TUDOR SUPER HEAVY DUTY EFB Batteries

TUDOR SHD EFB: the Start-Stop range for heavy trucks

The TUDOR Super Heavy Duty EFB range uses EFB (Enhanced Flooded Battery) technology, a flooded lead-acid battery reinforced with additives in the negative plate paste and special separators that multiply resistance to charge and discharge cycling. It is the natural step up from a conventional SLI battery once the vehicle runs truck or bus Start-Stop, where the battery takes dozens of micro-starts a day on top of cold cranking.

Which vehicles the SHD EFB range is built for

• Rigid urban delivery truck with Start-Stop (SHD130 EFB, 130 Ah, 850 A).
• Medium-duty road tractor with Start-Stop (SHD180 EFB, 180 Ah, 1000 A).
• Heavy tractor unit with Live-Load systems and high standstill power draw (SHD220 EFB, 220 Ah, 1150 A).

Compatibility and how to choose your SHD EFB battery

Before buying, check the original battery of your truck or bus (Ah, CCA and polarity) against the vehicle spec sheet or OEM battery block: an EFB must match or exceed those figures to avoid losing cold cranking power or Start-Stop cycle life. Use our battery comparator to see Ah, CCA and price across the whole SHD EFB range at a glance and pick the exact reference for your fleet.

Frequently asked questions about TUDOR SHD EFB batteries

What is the difference between a truck EFB and a conventional SLI battery?

An EFB withstands far more start-stop cycles thanks to additives in its negative plates and reinforced separators, whereas an SLI battery is built for a single cold start per trip. In heavy-duty Start-Stop vehicles, the EFB lasts noticeably longer.

Is the SHD EFB compatible with any Start-Stop truck?

It is compatible as long as it matches or exceeds the Ah and CCA of the original battery and respects polarity and case dimensions. Within the range, SHD130, SHD180 and SHD220 cover everything from rigid trucks to heavy tractor units.

How long does a TUDOR SHD EFB last in fleet use?

Because it is built specifically for heavy Start-Stop cycling, it outlasts an equivalent SLI under that intensive use, which degrades sooner as it is not designed for repeated micro-starts.
