Q 1. What vehicle types is the Deta DB621 suitable for?

A. The DB621 is designed for standard, non-start-stop passenger cars and light vehicles that require a Type 078 equivalent battery. It is not suitable for vehicles equipped with start-stop, micro-hybrid, or regenerative braking systems.

Q 2. What is the Cold Cranking Amps (CCA) rating of the DB621?

A. The Deta DB621 has a Cold Cranking Amps (EN) rating of 540A, which represents its ability to deliver sustained starting current at low temperatures in accordance with the EN standard.

Q 3. What are the physical dimensions of the DB621?

A. The DB621 measures 242mm in length, 175mm in width, and 190mm in height including terminals. It is housed in a Type L02 case and weighs 14.2kg.

Q 4. What terminal polarity does the DB621 use?

A. The DB621 uses terminal polarity 1, meaning the positive terminal is positioned on the right-hand side when the battery is viewed from the front with terminals facing upward. Confirm polarity compatibility with your vehicle before fitting.

Q 5. Which industry cross-reference does the DB621 correspond to?

A. The DB621 is a direct cross-reference for the Type 078 battery group, a widely used standard fitment across many European passenger car models. Verify against your vehicle handbook or existing battery label before ordering.

Q 6. What hold-down type does the DB621 require?

A. The DB621 requires a B13 hold-down bracket. Ensure your vehicle's battery tray and retaining hardware are compatible with this hold-down type prior to installation.

Q 7. Can the DB621 be used in a start-stop vehicle?

A. No. The DB621 is a standard flooded lead-acid battery and is explicitly not suitable for start-stop, EFB, or AGM-dependent vehicle applications. Use in such vehicles may result in premature failure and will affect warranty validity.

Q 8. What technology does the Deta Excell range use?

A. The Deta Excell range features Deta's 3DX grid technology, which improves the structural and electrical properties of the battery's internal plate grids. This contributes to better electrical performance and a longer operational lifespan compared with conventional grid constructions.

Q 9. What warranty is provided with the Deta DB621?

A. The DB621 is covered by a 4-year manufacturer's warranty. This warranty applies to defects in materials and workmanship under normal operating conditions. Warranty claims arising from misapplication, including use in start-stop vehicles, will not be upheld.

Q 10. How is the Deta DB621 delivered and what is the returns policy?

A. The DB621 is dispatched via standard parcel delivery and is typically delivered within 1–3 working days to UK mainland addresses. A 30-day returns policy applies. Contact PartsForMachines customer services for returns authorisation and further details.
