Sorry but I'm not sure. I haven't even thought about solar batteries all I can say is that I used to on my old recharger. They should have a code on the side which you you can check against the instruction leaflet. Sorry I couldn't help more
All I know is that it charges NiMH type batteries. If the batteries are solar rechargeable, then surely they are recharged via a small panel in the device that is needing to be recharged. But if they are as aforementioned and are NiMh type, I cannot see why not. But don't sue me if I'm wrong. LOL. Manufacturers website may tell you. Or write/phone/email them.
