• Tolerates the daily cycling of a boat in season.
• Powers onboard services: lights, sounder, GPS, fridge.
• Reinforced case against vibration and swell.
• EFB technology: reinforced electrolyte for many more start cycles.

What the Tudor TZ650 is for

With 75 Ah, the Tudor TZ650 covers motor and sailing boats, both for engine starting and onboard services. At the end of the season, charge it fully before winter storage. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 19 kg, EN taper post terminals and B00 hold-down.

Technology inside the Tudor TZ650

Tudor builds the TZ650 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.

EFB combines the robustness of the flooded battery with improved plates and separators. The result is a clearly longer service life in vehicles that start and stop constantly.

Size, terminals and hold-down of the Tudor TZ650

It has external dimensions of 260 × 173 × 222 mm and weighs 19 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 B00 hold-down and EN taper post terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

Tudor: the maker behind the TZ650

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

As a service battery, avoid routine discharges below 50% to extend its cycle life. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections.

Warranty and coverage

The Tudor TZ650 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.
