Attwood Marine Marine & Automotive Battery Charger, 12V/6V, 2A/6A, Automatic Trickle Charge

Overview

The Attwood Marine 11901-4 is a portable battery charger for 6V and 12V batteries, with 2A and 6A charge settings for 12V batteries and a 6A setting for 6V batteries. Once the battery reaches full charge, it switches to trickle mode, which makes it useful for routine charging and for keeping a battery maintained during storage.

This charger fits the kind of battery care many boat owners handle off the water, at the dock, or while the boat is on the trailer. The front ammeter lets you watch charging current as the battery comes up, and the LED power light gives a quick visual check that the unit is on. A 6 foot AC power cord and 48 inch battery leads also give some working room around a battery box, garage bench, or shop cart.

Key features

• Charges 12V batteries at 2A or 6A, and 6V batteries at 6A
• Shifts to trickle charge automatically after the battery is fully charged
• Built-in protection for overcharge, short circuit, and reverse polarity
• Front ammeter shows charging current during use
• LED indicator shows when the charger has power
• Includes a 6 foot power cord and 48 inch battery connector leads
• Suited to marine, automotive, RV, and similar battery maintenance tasks

Compatibility and fit

This unit is a practical match for owners charging a single 6V or 12V battery, whether that is a boat battery between trips, a seasonal battery in storage, or a battery that is removed for service. It is not the right charger for a 24V bank charged as a full 24V system, so checking battery voltage before hookup matters on boats with more than one battery or with series-wired banks.

For marine use, it makes the most sense where charging happens at home, in the marina, or in a workshop rather than through a built-in onboard charging setup. Small fishing boats, trailered boats, tenders, and other simple electrical setups are the kind of applications where this style of charger usually fits best.

Installation and setup

Connection is straightforward: attach the clips with correct polarity, choose the charge rate, and monitor the ammeter as charging begins. The reverse polarity protection adds some margin during hookup, which is helpful when working around battery compartments and storage areas where access can be tight.

As with any battery charger, use it in a ventilated area and confirm the battery voltage before charging. That is especially important on boats that may have separate starting and house batteries, or older 6V batteries kept for specialty equipment and seasonal gear.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
