Charging STIHL Lithium-Ion Batteries

HOW LONG DO I NEED TO CHARGE A NEW STIHL BATTERY?

Say goodbye to overnight charging! With STIHL's advanced Lithium-ion batteries, you can say goodbye to the hassle of having to charge your batteries overnight before use. Unlike older Nickel-cadmium batteries, Lithium-ion batteries are protected against self-discharge, so you can start using them right away. Plus, our STIHL batteries come pre-charged to 30%, so you can start your project as soon as you buy it.

PROTECTION FROM SELF DISCHARGE

The electronic system of a STIHL Lithium-ion Battery automatically puts the battery into an idle state, when it has not been used for a long time. This protects against harmful discharge.

OVERHEATING BATTERIES

As users become increasingly aware of the potential risks associated with battery usage, it's important to address concerns head-on and provide peace of mind. At STIHL, we understand the importance of safety and have implemented measures to ensure our Lithium-ion Batteries are both reliable and secure.

When charging, it's normal for a battery to generate some heat, however, our STIHL Batteries feature a built-in battery management system that prevents overheating by stopping the charging process when the battery reaches full capacity. This ensures the safety and longevity of your battery, making it a reliable and dependable power source for your tools.

Additionally, our Lithium-ion batteries are housed in robust, flame-retardant casing, providing an extra layer of protection against overheating. This allows you to use our batteries with confidence and peace of mind, knowing that they've been engineered to meet the highest safety standards.

STIHL LITHIUM-ION BATTERIES MEET THE HIGHEST SAFETY STANDARDS

Both the STIHL Batteries and Chargers are equipped with protective mechanisms that prevent overcharging and excessive heat.

MONITORING BATTERY TEMPERATURE

Every single cell installed in a rechargeable Battery is monitored by a battery management system. An integrated sensor measures the temperature at the warmest point inside the Battery - if the temperature is too high, the charging process is interrupted. The Battery and Charger continuously exchange data: once a charge level of around 80% has been reached, the charger automatically reduces to a very low and gentle charging current. When the Battery is fully charged, the charger automatically ends the charging process and the circuit is interrupted.

PROTECTING BATTERIES FROM EXTREME EXTERNAL TEMPERATURES

We recommend that our cordless tools and batteries be stored indoors and at moderate temperatures to ensure optimal charging and performance. Our STIHL Batteries are designed to be safely charged when the air temperature is between +5 to +40 degrees Celsius. A garage or shed, where the temperature remains within this range is ideal for both storage and charging.

EXTREME HEAT

A modern Lithium-ion Battery consists of an anode, a cathode, a separator and the electrolyte. Electrolyte is a chemical compound that has a liquid or gel-like state. This material ensures the transport of the electrically charged particles (ions) between the anode and cathode. If the temperature is too high, the ions move between the anode and cathode too quickly and the material decomposes - the Battery then becomes unusable.

EXTREME COLD

Temperatures that are too low are also harmful to the Battery. Unlike when the particles accelerate in heat, the processes slowdown in the cold. A frozen battery cannot be charged at all.

THE CHARGE LEVEL INDICATOR ON STIHL BATTERIES

The four LEDs on the Battery indicate the charge status of the Battery and any faults. Simply press the button on the battery - the LEDs light up green for about five seconds and then indicate the charge status by the number of green bars that are displayed. If only one LED flashes green, this indicates a low charge. If the LEDs light up or flash red instead, there is a fault.

If the Battery is in the charger, the green LEDs also indicate the charge status (if no LED lights up, the charging process is complete.)
