Product Number: 100EFB
Variations
Modern start-stop vehicles place exceptional demands on the battery, requiring a unit capable of withstanding repeated deep discharge and rapid recharge cycles that would quickly degrade a conventional flooded battery. The Numax 100EFB is an Enhanced Flooded Battery engineered specifically to meet these requirements, delivering reliable engine restart performance alongside the capacity to support the vehicle's auxiliary electrical systems during extended idle periods.
Built to Numax's high manufacturing specification, the EFB technology employs a polyester scrim reinforcement within the positive plate structure. This significantly improves charge acceptance and cycle durability compared to standard flooded designs, making the 100EFB well suited to vehicles equipped with basic start-stop management systems.
The 100EFB delivers 12V with a 65Ah capacity (C20) and 650A cold cranking amps (EN), providing confident starting across a wide range of operating temperatures. The battery measures 277mm × 174mm – 175mm (L × W × H) and weighs 16.9kg. It is supplied in a LB3 case format with Type 1 terminals, negative terminal to the left (polarity 0), and B13 hold-down configuration. The Numax part number 100EFB serves as its own cross-reference.
This product is available in related EFB variants: 005LEFB (PID000138365) and 027EFB (PID000138368), which cover alternative terminal layouts and BCI group fitments within the Numax EFB range.
The 100EFB is backed by a 3-year warranty, providing assurance of build quality and sustained performance over the service life expected of a medium-tier EFB product.

A. EFB stands for Enhanced Flooded Battery. It incorporates a polyester scrim layer within the positive plate construction, which improves charge acceptance and cyclic durability compared to a conventional flooded lead-acid battery. This makes it better suited to start-stop applications where the battery is discharged and recharged more frequently.
A. Yes. The 100EFB is purpose-built for start-stop applications. It is designed to withstand the repeated charge and discharge cycles associated with start-stop systems and to support vehicle auxiliary loads during engine-off periods.
A. The battery measures 277mm in length, 174mm in width, and 175mm in height including the terminal. Always verify these dimensions against your vehicle's battery tray before ordering.
A. The 100EFB uses a Type 1 terminal configuration with polarity 0, meaning the negative terminal is positioned to the left when viewed from the front of the battery. It uses a B13 hold-down arrangement.
A. The battery is supplied in an LB3 case format. This is a standard European battery case group. Confirm your vehicle's required case group using your owner's manual or a fitment guide before purchase.
A. EFB batteries are not a like-for-like replacement for AGM batteries. If your vehicle was factory-fitted with an AGM battery, it should be replaced with an AGM unit. Substituting an EFB for an AGM may result in reduced performance and could affect battery management system operation.
