Storing Your Powerhouse Lithium Batteries for Winter

With the arrival of colder weather, it’s essential to properly store your Powerhouse Lithium batteries to ensure their longevity and optimal performance for years to come.

Here are some guidelines to help you winterize your lithium batteries:

General Recommendations

Optimal Storage Temperature: Keep your batteries in a cool, dry place, away from direct sunlight and extreme temperatures. The ideal storage temperature is above 50°F.
Pre-Storage Charging: Charge your batteries to 80% capacity before storing them. This helps maintain battery health and ensures they’re ready for the next season.
Battery Inspection and Cleaning: Before storing, examine the battery case for any damage or cracks. Never charge batteries with damaged cases. Clean the battery with a dry cloth to remove dirt or residue.
Freezing Temperatures: If temperatures fall below freezing, it’s best to remove your batteries from storage. You can also use a 60-watt incandescent light bulb in the battery compartment to keep the temperature above 32°F. Do not use an LED bulb.

If Batteries Remain Onboard

Terminal Disconnection: Disconnect the battery terminals to prevent onboard electronics from gradually draining the battery during the off-season.
Moisture Prevention: Store the battery in a dry location within the boat, ensuring no risk of condensation buildup.

Specific Instructions for Ice Fishing Batteries

Periodic Charging: Charge your PHL Ice batteries every four months during periods of inactivity.

Important Reminders

Ideal Storage Voltage: Aim for a voltage between 3200 and 3300 mV for storage. You can check this on your cell page.
Turn Off All Loads: Ensure all loads are turned off before storing your batteries to prevent self-discharge.
Safe Mode Warning: If your battery enters “safe mode” (0% State of Charge), you have two weeks to recharge it. Otherwise, the Battery Management System (BMS) will become unresponsive and may require a service fee to repair.

By following these winterization guidelines, you can ensure the reliable performance of your Powerhouse Lithium batteries for many seasons to come!
