Marine battery Exide ER600 Dual 120Ah 800A 12V
With 120 Ah at 12 V and 800 A of cold cranking current (EN), the Exide ER600 from the Dual range is built for motor and sailing boats, both for engine starting and onboard services. It replaces the original battery without adaptation in boats with a 349 × 175 × 285 mm format: same 120 Ah capacity and the positive terminal on the left.
- Conventional lead-acid: the most proven and economical technology.
- Reinforced case against vibration and swell.
- Powers onboard services: lights, sounder, GPS, fridge.
- Tolerates the daily cycling of a boat in season.
What the Exide ER600 is for
On board, the Exide ER600 provides 120 Ah with a case reinforced against vibration and swell. Keep the terminals clean and protected from salt humidity. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 31.40 kg, EN taper post terminals and B0 hold-down.
Will it fit your current battery tray?
In terms of format, the Exide ER600 measures 349 × 175 × 285 mm (length × width × height) and weighs 31.40 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 B0 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.
The Exide ER600: Dual range and conventional lead-acid technology
The ER600 is part of the Exide Dual range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
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.
What Exide does differently
With more than a century of history, Exide Technologies manufactures automotive, marine, motorcycle and industrial batteries in Europe. Its presence as original equipment on assembly lines vouches for the quality of every reference. All the Exide batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
Warranty and coverage
The Exide ER600 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.
Care and maintenance
At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections.

Frequently asked questions
Is this a starting or a service (leisure) battery?
Dual purpose: it can start the engine and also work as a service battery, handy on boats with a single battery. On boats with two circuits the ideal is one starting battery and one service battery.
In what position can it be installed on the boat?
It must be mounted upright, firmly secured and in a ventilated compartment, because it gives off gases when charging. Keep the terminals away from salt water.
What are the measurements of the ER600 model?
Dimensions (length × width × height) are 349×175×285 mm — also written as 349x175x285 mm — 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.
On which side is the positive of the ER600 model?
Polarity: positive on the left. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk.
