Overview
The Garmin 010-12881-05 is a rechargeable lithium-ion battery pack for Garmin Montana 700 series handheld GPS units, used as a direct replacement or a ready spare when you are away from a charger.
It is rated at 3100 mAh (11.8 Wh), which makes a noticeable difference when the handheld is doing all-day duty in the cockpit as a backup navigator, riding in the tender, or getting pulled out on deck to mark waypoints and fishing spots.
Carry a charged spare in a dry electronics pouch and swap it in through the battery compartment when the first pack runs low. On a boat, a second battery is often the simplest way to stay powered without having to keep the unit tethered to a charging cable.
Key features
- Compatible with Garmin Montana 700, Montana 700i, and Montana 750i handhelds.
- Rechargeable lithium-ion pack rated at 3100 mAh (11.8 Wh).
- Works as a replacement battery or a spare to extend runtime on long days on the water.
- Swaps through the battery compartment, so you can change packs even when you are off the dock.
- Practical for grab bags, kayaks, and small-boat kits where you want power on hand without relying on the boat’s wiring.
Compatibility and fit
This battery pack is intended for the Montana 700, Montana 700i, and Montana 750i. Match the model name on your handheld before ordering, since Garmin handheld batteries are not interchangeable across different device families.
Installation and on-board use
Open the battery compartment, remove the existing pack, and seat the replacement so it sits flat and the contacts align. Close and latch the door before heading back on deck. If you are swapping batteries underway, do it in a sheltered spot and keep the compartment clear of spray and salt.
Charging and care
Recharge the pack while it is installed in the handheld. For best battery life, avoid storing it in hot lockers or in direct sun, and top it up occasionally during off-season storage instead of leaving it fully discharged for long periods.
Use cases on board
This pack makes sense for boaters who keep a Montana as a backup to the fixed-mount plotter, and for crews who carry a handheld for dinghy runs, anchoring checks, and nearshore navigation where a spare battery is easier than hunting for a charging point.
