Obviously the 925 is much better for starting but wondering if anyone has experience using the 680 for starting? I've been using one on a 4 cyl Lycoming with no problem but wondering about the 6 cyl? I just did some testing on a Chevy van 6 cyl I have that needed a new battery, I have an older 10 year old 680 battery I had on the bench for shop projects I decided to try. It does start my van in the winter cold but marginally because although it will turn over the engine adequately the clock will also reset to 12 o'clock sometimes, so I know this is marginal but may be attributed to the 10 year plus life. So I ordered a 925 from amazon got a great deal, free freight and put in in my van to check it. What a noticeable cranking difference--with authority! Recently with this cold snap in Mi had a minus 27 deg morning and there was no hesitation with the 925 starting the van. Sold on the 925 as very capable, but interested in the weight savings and I may have to get another new 680 to do the same test but thought I'd check others' experience with the 680 for starting. Anyone with experience? -------- Dave Ford RV6 for sale RV10 building Cadillac, MI Read this topic online here: http://forums.matronics.com/viewtopic.php?p=438635#438635 ________________________________ Message 2 _____________________________________ Time: 11:29:46 PM PST US From: Phillip Perry Subject: Re: RV10-List: PC680 vs PC925 There are folks running both successfully. My system is dual batt with dual alts and have a 680 on both. However I have a contractor that will allow me to bind them together in parallel if needed. With that setup I can get redundancy, 1360 for cold starting if required, and a backup starting battery in the event I show up to the hangar and have a dead primary battery. My first engine start hasn't occurred yet, but I'm not worried about the 680 doing it based on other people's success with it in the -10. I only point this out in case you happen to be running a dual-dual system. If I were single battery though and in a cold climate I'd have a hard time turning my back on the 925 with all the lifting power the -10 provides.
