contains a small amount of harmful substances. To avoid possible injury:
• Replace only with a battery of the type recommended by Lenovo.

• Do not expose it to excessive heat.
• Do not expose it to water or rain.

cause the battery to overheat, which can cause gasses or flame to "vent" from the battery pack
or coin-cell battery.
