New capacity rates for old batteries?
I was talking to someone in the tech dept at NAWS last week on a different subject and out of curiosity asked about pricing on another set of Crown 6v 395 amp/hr L-16 batteries. I purchased 8 last August (local solar guy ordered from the factory, great price) and was considering doubling my battery bank so I needed matching batteries.
He kept suggesting the Crown 440 amp/hr size and when I reminded him I need to match what I already had (395 amp/hr) he said they were the same battery. Due to changes in industry standards on how to measure amp capacity most battery manufacturers were increasing their rated amp capacities.
Anybody else noticed that battery ratings may have climbed??? Either way I'm leaving my battery size rating at 395 amp on the Conext battery monitor although I've noticed that the battery voltage after a cloudy day indicated more energy remaining in the battery than the Conext SOC meter does.
I have not used specific gravity to check the meter vs voltage readings yet to see which one is more accurate about remaining power in the batteries.
