Note — The battery capacity of re-chargeable batteries degrades over time
and number of recharge cycles. Toward the end of its useful life, the battery
capacity may be reduced by 30%. If this reduced battery life is unacceptable
based on your use model, Philips recommends replacing the rechargeable
battery sooner.
