Marine battery Exide ER660 Marina Dual Er 140Ah 750A 12V
With 140 Ah at 12 V and 750 A of cold cranking current (EN), the Exide ER660 from the Marina Dual Er 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 513 × 189 × 223 mm format: same 140 Ah capacity and the positive terminal on the left.
In short: the Exide ER660 (140 Ah, 750 A, 513 × 189 × 223 mm, positive terminal on the left). Verified equivalent alternatives: Varta LFD140 and Exide EN900.
- Powers onboard services: lights, sounder, GPS, fridge.
- Tolerates the daily cycling of a boat in season.
- Conventional lead-acid: the most proven and economical technology.
- Reinforced case against vibration and swell.
What the Exide ER660 is for
With 140 Ah, the Exide ER660 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 37.30 kg, 1 terminals and B0 hold-down.
Dimensions, polarity and mounting
The Exide ER660 is made in the 513 × 189 × 223 mm format and weighs 37.30 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 1 terminals, the system that anchors and connects it in the vehicle. 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.
Why choose Exide batteries
With more than a century of history, Exide Technologies manufactures automotive, marine, motorcycle and industrial batteries in Europe.

The Exide ER660: Marina Dual Er range and conventional lead-acid technology
The ER660 is part of the Exide Marina Dual Er range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
In a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use.
Usage and maintenance tips
As a service battery, avoid routine discharges below 50% to extend its cycle life. On batteries with filler caps, check the electrolyte level and top up only with distilled water.
Manufacturer's warranty
The Exide ER660 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

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 ER660 model?
Measure your boat's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close. Length × width × height: 513x189x223 mm. Height is measured to the top of the terminals.
On which side is the positive of the ER660 model?
The ER660 has the positive on the left: that is its polarity. If your current battery has its positive on the other side, this one is not suitable without longer cables or a reconfigured system (short-circuit risk). Face the battery with its terminals nearest you and see which side the positive post (+, red ring) is on.
Exide ER660 or Exide EP1200: which one to choose?
It is the AGM of the same size: sealed, maintenance-free and with far more discharge cycles than the ER660. Compared with the ER660 it has 50 A of cold cranking less. It costs 31,70 € more. Recommended for cyclic or stationary use, or when the equipment sits tilted; for occasional use the ER660 does the job.
Exide ER660 or Exide EN900: which one to choose?
It is the bigger sister of the ER660 in the same Exide range. Compared with the ER660 it has 50 A of cold cranking more. It costs 97,80 € less. More capacity means more runtime: worth it if your equipment takes the size and had that capacity or more; otherwise the ER660 does the job.
