Replying to Boot Heater Question, HOTRONIC

Hey guys,

I'm running an old pair of hotronic power 3.5+ batteries on my boot heaters and my BLUE plug chargers got fucked up last season and I haven't been able to find a new charger. I'm up in Apex, BC where it's cold as balls and my batteries just died.

I'm wondering if I used the WHITE plug chargers from the newer hotronic batteries if that's all I have available and what (if any) the chances are of my batteries exploding or just completely failing on me altogether.

Any info would help, cause my feet are seriously cold.
