Can a slightly low battery cause no spark?

[philtheskipper]

I've been having problems with no spark on my Suzuki outboard. The other day I charged my batteries on a long trickle charge and it then fired right up. So, I went out on the lake and it ran great. My voltage meter showed it was charging good(both batteries). I got to my fishing spot and shut it off, then switched to just one battery. When I went to start it with both batteries it wouldn't start. Seemed like it was cranking as usual but after awhile it did start to slow a little. Do you think I just have a bad battery or something? The way it was cranking seemed like it had enough juice. Do these electronic ignition systems need 100% power to get a spark?
