The **Tudor TZ600 marine battery** offers **12 V**, **70 Ah** and **760 A** of cold cranking current (EN) with EFB technology, designed for motor and sailing boats, both for engine starting and onboard services. It measures 278 × 175 × 190 mm and the positive terminal on the right, the format sought by anyone replacing a 70 Ah battery in boats.
- 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 TZ600 is for

With 70 Ah, the Tudor TZ600 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 19.30 kg, EN taper post terminals and B13 hold-down.

### Dimensions, polarity and mounting

It has external dimensions of 278 × 175 × 190 mm and weighs 19.30 kg. The positive terminal on the right 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 B13 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.

### Technology inside the Tudor TZ600

Tudor builds the TZ600 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.

### Tudor: the maker behind the TZ600

Tudor is Spain's historic battery brand, today part of the Exide group. Its car, truck, motorcycle and leisure ranges are built with the same technology and controls as the group's original-equipment references. We guarantee that every Tudor arrives new, charged and with the manufacturer's full warranty.

### Warranty and coverage

The Tudor TZ600 comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

### Care and maintenance

A charger with an EFB or smart conventional mode is enough; avoid the high-voltage modes intended for AGM. As a service battery, avoid routine discharges below 50% to extend its cycle life.

### When you get it and how to return it

Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

## Frequently asked questions

### How do I fit the TZ600 model in my boat?

In most boats it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On boats with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

### How long does the Tudor TZ600 battery last?

Expected lifespan of the Tudor TZ600 is 4 to 7 years in regular use (depends on technology and climate). In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.

### What are the dimensions of the Tudor TZ600 battery?

Dimensions (length × width × height) are 278×175×190 mm — also written as 278x175x190 mm and correspond to the European L3 case size — following the European DIN standard. Always measure the space in your boat before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.

### Will the Tudor TZ600 battery fit my boat?

Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The TZ600 typically fits a wide range of European vehicles thanks to its standard DIN case format.

### Which batteries are equivalent to the Tudor TZ600?

Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop boats. See the "Equivalents" section to view recommended options at the same performance level.
