3805477 Battery Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for a battery. It is the refundable charge raised against the old battery when the exchange unit is bought, and it comes back once the worn battery is returned. The line itself is an accounting entry rather than a part, so nothing ships against it on its own. Under Volvo Penta's core numbering the exchange unit it belongs to takes part number 3802477, which is not a number we carry ourselves, so ask us to look the exchange unit up before you order against it. The other battery core listed here is 3805483, and nothing published against the two separates them, so order the deposit that matches the battery actually coming off. A returned battery is regulated for carriage rather than an ordinary parcel, so the return leg needs arranging with us before the old unit is sent.

⚙️ Key Features

• Core deposit line, not a battery you can fit
• Belongs with the exchange unit, part number 3802477
• Refunded when the old battery is returned
• Paired battery core 3805483 is not separable from it on anything published

🔌 Function

As a line item it carries the refundable core charge on the exchange; the battery itself holds the charge the vessel's systems draw on and gives it back on demand, taking it in again from the charging system.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the battery being exchanged
• Cranking gone slow and heavy, or the engine refusing to turn over after a night on the mooring
• Charge falling away far sooner than it used to, and the voltage sagging as soon as load comes on
• A case found swollen, split or weeping, or terminals corroded and warm to the touch
• Charging faults reported at the helm that stay after the charger and its cabling have been proved good

🛠️ Service Notes

• The charge is refunded when the worn battery is returned, so keep the old unit and send it back rather than scrapping it
• Ordering this number on its own supplies no part - it is the deposit that rides beside the exchange unit, part number 3802477, which we do not list ourselves, so ask us to look it up before ordering
• Batteries are regulated goods when they travel, so speak to us to arrange the return rather than sending the old one back on an ordinary parts label

📦 Condition

• Refundable core deposit - not a physical part
