Battery Life
• The battery life depends mainly upon two factors:
• The intensity setting. The higher the intensity, the shorter the battery life.
• The age of the battery: Brand new batteries can be recharged hundreds of
times, but each time they lose a small amount of capacity. As soon as your
batteries start to bulge out a bit from the sides or do not last as long as they
once did, it’s time to start thinking about ordering a new set of batteries.
• You can expect the following battery life (roughly):
• Very high intensity settings (11 – 15): the battery will last only 1 to 3 hours
• Medium intensity settings (8 – 10): the battery may last 4 to 6 hours
• Low intensity settings (below 8): the battery may last 6 to 8 hours
• Recharge the batteries as soon as they are drained to get the best
battery performance.
