SECTION 2: Hazards identification

3.1 Overview Battery cells are hermetically sealed. A battery is safe in use provided the manufacturer’s recom‐ © mendations are observed. WARNING ANDREAS ■ Chargers not explicitly approved by STIHL for a battery or products with a built-in battery SI_002_2017_01_01. STIHL may cause a fire or explosion. Persons may AG be seriously or fatally injured and property & may be damaged. VA5.L21. Co. KG 2021 SI_002_2017_01_01 ► Recharge batteries or products with a built- in battery only with a charger approved by STIHL for the battery or the product with a built-in battery. WARNING ■ A battery or product with built-in battery cannot operate reliably if it is not in a safe condition. They may cause serious injury to persons. ► Never bridge a battery's contacts with met‐ allic objects (short circuit). ► Do not insert objects in openings in the bat‐ tery or product with built-in battery. ► Do not attempt to open batteries or prod‐ ucts with a built-in battery. WARNING ■ Children are not aware of and cannot assess the dangers of a battery or a product with a built-in battery Children may be seriously injured. ► Keep children away. WARNING ■ A battery or a product with a built-in battery is not protected against all ambient influences. A battery or a product with built-in battery may be damaged if it is exposed to certain ambient influences. ► Always store a battery or product with built- in battery in a clean and dry condition. ► A STIHL AP, AR L battery may be used in the rain. Do not immerse the battery in flu‐ ids. ► Protect a STIHL AR 900, 1000, 2000, 3000 battery from rain and moisture and do not immerse it in liquids. For AR 1000, 2000, 3000 only: Use a rain cover in rainy weather. ► Protect a STIHL AK, AS battery or product with built-in battery from rain and dampness and do not immerse in fluids. Robotic mow‐ ers may be used in the rain. Never immerse a robotic mower in water or liquids. ► Observe the permissible temperature range for the battery or product with a built-in bat‐ tery. ► Store STIHL AAI battery only in the robotic mower. ► Protect a battery or product with built-in bat‐ tery from heat and open fire. ► Never throw a battery or product with built- in battery in a fire. ► If the battery emits fumes, heats up, smells, makes noises or shows signs of deforma‐ SI_002_2017_01_01 Batteries or products with a built-in battery are safe in use when handled properly under the conditions recommended by the manufacturer. Leakage and the escape of battery contents and products of decomposition may be caused by mistreatment or circumstances resulting in irreg‐ ular operation. In principle it can be assumed that contact with battery ingredients represents a risk to health and the environment. Therefore, adequate body protection and breathing protection must be worn before any contact with suspicious batteries (leakage of contents, deformation, discoloration, bulges or similar). Batteries may react very vio‐ lently, e.g. when they come in contact with fire. In such a case battery contents can be expelled at high velocity. 3.2 Handling and Operating Safety Batteries and products with a built-in battery must always be handled according to the manu‐ facturer's recommendations. This applies in par‐ ticular to observing the limits for thermal loads during storage and transport. Maximum temperature range – up to +100°C (+212°F) Permissible temperature range for operation, transport and storage – STIHL AS battery: - 20°C to +50°C (- 4°F to +120°F) – STIHL AK , AP, AR , AR L batteries: ‑10°C to +50°C (14°F to +120°F) – STIHL AAI battery: 0°C to +50°C (+32°F to +120°F) – STIHL BGA 45, FSA 45, HSA 45: 0°C to +50°C (+32°F to +120°F) – Battery for STIHL HSA 25: 0°C to +40°C (+32°F to +105°F) STIHL batteries, products with a built-in battery and STIHL chargers are placed on the market together as matching product packages. The bat‐ teries or products with a built-in battery and chargers must not be modified or tampered with in any way. The STIHL AAI battery is intended exclusively for fixed installation in a STIHL robotic mower. It is ideally protected there and recharged when the robotic mower is in the docking station. English Use STIHL batteries only with STIHL or VIKING power tools and charge STIHL batteries or prod‐ ucts with a built-in battery only with the designa‐ ted STIHL chargers. Never charge or use a defective, damaged or deformed battery. Never charge or use a defective, damaged or deformed product with a built-in battery. Even in an apparently discharged state, batteries or products with a built-in battery can continue to be a source of danger and deliver a very high short circuit current.
