Replacement battery for M243 cordless vacuum cleaner, 22.2 V
Use your vacuum regularly to keep the battery active and prevent complete discharge. If you do not use the vacuum cleaner for a long time, e.g. on holiday, store it with a partially charged battery (approx. 50-70%).
Store the vacuum cleaner and battery in a cool, dry place. High temperatures can affect the performance of the battery and shorten its life. Do not store the vacuum cleaner in direct sunlight or near heat sources.
