How to Store Batteries

Getting the best performance from your STIHL battery-powered tools relies on the care you give your batteries. Follow these storage instructions to keep your batteries working at their best level for years to come. Note: These instructions are intended as a guide. Refer to your battery and tool instruction manuals for manufacturer recommendations on storage.

Prepare the Battery

Make sure your batteries are ready to go to work and provide top performance to your tools when you follow these storage instructions.

• Make sure the battery is clean and dry, in accordance with the manufacturer’s instructions.
• Store out of reach of children.
• Store away from direct sunlight in a secure, dry area at temperatures no lower than 14°F and no higher than 122°F.
• For maximum battery life, store the battery at an ambient temperature between 50°F and 68°F, with a charge between 40% (two green LEDs) and 80% (three green LEDs).
• Do not leave spare batteries unused. Use them in rotation.

For Integrated Battery Tools

Tools that feature an integrated battery require a different storage method.

• Switch off the tool and remove the activation key.
• Make sure the tool is clean and dry, in accordance with the manufacturer’s instructions.
• Store tool in a dry, secure place out of reach of children and other unauthorized users.
• Store the activation key separately away from the tool and out of reach of children and other unauthorized users.
• For maximum battery life, store the tool and integrated battery at an ambient temperature between 50°F and 68°F with a charge between 40% and 60% (two green LEDs). If the tool is stored above 86° F, its run time and performance may be reduced.
• Before storing, always unplug the charger from the wall outlet and remove the charger from tool.

True or False?

Q: A STIHL battery should be fully charged before storage.

A: False.

Lithium-ion batteries feature modern technology with a low level of self-discharge when compared to rechargeable batteries of the past. Lithium-ion batteries are designed to protect cells from deep discharge. Thanks to separate integrated fuses, the battery will automatically switch to an idle state. It's best to store a STIHL battery with a 40% to 80% charge (two or three lit LED lights) remaining for maximum life of the battery.
