To winterize BUBBA lithium-ion electric fillet knife batteries in Canada, bring them indoors out of freezing garages, store them at roughly 40% to 60% charge in a cool 10°C to 20°C (50°F to 68°F) spot, and never charge a frozen battery until it warms to room temperature. Proper off-season care preserves runtime for your Pro Series Cordless Electric Fillet Knife, Lithium Ion Cordless Fillet Knife, and spare Magnum Lithium Ion Battery.
Why Canadian Winters Hurt Unattended Batteries
Boat lockers, cottage sheds, and detached garages regularly plunge to -25°C (-13°F) between November and March. While lithium-ion packs have no "memory effect," storing them completely drained in sub-zero air—or leaving them plugged into a charger all winter—accelerates internal cell degradation.
5-Step Off-Season Battery Checklist
- Remove Batteries From the Handle: Never store your Pro Series Cordless Electric Fillet Knife or Lithium Ion Cordless Fillet Knife with a battery latched inside the handle over winter.
- Clean & Dry the Contacts: Wipe away fish moisture or condensation with a clean dry cloth so metal terminals stay corrosion-free.
- Set a Storage Charge (40%–60%): Use the built-in LED battery life indicator—avoid storing packs at 0% empty or 100% topped off for months at a time.
- Store Indoors at Room Temperature: Keep packs in a dry basement closet or utility shelf between 10°C and 20°C (50°F and 68°F).
- Top Up Before Spring Opener: Give each pack—including any backup Magnum Lithium Ion Battery—a full charge the night before your first spring Walleye trip.
Ice-Fishing Tip: Warm Before Charging
If you use your cordless knife inside an ice shack, let cold batteries sit indoors for at least 60 minutes to reach room temperature before plugging in the charger.
