Tudor TG1705 · Truck battery 12V 170Ah 950A

Truck battery Tudor TG1705 Start PRO (Hd) 170Ah 950A 12V

The Tudor TG1705 with conventional lead-acid technology delivers 170 Ah at 12 V and 950 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 514 × 218 × 210 mm format: same 170 Ah capacity and the positive terminal on the left.

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

What the Tudor TG1705 is for

With 170 Ah, the Tudor TG1705 cranks large-displacement diesel engines in the cold and powers tachograph, fridge and heater during rest stops. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 42.50 kg, EN taper post terminals and B3 hold-down.

Dimensions, polarity and mounting

In terms of format, the Tudor TG1705 measures 514 × 218 × 210 mm (length × width × height) and weighs 42.50 kg. The positive terminal on the left decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses a B3 hold-down and EN taper post terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

Tudor: the maker behind the TG1705

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. We guarantee that every Tudor arrives new, charged and with the manufacturer's full warranty.

The Tudor TG1705: Start PRO (Hd) range and conventional lead-acid technology

The Start PRO (Hd) is the Tudor range the TG1705 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.

The conventional lead-acid battery remains the most widespread technology thanks to its balance of capacity, cranking current and price. Well maintained and kept charged, it offers years of reliable service in vehicles without Start-Stop.

How to make it last longer

Keep the terminals clean and tight and the battery firmly secured against chassis vibration. On batteries with filler caps, check the electrolyte level and top up only with distilled water.

Warranty and coverage

The Tudor TG1705 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.
