MBD-10 battery maths
Mar 11, 2011

I have a D700 and I am looking at getting an MBD-10 for portrait sports shots (70-200VR2). But I want 8fps too occasionally - just because. In the UK it costs a fortune to get the MBD10, BL3, ENEL4 and charger set. Seems like a total rip off especially the charger. There are a lot of threads talking about using 8xAAs instead. Sounds a whole lot cheaper for occasional 8fps usage.

It seems that all types of batteries can meet or beat 2000mAh, and 8fps depends of battery voltage: ie ENEL4=11v vs ENEL3=9v. So by that logic I can see that 8xAA Alkaline works: 8x1.5=12v. But they are single use.

I also infer from threads that 8fps is also achievable using NiMH rechargeable AA batteries. It seems like the answer to my quest for affordable 8fps. But these produce 1.2v which means 8 produce only 9.6v. That confuses me. Is 9.6v really enough to fire at 8fps? And follow up question - does it last for bulk of battery life, or does fps drop off quickly during usage? Thanks in advance for any good advice on this.

cheers A
