Inverter AGM questions
I have been thinking about installing a inverter in my truck, either a 2000-3000 watt. I would use it to run small power tools, air compressor, an electric blanket when on the ferry system as you can'...

I try to be patient with customers but my tolerance vanishes when it comes to dealing with company "educated idiots" who are usually young, headstrong and utterly sloppy when it comes to researching data especially history and component integrity.
My longest history AGM battery has been measured on my mini platform scale. It resolves down to less than 1 gram, perhaps .3 grams.
In seven years it has not lost one measuring unit of weight.
AGM batteries are pressure sealed. People forget this. The batteries have a recombinant vapor to liquid recovery system built into the caps. They do not lose liquid ever ever ever, unless they are hideously overcharged. Not in the same universe of gradient overcharge as an open flooded battery. A flooded battery will lose 10x3 times the weight as an AGM battery over it's lifetime.
At high temperature, sulfuric acid eats lead. There is no way to stop it. Reduces voltage helps a lot but the majority of electrolysis is due to heat. Unless of course voltage is allowed to stray into 15.5 volt areas that no one is going to allow. Car computers will open loop and RVs will develop symptomatic negatives that virtually no one would ignore.
With influence of high temperature electrolysis the most influential counter action is to thicken the positive plate. I am convinced the Lifeline's double thick plate leads to near double the lifespan as far as electrolytic issues are concerned, How could they not? Does a Lifeline cost twice as much as competitive batteries? I have no idea because I have not the slightest interest in comparative shopping. Logistics wise I am crippled by being well outside the marketing area.
Thicker plates do zero to reduce the effects of abuse upon an AGM. Continual partial recharging, recharging a deeply depleted AGM with less then 20% of the rated 20 amp hour specification current. Having a 400 amp hour bank means an eighty ampere minimum charger. Wanna take a guess how many AGM 400 amp hour banks are recharged at lesser values?
So my take is unless an owner takes the time to understand AGM quirks and then rectifies his charging and management perhaps his best value choice would be chew & spit Chinese batteries.
