Overview

The Garmin 010-11874-00 is a rechargeable NiMH battery pack for select Garmin handheld GPS units, letting you run a dedicated pack instead of two AA batteries.

On a boat, a handheld often ends up as the grab-and-go backup at the helm, the tender navigator, or the unit that lives in a ditch bag. This pack keeps that handheld ready and cuts down on last-minute battery swaps. It recharges while the compatible handheld is connected to USB power or an AC adapter, so topping up from a 12 V USB outlet or a power bank is straightforward.

Key features

• Replaces two AA batteries in compatible Garmin handhelds for a cleaner, all-in-one rechargeable setup.
• Charges inside compatible devices while the handheld is connected to an AC adapter or a USB power source.
• Works with GPSMAP 64 family handhelds (including 64, 64s, 64st and 64x variants) and Oregon 600 family handhelds (600, 600t, 650, 650t).
• Also listed for GPSMAP 65 series, GPSMAP 66s and 66st, Oregon 700 series (700, 750, 750t), and Astro 430 and Astro 900 handhelds.
• Helps keep a cockpit or on-deck handheld topped up between runs without managing loose AA cells.
• Intended to be charged by the compatible handheld, not by external standalone chargers.

Compatibility and fit

This pack is made to fit the battery compartment used by Garmin handhelds that accept the optional NiMH pack. Common matches include GPSMAP 64, 64s, 64st, 64sx and 64x models, plus Oregon 600, 600t, 650 and 650t. It is also listed for GPSMAP 65 and 65s, GPSMAP 66s and 66st, Oregon 700, 750 and 750t, and Astro 430 and Astro 900 handhelds.

Confirm your exact handheld model before ordering. Garmin handheld families that look similar can use different battery bays, and this pack is not meant as a universal fit for older GPSMAP or Oregon generations.

Charging and power on board

Charging happens through the handheld. Connect the device to USB power or an AC adapter and the pack charges while installed. On some setups you may need to remove a mount or accessory to access the handheld’s USB port.

Charging can pause if the handheld is outside its approved charging temperature range. If the unit has been sitting in direct sun in the cockpit or stored in a cold locker, letting it return to a normal temperature can restore charging behavior.

Who it suits

This pack makes sense if you keep a Garmin handheld ready for backup navigation, anchorage checks from the bow, dinghy runs, or shore-side exploring on cruising days. It also fits anglers who run a handheld for long stretches and prefer recharging between trips over replacing AA batteries.

Care and storage

For longer storage periods, remove the pack from the handheld and keep it in a dry place. Keep the battery compartment clean and avoid salt spray and moisture around the contacts so the pack seats fully and the door closes properly.
