Storing EGO batteries for winter comes down to three things: take the battery off the tool, leave it partly charged (around 30 to 50 percent, not full and not empty), and keep it somewhere cool and dry that stays above freezing. Inside the house is the safest spot; a closet or basement shelf works well. A garage is fine only if it stays dry and does not drop below freezing, which rules out most unheated garages and sheds in Indiana and Ohio by January. The tools themselves are less fussy, but a clean, dry space off the floor keeps them ready for spring. Here is the full checklist we give Customers at our stores across Indiana and Ohio.
Why Winter Storage Matters
EGO Power+ tools are built to handle hard work, but a lithium-ion battery left in a cold garage, or sitting dead in a mower all winter, loses capacity it will not get back. Moisture does the rest: rust on blades, corrosion on contacts. A few minutes of prep now can save you a battery replacement later.
Preparing Your EGO Power+ Tools for Storage
Before anything goes on the shelf:
- Clean your tools: Wipe them down with a soft, damp cloth, paying attention to air vents and moving parts where clippings pack in. Do not hose them down or use harsh chemicals.
- Inspect for damage: Look for loose screws, cracked housings, or worn blades. Fix them now so a small problem does not become a bigger one by spring. Our parts team can match replacements to your model.
How to Store EGO Batteries Over the Winter
The battery is the expensive part, and it is the part most people get wrong.
- Charge to about 30 to 50 percent: A full charge strains the cells over months of sitting; a fully drained battery can drop so low the charger will not revive it. Check your battery's manual for the exact level EGO recommends for your pack.
- Remove it from the tool: Pull the battery out of the mower, trimmer, or blower before storage. It prevents slow drain and keeps the contacts clean.
- Keep it dry and between 32 and 80 degrees Fahrenheit: Cold is the main enemy. A spot that stays above freezing and away from heat sources like a furnace or water heater is ideal.
- Check it once a month: If the charge indicator has dropped, top it back to the storage level.
Is it safe to store EGO batteries in the house?
Yes. A dry closet, basement shelf, or utility room is the best place for them. Keep them off concrete floors, away from heat sources, and out of reach of kids.
Can EGO batteries be stored in the garage?
Only if the garage stays above freezing and dry all winter. Attached, insulated garages often do; detached garages and sheds usually do not. If you are not sure, bring the batteries inside and leave the tools in the garage. Never store a battery in a vehicle.
Storing the Mower and Other EGO Tools
- Choose a dry spot: A garage, basement, or shed is fine for the tools themselves as long as it stays dry. Freezing hurts batteries far more than it hurts the tool.
- The mower: Remove the battery, clean under the deck, check the blade, and fold the handle if your model allows it so it stores upright and takes less floor space. Cover it if the space is dusty.
- Prevent physical damage: Put trimmers, blowers, and chainsaws on sturdy shelves or hang them on hooks so nothing gets knocked off.
Reactivating Your Tools for Spring
- Inspect tools and batteries for wear, cracks, or corrosion on the contacts.
- Fully charge the batteries before the first use.
- Run each tool for a minute to confirm it works before the first real job.
If a battery will not take a charge after a winter indoors, bring it to your nearest store and we will test it before you buy a new one.
Common Mistakes to Avoid
- Leaving the battery in the mower in an unheated garage all winter.
- Storing batteries full or dead instead of partly charged.
- Skipping cleaning, which lets damp clippings cause rust and corrosion.
- Charging a battery that is still cold from the garage. Let it warm to room temperature first.
