DANGER: Batteries Battery abuse or mishandling can cause the battery to overheat, which can cause gasses or flame to ″vent″ from the battery. Never attempt to open or service any battery. Do not crush, puncture, or incinerate the battery or short the metal contacts. Do not expose the battery to water or other liquids. Only charge the rechargeable battery pack pursuant to instructions included in the product's documentation. The battery pack can degrade when they are left unused for long periods of time. For some batteries (particularly Lithium Ion batteries), leaving a battery unused in a discharged state could increase the risk of a battery short circuit, which could shorten the life of the battery and can also pose a safety hazard. Do not let Lithium-Ion batteries completely discharge or, store these batteries in a discharged state. If your battery is damaged, or if you notice any discharge from your battery or the buildup of foreign materials on the battery leads, stop using the battery and obtain a replacement from the battery manufacturer. DANGER: Storing the rechargeable battery pack The battery pack should be stored at room temperature, charged to approx. 30 to 50 % of capacity. We recommend that battery pack be charged about once per year to prevent overdischarge. DANGER If the rechargeable battery pack is incorrectly replaced, there is danger of an explosion. The battery pack contains a small amount of harmful substances. To avoid possible injury: v Replace only with a battery of the type recommended by IBM. v Keep the battery pack away from fire. v Do not expose it to water or rain. v Do not attempt to disassemble it. v Do not short-circuit it. v Keep it away from children. Do not put the battery pack in trash that is disposed of in landfills. When disposing of the battery, comply with local ordinances or regulations and your company's safety standards. Appendix A.
