Truck battery Tudor TJ165A1 Start PRO (Hd) 165Ah 850A 12V

The Tudor TJ165A1 with conventional lead-acid technology delivers 165 Ah at 12 V and 850 A of cold cranking current (EN): what trucks, buses, tractors and heavy machinery demand. It replaces the original battery without adaptation in trucks with a 354 × 241 × 285 mm format: same 165 Ah capacity.

• Powerful cold cranking for large-displacement diesel engines.
• Designed for 24 V installations with two batteries in series.
• Conventional lead-acid: the most proven and economical technology.
• Heavy Duty construction for intensive professional use.

What the Tudor TJ165A1 is for

Designed for trucks, buses, tractors and heavy machinery, the Tudor TJ165A1 withstands constant chassis vibration and discharges during stops with active loads. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 45.30 kg.

The Tudor TJ165A1: Start PRO (Hd) range and conventional lead-acid technology

Within the Tudor catalogue, the Start PRO (Hd) series groups the references designed for this use. The TJ165A1 is the 165 Ah model of that family, with the same performance as its siblings in other sizes.

Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour.

Size, terminals and hold-down of the Tudor TJ165A1

The Tudor TJ165A1 is made in the 354 × 241 × 285 mm format and weighs 45.30 kg. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.

What Tudor does differently

Tudor has made batteries in Spain for more than a century and remains one of the brands most trusted by Spanish workshops for reliability and value. All the Tudor batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

Usage and maintenance tips

Keep the terminals clean and tight and the battery firmly secured against chassis vibration. During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery.

Manufacturer's warranty

The Tudor TJ165A1 comes with the manufacturer's official warranty against manufacturing defects. An important note for commercial vehicles: most trucks use two batteries connected in series (24 V installation). If you replace only one, the new battery works alongside the old one, which has already lost capacity; that imbalance shortens its life and the manufacturer may treat it as misuse. Always replace both at the same time.

Shipping, delivery and returns
