Re: Battery health during Coronavirus time

Everything I've ever read suggests that 70% is way too low for a starter battery. Deep cycle OK, starter not so much.

I guess it depends on your notion of what a "reasonable" life is.

I agree...above 80% for lead acid is a common theme out there.

80% SOC is considered the point below which damage will occur from a single discharge. Not a huge amount for, say, 75%, but damage nonetheless. Storage/rest charge for a lead-acid battery should be as near to 100% as possible. By keeping the starting type OEM battery in a Leaf below 80%, the car is apparently programmed to damage the battery. This isn't Rocket Science, and it wouldn't be any more expensive to program the charging system to keep them topped off to 95%, so this is yet another case of "INS" or Inexplicable Nissan Stupidly.

PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

Agree. Hard to understand. Their other cars all maintain the battery appropriately, presumably.
What were they thinking? It's odd.

I've entertained a battery tender for the Leaf, but am putting that off for now. I may eventually pick up a solar one at some point, but I'm not sure how long we'll keep the car. Depends on my wife's recovery.

Not going to do anything.
Appears that the battery algorithm will take care of things.
I will probably take it out once per week also
good idea...joy ride is needed sometimes :D
At least to keep the tires round. :)
I noticed you're still working with polymers.

You know that you are perfectly safe passing the time by just driving the hell out of the car all day long...

It is not like we much be secluded to our rooms...
