Battery power - different mAh specs?
« on: July 22, 2016, 08:38:06 AM »

I noticed that over the years Hasselblad batteries have moved from :

1.850 mAh on the H4
2,900 mAh on H5
3,200 mAh on the H6

all have 7.2 VDC.

Does it mean they can be used on all the models?

What does mAh mean?

Milliampere hours, it's how much energy it can deliver per time, so the bigger the number the longer the batteries last. They should be compatible, unless they have internal logic and the software doesn't recognize them (like Nikon bodies that used to not turn on with third party batteries).

The H6 battery has almost twice the capacity of the H4!

Thanks.

So it would make sense to keep them as spares. You never know you need some extra shots.

And since it is the same 7.2 V, I can still use the old chargers. Correct?

Yes, the chargers should work.

As for keeping them as spares you should test them first and see if they are recognized or the camera works with them. They should, but it's best to ask to a Hasselblad rep or your reference store.

Battery technology gets better over time.
mAh is milliampere hour. The number of milliamps (current) delivered times the number of hours delivered.

That seems logical, but might not always be correct. It depends on the battery chemistry. It can be as simple as a firmware update to the battery charger.  This was the case with Sony NP1 video camera batteries several years ago and with Anton Bauer batteries somewhat more recently.

OK, guys. I understand enough. I am going to try to sell them.

Better to have 2 new puppies then 3 old dogs.

Definitely, batteries wear out over time and usually have a limited number of charge/discharge cycles, so they lose capacity and reporting accuracy overtime anyway.
