2900Mah battery

[raffa]

Hi everybody.
long time lurker but I'm evaluating some used H4D to buy in the next month or so.
a quick question: is it possible to use the new 2900Mah battery grip on a H4D-50 or -40?

[jerome_m]

Yes. It is supported on recent firmware.

[Dustbak]

It is and after it has been used for a while it lasts much longer than the original battery.

The same experience here. Highly recommended. But as jerome_m already pointed out, the latest firmware update is a must.

Will the BC-H 7.2 charger charge the 2900Mah batteries?

[raffa]

thanks for the answers.
could you give me an idea about the average number of shots achievable with the new 2900 battery, compared to the old one?

Will the BC-H 7.2 charger charge the 2900Mah batteries?

Yes, it does. But it takes 5 to 6 hours to recharge a fully depleted battery.
