Attwood 6V/12V 6A Portable Marine Battery Charger

The Attwood portable battery charger is designed for bench, garage, shop, and marine use when a permanently mounted onboard charger is not required. It can charge common low-voltage batteries and provides more than one charging rate so the user can choose a gentler charge or faster recovery when appropriate. Automatic control switches the charger to a maintenance-style trickle mode after the battery reaches full charge. That feature reduces the need to watch the charger continuously during normal service.

Built-in protection guards against overcharge, short circuits, and reversed battery connections. An ammeter on the front shows charging current, while a separate indicator confirms that AC power is present. A six-foot AC cord gives useful reach from the workbench or outlet, and the battery leads extend another 48 in to the battery connection point. The same charger can be used across marine, automotive, RV, and powersports batteries that fall within its supported voltage range.

• Automatic transition to trickle charge after full charge
• Protection against overcharge, short circuit, and reverse polarity
• Front ammeter displays charging current
• Six-foot AC power cord with 48 in battery leads

Place the charger in a dry, ventilated location and follow the battery manufacturer’s charging recommendations. Confirm polarity before connecting the leads and keep sparks or open flame away from batteries that may vent gas while charging.
