Recharging Batteries
You may charge batteries while they are in either the Heartstream XL or the
optional M4747A Battery Charger Kit.
If the battery is being charged while in the defibrillator/monitor (with the
Heartstream XL powered off) a discharged battery will typically be
90% charged after 3 hours (at 25
o
C), as indicated by the Batt Charge LED on
the front panel turning from amber to green. After the LED turns green, the
battery will typically be fully recharged after an additional 12 hours at (25
o
C).
&$87,21 The battery should be fully charged whenever possible. Repeated charges to
just the 90% level will degrade the battery, reducing its life and capacity.
Refer to the charging procedures provided in the operating instructions for the
Battery Charger Kit.
