I could have run 20 Km marathons daily, become Vegan right out of the womb, and purchased a hundred dollars worth of vitamins and supplements monthly, all for the objective of gaining lifespan.
For me. My lifestyle?
Hahahahahahahahahahahahahahahahaha...
Shirley you jest. I would have been a sure target for some malfunctioning transit bus.
A manufacturer CAN NOT RECOMMEND constant voltage saturated charging because CHARGERS CANNOT DO It.
As fuel prices rise, my wallet tightens in response. The best way to preserve a battery is to pour a ton of money into it's maintenance and get tinnitus from hundreds, nay thousands of hours of excessive generator run time.
There is a CURVE exhibiting lifespan versus charge amperage limits. It is most pronounced between 10% of amp hour capacity and saturated charging. Under lab conditions it is something like + - 10%
This is for a ten % min and perhaps 45 ampere max charge span.
Factor in generator annoyance -- generator wearout, fuel, and logistics costs then try and defend so-called "ideal max charge rates"
"Uh raised muh oan tomatoes. Can you taste the difrunace? Doan wanna talk about the cost -- pretty touchy abut that"
I tend to think more about amp hour consumption versus recharging costs to replenish. You know -- a hundred dollar battery versus five hundred dollars to recharge. In deep double-canopy shade.
My car engine would last longest if driven at exactly that speed where the transmission switched to overdrive -- 42 mph. But then if I can listen to a generator hammer 3 extra hours every recharge -- I can leave the car parked and use a unicycle (less footprint).
