Who the Exide EX900 is for
The Exide EX900 is a battery for boats: engine starting or on-board service, depending on its design, with resistance to damp and hull vibration. Check whether your boat needs starting, service or a dual-purpose battery before choosing.
The EX900 belongs to the Exide EXIDE Maxxima range. More Exide batteries
Inside the EX900: AGM technology

How much does the Exide EX900 weigh?
17.9 kg, with 50 Ah of capacity. For reference, the Exide EP450 (50 Ah) weighs 18.6 kg.
Which battery is equivalent to the Exide EX900?

How do I look after the boat battery in winter?
Leave it 100% charged, disconnected or on a marine maintenance charger. A battery that spends the winter half-discharged loses capacity permanently.
