Marine battery Exide EM900 Marina Start AGM 42Ah 700A 12V

The Exide EM900 with AGM technology is a marine battery with 42 Ah and 700 A of cold cranking current (EN) for motor and sailing boats, both for engine starting and onboard services. Measuring 230 × 173 × 206 mm, it is the direct replacement for boats fitted from the factory with a 42 Ah battery of this format.

• AGM: faster recharging and better cycle resistance than a conventional battery.
• Ready for starting outboard and inboard engines.
• Sealed: no spills or gases in the locker.
• Resistant to humidity and salt air.

What the Exide EM900 is for

The Exide EM900 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 15.80 kg, SAE M 3/8"- 5/16"&stud terminals and B7 hold-down.

The Exide EM900: Marina Start AGM range and AGM technology

The EM900 is part of the Exide Marina Start AGM 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 an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.

Dimensions, polarity and mounting

The Exide EM900 is made in the 230 × 173 × 206 mm format and weighs 15.80 kg. It uses a B7 hold-down and SAE M 3/8"- 5/16"&stud 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.
