Large diesel engines, long stops with heaters running and constant vibration make heavy-duty batteries a category of their own. This section brings together starter batteries for HGVs, coaches, tractors, combines, telehandlers and earth-moving machinery.

Every product is filed under its maker and exact reference, which makes it straightforward to keep a fleet on identical parts. The tables list dimensions, post arrangement, amp-hours and EN cranking amps.

Choosing a battery for heavy vehicles

Begin with the original code or the cradle measurements, including the base ledge the clamp grips. Post type and layout vary far more on commercial vehicles than on cars, so check them next. Electrical ratings come last.

Points specific to lorries and machinery

24-volt systems: two 12-volt units wired in series are the norm, always renewed together as an identical pair.
Vibration: tractors and plant last longer with heavy-duty or vibration-resistant construction.
Overnight loads: bunk cabs with heaters and fridges call for plenty of amp-hours on top of cranking punch.

Quick answers

Why renew a series pair together?

Because an old partner pulls a fresh battery down to its own level and both fail early.

Laying up a machine between seasons?

Charge fully and disconnect, or keep a maintainer on it. A battery left half empty in a cold barn can lose capacity for good, and a frozen one may crack its case. Popular heavy-duty ranges come from Varta, Exide, Tudor and Deta.
