Which Isuzu models and years will this cover fit?

This cover fits multiple Isuzu medium-duty truck families across several years and engine sizes. Compatibility includes NPR, NPR-HD, NQR, NRR, FRR and related chassis where the OEM part number 1536120291 applies.

• Isuzu NPR/NPR-HD/NQR/NRR 3.0L and 5.2L models from 2008–2015

How do I confirm this is the right cover for my truck?

Because Isuzu used different battery arrangements across years and trims, visual verification is the safest way to ensure a correct match. Compare the pictures provided for the part with your current battery enclosure and the OEM part number if available.

• Check the OEM part number on your existing cover or service manual
• Compare mounting points and overall shape to photos before ordering
• Verify engine size and model year against the compatibility list above

What material and durability can I expect?

The cover is molded from robust black plastic to resist impact, road grime and moisture. It’s intended as a protective housing rather than a structural component, so it restores the original weather protection and appearance of the battery area.

• Injection-molded black plastic construction
• Designed to shield batteries from debris and splashes
• Lightweight yet durable for routine commercial use

How easy is installation and what do I need?

Installation is typically straightforward and mirrors the removal process of the original cover. Basic hand tools are usually all that’s required to remove fasteners and secure the replacement, but confirm mounting hardware compatibility first.

• Remove old cover and any retained fasteners before fitting the new unit
• Use corresponding bolts or clips—reuse OEM hardware if in good condition
• No electrical or battery modification required; installs as a direct replacement when matched properly

Who is this for: This Boursin battery box cover is aimed at fleet managers, independent mechanics and truck owners who need a reliable, OEM-style replacement for Isuzu medium-duty trucks listed above. It’s best for those who can verify fitment by part number or by comparing photos of their current battery housing, and who want a simple, durable solution to protect their vehicle’s battery from the elements.
