carbon foam batteries in Canada

GordonThree,

Another advantage of carbon-lead batteries is not having to get to 100% state of charge on every cycle. Of course, that is still desirable.

Not laying in the snow to check the electrolyte levels. I don't miss the flooded jars one little bit.

I've never checked the electrolyte in my Deka batteries. They're six years old now, sealed AGM. I suppose they could lose electrolyte if abused or a re-capture valve fails but...

$200 for 1300 cycles or $800+ for 5200 cycles? What is the advantage?

I think like that too ... now.

However, I didn't think like that 15 years ago - and that's when we bought a used car with around 38K miles on it at the time. We still have that car and it has over 195,000 miles on it.

It's transmission completely failed 5 months ago. The shop installed a new (or remanufactured) transmission in it for FREE. The charge for the transmission and labor would normally have been over $3600.

We received a great Christmas present from our repair shop! Was it based on a lifetime warranty ... who knows?

Phil,

5200 cycles to 50% =~14 years..... That would make me 86.

Well, Don ... for our part-time camping style ... around 1300 cycles at an average of 50% DOD for the DC series is plenty good enough for us (see the lower left graph of the four graphs on page 2 of 2) ;) : https://resources.fullriverbattery.com/fullriver-battery/external-media/brochures/dc-series.pdf

P.S. The graph I reference in the above link is better cycle life than the Li battery in my $850 smartphone :( !!

****, those are expensive
