It has arrived - an affordable Dual Purpose Lithium. Well known, tested brand - I use the 230ah in my RV.

Vs the Interstate batteries at $380 to $450! 800/925 CCA
37 pounds vs 48-72 pounds for the Lead Acid -
The more expensive G31 Interstate stores 100ah, 70% usable
And you save 60 pounds of weight (hmmm, I think that means an extra MPH!!!)

These are 140ah and 100% usable.
Per the Merc specs, they want a minimum of 800CCA. Seems to fit the bill.

I have read most newer charges can get these at least 80% charged, most say 90% plus without being a lithium specific charger.

Winning....now, where can I find all the quarters I need.......

 
I found this Mercury Outboard Bulletin, has anyone actually moved over to a lithium batter for the larger (250hp) mercury outboard?

I have tried to confirm this bulletin with Mercury, no luck yet but still working on it. I found this through RELion site.

A word of caution is VERY important here! NEVER use a charger for LI batteries that is not specifically designed/approved for that use! That includes those in various vehicles , boats and planes. Li battery chargers have safety circuits that chargers for other types of batteries don't have. Conversion of any device to LI batts must be accompanied by chargers that have the appropriate safety features.

Even Boeing had to learn that the hard way when they put LI batts in the B787 with out onboard AND ground power units that properly monitored all aspects of battery use. The high power density and propensity to ignite of LI batteries makes them inherently more hazardous. Use great care to not short-change any safety procedures.

The reccos by Mercury in the above attachment are a great start, but don't go far enough to really highlight the problems.
