A. The Exide EZ850 has a rated capacity of 100Ah at the C20 discharge rate, meaning it can deliver 5 amps continuously over 20 hours before reaching its discharged threshold.
A. The EZ850 is rated at 900A CCA to the EN standard, providing reliable engine starting performance in cold conditions typical of UK and Northern European marine environments.
A. EFB stands for Enhanced Flooded Battery. A polyester scrim mat is bonded to the active plate material, reducing mass shedding during repeated cycling. This makes the EZ850 more durable than a standard flooded battery when subjected to the frequent partial discharge and recharge cycles common in marine leisure applications.
A. The EZ850 has standard polarity (polarity code 0), meaning the positive terminal is positioned on the left when the battery is viewed from the front with terminals facing upward. Confirm terminal layout against your vessel's existing wiring before installation.
A. The battery measures 353mm in length, 175mm in width, and 190mm in height including terminals. It is housed in an L05 case with a B13 hold-down type. These dimensions should be verified against the battery tray on your vessel before ordering.
A. The EZ850 is certified to NCC Class B. The National Caravan Council battery classification scheme rates batteries on their suitability for leisure use. Class B indicates the battery is suitable for moderate leisure demands and provides a standardised benchmark for comparing batteries across manufacturers.
A. The EFB technology used in the EZ850 is capable of supporting start-stop functionality; however, suitability for a specific start-stop system must be verified against the product label and the vessel manufacturer's battery specification. Do not assume compatibility without confirming the required battery technology and capacity for your application.
A. Yes. Related models within the Exide Dual EFB and EZ ranges include EL700, EL752, EL754, EL800, EL954, EL955, EL1000, EL1050, and EZ600, covering a range of capacities and dimensions to suit different vessel battery tray configurations and electrical load requirements.
A. The EZ850 is dispatched via standard parcel delivery. Orders to UK mainland addresses are typically delivered within 1–3 working days. A 30-day returns policy applies. Delivery timescales to offshore, Highland, or non-mainland UK destinations may differ; contact PartsForMachines for confirmation before ordering.
A. The EZ850 carries a Watt-Hour rating of 850Wh. This figure represents the total energy the battery can deliver and is particularly useful when calculating how long onboard consumers — such as navigation electronics, lighting, or bilge pumps — can run from the battery without engine charging.
