All I can add is I've not looked up any manufacturers specs recently, however, when I was in an industry that used 100,000's of 12v deep cycle batteries we were advised to discharge batteries to 0% and re charge prior to putting them to sleep for winter storage. The golf car industry routinely discharges and re-charges these batteries yearly and despite daily use drawing batteries well below 50% levels they come back and last 4-5 years, in most cases. My group of employees and distributors routinely maintained over 80,000 batteries yearly.

I called one of my former technicians and the industry is still doing this today. We started putting in the AGM product as an option and I'm not sure what they are doing with these, but Trojan and Interstate both got the discharge and re-charge program yearly.

Thanks. Now I need to research SOC meters. Do others find this a useful device?

In my trailer it shows level of charge by the color indicator on the monitor. I'm assuming this is not a very accurate indicator. Is that correct?

Just buy a simple cigarette lighter plug in volt meter. Leave it plugged in all the time to see your soc at a glance. This is not rocket science. After a while youll instinctually know just where you are!

I ordered one of these meters that plugs into the cigarette lighter from Amazon. I took about four weeks to get it but it works great.

Thanks for the recommendations.

Should I let the batteries set for a while then put it boost mode?

Thanks Dave

It takes my pd4655 a couple of days (at least)before it goes to float mode. I have 260 AH of lifeline AGMs
