Hi.

Just measured one of mine: 5" x 3.5" x 1.5"

As fer yer battery question, I do not know (I've run only the Costco batteries, lol) - perhaps drop either batterychrgers.com or Schumacher an email to be safe.

good luck!

Will do, and thank you for the dimensions..

Btw: can't believe I stumped ya

Thanks

 

Well I emailed Schumacher.. This was there reply:

"I would technically recommend the SEM-1562A charger. This unit has a maximum charging voltage of 14.7v which is optimal for those types of batteries".

Guess its not good for glass mat batteries..

 

I will be using this style of connector. Bulkhead male under the front bumper, straight to the starter & Ground. Then I can charge, boost, whatever.
