Keep corrosive, flammable and easily combustible objects clear of the battery charger and the battery. Do not cover the battery charger and the battery while charging. Disconnect the battery charger immediately in the event of smoke formation or fire. Only use the original GARDENA Charger to charge the battery. The use of other battery chargers may damage the batteries irreparably and even cause a fire. If you notice fire: Extinguish the flames with oxygen-reducing materials.
WARNING! Risk of explosion!
Protect batteries from heat and fire. Do not leave on radiators or exposed to strong sunshine for long periods. Do not operate in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Batteries may create sparks that could ignite dust or fumes. Check your replacement battery before each use. Visually check the battery before each use. A non-functioning battery must be disposed of correctly. Do not send by post. For further details, please contact your local disposal companies. For risks of injury do not use the battery as a power source for other products.

Check the charging cable regularly for signs of damage or aging (brittleness). Only use it in perfect condition. Do not store the battery above 45 °C or in direct sunlight. Ideally, the battery should be stored below 25 °C so that self-discharge is low. Do not expose the battery to rain or wet conditions. Water entering a battery will increase the risk of electric shock. Keep the battery in order (clean) especially air vents. If usage of the battery is not planned for a certain time (winter period) reload the battery to avoid a deep discharge.
