Mostly to Mazda Bt-50 Pickup (1 orders with the vehicle identified). Treat this as guidance, not confirmation: size and positive-terminal side depend on the exact version.
ER450 vs Exide ER350
The Exide ER450 offers 95 Ah and 720 A cold cranking in a 306 × 173 × 222 mm case. The Exide ER350, same brand and technology, stays at 80 Ah and 570 A with 36 mm less length and costs €4.30 less. If your car originally had the smaller capacity, this one gives extra reserve in the same case.

Marine battery Exide ER450 Marina Dual Er 95Ah 720A 12V
The Exide ER450 marine battery offers 12 V, 95 Ah and 720 A of cold cranking current (EN) from the Marina Dual Er range with conventional lead-acid technology, designed for motor and sailing boats, both for engine starting and onboard services. Its 306 × 173 × 222 mm and the positive terminal on the left make it the exact replacement for the 95 Ah battery fitted as standard to many boats.
- Ready for starting outboard and inboard engines.
- Good balance of capacity, cranking power and price.
- Resistant to humidity and salt air.
- Sealed: no spills or gases in the locker.
What the Exide ER450 is for
The Exide ER450 is designed for motor and sailing boats, both for engine starting and onboard services. If it is your starter battery, run the services from a separate battery; if it is a service battery, avoid routinely discharging it beyond 50%. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 21.70 kg, 1 terminals and Korean B1 hold-down.
Will it fit your current battery tray?
It has external dimensions of 306 × 173 × 222 mm and weighs 21.70 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 Korean B1 hold-down and 1 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.

The Exide ER450: Marina Dual Er range and conventional lead-acid technology
The ER450 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.
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.
How to make it last longer
As a service battery, avoid routine discharges below 50% to extend its cycle life. At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up.
Manufacturer's warranty
The Exide ER450 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.
When you get it and how to return it
Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 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 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

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 dimensions of the Exide ER450 battery?
The Exide ER450 takes up 306×173×222 mm (length, width and height, terminals included). Before buying, measure the space in your boat: one extra millimetre can stop the hold-down clamp from closing.
Which side is the positive terminal on this battery?
It has the positive on the left (polarity). It must match your current battery: reversed polarity means lengthening cables or reconfiguring the system, with a risk of short circuit. Put it in front of you, terminals towards you: the post with the red ring and the + sign is the positive.
