Overview

The Garmin 010-11864-00 is a rechargeable lithium-ion battery pack for select Garmin dog training handheld transmitters. It is commonly carried as a spare or installed as a replacement when the original battery no longer holds a charge.

In normal use, it can run for about 3 months per charge, which is handy when you are away from shore power for a few days. This battery powers the handheld internally and does not wire into a boat’s 12V or 24V system.

Key features

• Rechargeable lithium-ion battery pack for compatible Garmin dog training handheld transmitters
• Works as a replacement battery or an extra battery to keep a handheld running longer between charges
• Typical battery life is about 3 months per charge, depending on how the handheld is used
• User-replaceable format for handheld units that use this battery style
• Good to keep onboard in a dry kit as backup power for your handheld

Compatibility and fit

This battery is used in Garmin Delta series handhelds (including Delta, Delta Sport, Delta Upland, and Delta XC models) and the PRO Control 2 handheld. Match the part number to your handheld’s battery to confirm fit before ordering, since Garmin uses different battery packs across different product families.

It is a good match for boaters who keep a Garmin training handheld on board for dockside practice, beach walks, or trips where charging opportunities are limited.

Installation and setup

Installation is a straightforward swap inside the handheld. Power the unit off, open the battery compartment, replace the battery pack, and make sure the connector seats fully before closing the case. After installing, charge the handheld fully before heading out so you start with a known battery level.

Use cases on board

Carrying a charged spare helps when you are training at the dock, moving between the boat and shore, or spending long days away from an outlet. It also makes sense as a backup if the handheld is part of your routine gear and you do not want a dead battery to end a session early.

Maintenance and storage

Keep the battery and contacts clean and dry, especially around salt spray. For longer storage, keep it in a cool, dry place and top it up periodically so it is ready when you grab the handheld for the next trip.
