. The PM249EFB uses a Type 1 terminal configuration with standard polarity (polarity code 0), meaning the positive terminal is positioned on the right-hand side. The hold-down type is B01. Confirm these details match your vehicle's requirements before fitting.

Q 4. Can the PM249EFB be used as a direct replacement for a conventional lead-acid battery in a start-stop vehicle?

A. Yes. An EFB battery is the minimum recommended replacement for any vehicle originally fitted with an EFB battery. Fitting a conventional flooded battery in its place would result in premature failure. If your vehicle was originally fitted with an AGM battery, an AGM replacement is required instead.

Q 5. What warranty does the PM249EFB carry?

A. The Powermax PM249EFB is supplied with a 3-year warranty against manufacturing defects. Should a warranty claim be required, contact PartsForMachines with proof of purchase and details of the fault.

Q 6. What other batteries are available in the Powermax EFB range?

A. The Powermax EFB range includes the PM017EFB, PM020EFB, PM068EFB, PM096EFB, PM110EFB, and PM115EFB, covering a range of capacities and fitments to suit different vehicles with start-stop systems. Contact PartsForMachines to identify the correct variant for your application.

Q 7. What is the weight of the PM249EFB?

A. The Powermax PM249EFB weighs 19.2kg. This should be considered when planning installation, particularly in confined engine bays or where manual handling is involved.

Q 8. How is the PM249EFB delivered and what is the returns policy?

A. This product is unsuitable for standard carrier shipment due to its classification as a wet battery. Delivery options and availability vary; contact PartsForMachines directly to discuss shipping arrangements. A 30-day returns policy applies.

Q 9. What is the cold cranking amps (CCA) rating of the PM249EFB?

A. The PM249EFB is rated at 800A cold cranking amps measured to the EN standard. This rating reflects the current the battery can deliver for 30 seconds at −18°C whilst maintaining a minimum voltage of 7.5V, and indicates strong cranking performance in cold conditions.

Q 10. Is the Powermax PM249EFB compatible with my start-stop vehicle?

A. The PM249EFB is purpose-built for start-stop applications. Provided the battery matches your vehicle's required specification — 12V, 80Ah, 800A CCA, Type 249EFB, and D31 case — it is suitable. You should always verify compatibility against your vehicle handbook or consult a qualified technician before fitting.
