My opinion is Niner's info is valuable and should be copied and stored by folks who have telecom batteries.
I just don't get the complaints fostered by some that bleat "I don't wanna deal with this stuff". Then they are the first to bitterly complain that their batteries puked and blew snot early on.
Wanna know how much time I spend "nurse maiding" my Lifeline? Oh two or three seconds a day on average. Most days nothing but glance at voltage. When it's time I tweak down the voltage, or increase it - ten seconds maybe.
24 (12 in parallel) 2-volt cells requires perhaps 20 minutes every other week to maintain. Pop all the cell caps and dip one after another. Note results, then pop the cell caps back on.
I time generator charging time according to the degree of discharge. The chargers are set to 29.8 volts. I twist an Intermatic 4-hour timer to what I believe will fill the batteries. The timer fires a contactor which in turn operates a contactor. The contactor feeds 3 chargers.
When the generator unloads I can hear it. Time to walk up the path and by the time I get there the turbo has cooled down. The Trace 4024 maintains float of @ 26.8 when on shore power.
It's a tough life all this. I resent being handed a mere 23 hours and some off free minutes every few days of a continuous power outage.
I would not hover on, near, around, or withing 50 yards of a battery charger. I have better things to do. Like wondering when my automatic dishwasher will show her smiling face.
But my idea of pain.in.the.ass happens tomorrow. Needing 166 miles of driving to get the front end aligned.
However watery franken-beer, cheetos and The Charlotte 500 are similarly low on my list of priorities. It would mean the Finding of The Lost Remote which infuriates my sensibility. If I want a real handful, I have four rambunctious granddaughters that occupies my spare time.
But, battery maintenance is a pip on the loss of free time radar screen.
