Lead free solder is fine. When RoHS was first implemented, a lot of manufacturers had trouble changing their processes for the new solder. The result was a plague of bad, broken solder joints.
Nowadays, lead free solder is accounted for starting in the design stage. Manufacturers have had 15+ years of experience with leadfree solder and have largely worked out the issues.
Lead-acid batteries are extensively recycled. Electronics are usually just dumped in the trash, making the lead issue much more important.
