Don, it will pevent them from overcharging, maybe. But it just cuts off at 14VDC max. So it allows a voltage that is TOO HIGH for float charging, and TOO LOW for proper bulk charging.
Sure, it beats nothing. But failing to charge batteries up to 100% is among the reasons that batteyr makers claim so many folks only get half the life they're supposed to be able to get from properly charged batteries.
If I only wanted to prevent my batteries from overcharging, I could use a 60c 3-pin regulator and two resistors to bump the set point and be done with it. The $1.79 for an Altoids tin to mount it all in would be the most expensive part.
Is that ebay cheapo better than nothing for Squidd? Sure. WTF, his battery is small enough and cheap enough that replacing it every two or three years probably is more economical than buying a proper solar controller to prolonge the battery life.
