Bosch BAT612 18V Lithium-Ion 2.0Ah Clamshell High Capacity Battery

Using your Bosch BAT612 battery is a breeze. Simply insert it into any Bosch 18V Li - Ion tool and you're ready to go. The built - in fuel gauge lets you quickly see how much charge is left. In cold weather, don't worry, as it can still operate down to - 4°F. Just make sure the tool and battery are properly connected before use. When it comes to maintenance, keep the battery clean and dry. Avoid dropping it, although it can survive a 3 - meter fall. Store it in a cool, dry place when not in use. If you're not going to use the battery for a long time, it's a good idea to charge it to about 50% and then store it. This will help maintain its performance and longevity.
