Hasselblad H Series Camera Batteries

[maxs]

What is the best way to maintain Hasselblad H Series Camera Li-ion batteries? Should they be charged up all the time even if partially depleted? Or should they be drained totally? What if they are not being used for longer periods?

Thx

1.
Avoid frequent full discharges (e.g. by leaving the
camera with the “Replace battery” warning on the
grip LCD for a long time). As Li-ion batteries have no
memory effect, frequent recharges are no problem. i.e.
recharging a battery that is not fully discharged will not
cause problems.

2.
The battery should be charged in an ambient temperature
of 10° to 45°C (50° to 113°F)
3.
The initial charge should be 12 hours in duration.

4.
If the camera is left unused for some time, the battery
should be removed since the idle current requirement
in the camera will drain the battery.

5.
The battery has a “fuel gauge” function that keeps
track of the charge level in the battery. As with most
Li-ion batteries this function should be calibrated a
few times a year depending on how much it is used.
Leave the camera on or use it until the grip LCD
shows “Replace battery” warning. Then apply a 12
hour charge. This will improve the accuracy of the fuel
gauge function which is used in the camera to indicate
battery status and to set warning levels.

6.
 If the battery is not used for a long time it is best to
store it in room temperature and charged to approximately
30 to 40% of the maximum capacity. To reach
this level, charge the battery full and then use it until
the camera status screen indicates 30 to 40%

You can re-set the battery "fuel gauge by a button combination, I am not sure if this combination is universal across models, others have broader experience and will no doubt confirm.
