The lithium battery is a 3-volt, 550 mA-hr battery in a 2450 blister pack. It can
last up to 10 years before it must be replaced. However, its actual lifetime
depends on the number and duration of power outages that may occur. It has
enough capacity to last up to 5500 hours after power is lost.
Replace the battery when the LOW BAT LED lights. You can purchase
replacements in most computer and electronic retail stores. Ask for a type 2450
battery. Be sure to replace the battery with one made by the same manufacturer.
CAUTION: The battery may explode if it is replaced incorrectly. Replace the
battery only with the same or equivalent type as described above. Used lithium
batteries can be considered other household waste and disposed of accordingly.
Do not incinerate, disassemble, or deform batteries. Do not attempt to recharge
the battery. Do not heat the battery over 100˚ C.
Failure to follow these handling instructions may result in battery failure,
including seal breakdown, leakage, internal shorting, fire, and potential
explosion.

empfohlenen Typ. Verbrauchte Batterien sind nach den Angaben des
