Just took a look and it may be in series if looking at the way the battery placement is (facing in opposite direction) so I assume they output 4.5volt. One day, I am going to pick up a really cheap voltmeter although I say this to myself every time I customize some wiring. Wonder if they have that sort of thing at Harbor Freight?
