We use a LOT of Optima batteries on the far. We can start a LARGE diesel engine from one made to fit a car. Easily. They outlast every other battery (other than the ones 4 or 5x more expensive and designed for tractors etc.) we've ever used.
You'll pay out the nose for them, but that's what I usually put in my important rigs these days. I think I've only replaced one of them in the last 4 or 5 years (this includes ones in tractors etc.) No idea on the charge controller. If it were me I'd probably just hook up a good electronic battery charger and be done with it. laters, marlon ----- Original Message ----- From: "Jerry Richardson" <[email protected]> To: "Motorola Canopy User Group" <[email protected]>; "WISPA General List" <[email protected]> Sent: Sunday, August 02, 2009 12:47 PM Subject: [WISPA] AGM Batteries / charge controller > Recommendations on AGM batteries for temp range 0-90F?
