Oh Tim 57 pages ! Give me the cliff notes version.

 

See my previous post

 

get a booster to keep it at full SOC

 

AGM batteries tend to have a higher specific gravity which requires higher charging voltage to maintain full charge but the companies manufacturing them know the application and generally will try to build to match most vehicles. The Diehard Platinums used to be made by Odyssey (owned by Enersys who also owns Northstar) but the lower AGMs were made by Deka/East Penn.

If you check out the User's Guides for each you'll find it depends on the intended application. For example Northstar which is designed/intended for automotive starting says 14.1-14.7V is the charging range. Odyssey which lean a bit more towards deep cycle say you need three step charging with an absorption between 14.5-15.1 for best deep cycle performance, but most of us are not doing deep discharges with our batteries. We are doing shallow cycles (engine starting) so the recommendation is kind of irrelevant.

I'm running AGM and have for years in all my vehicles without using a voltage booster however I will hit them with a bench charger about every 6 months.

Btw if you ever have battery questions... I'm happy to give my input ☺️

 

peeling off bed decals is a P.I.T.A. dunno why I thought this was a good idea.

 

get one of the 3M rubber eraser wheels. Makes easy work of it.

 

60 seconds of this and it wiped away like water. scary good stuff!

 

Good morning fellow Pennsyltuckyvanians!!!

 

GM all day 7 of vacation and getting bored. Lol. Up early planning a busy day, taking advantage of the warm weather. Hope yinz have a great day.

 

thanks buddy

 

On the side of my fridge….Yinz…wife even has us saying it now
Have a great one all

 

Last of 4 day shifts before a week off, then 5 night shifts annnnnd that’s the end of my full time job. Not gonna lie, half tempted to just quit today at 17:30.

 

Good morning PA. Monthly chiropractic appointment this morning.

 

The "Rack" ?

 

No, that's old school. I do lay on a table while corrects the spine, but it is vertical.

 

Morning all. Hope you have a great & safe day.

 

Hi Larry

 

Morning Pa.

 

I believe it, truck driving hard on the back.....
