<div>Must have been and bought from a Home Depot instead of a True Value, hehe. I have had great luck with them. Hopefully this all helps.</div>

Deep cycle AGM's are a different<BR>beast. AGM are more susceptible to being damaged by<BR>overcharging. Also most sophisticated battery chargers go<BR>through three distinct phases depending on the initial<BR>SOC. With a car alternator, you are not going to get this<BR>this unless you go through a PLC and program in the charging<BR>curves.<BR><BR>I have had<BR>good luck over the last 8 years with on onboard battery<BR>charger for AGMs that is used for electric car/truck<BR>conversions. When my boat's main propulsion bank was<BR>120 VDC I used a Zivan NG3 120-18 and now that I have<BR>switched to 36 VDC bank, I use a Zivan NG3 <A href="http://www.zivanusa.com/pdf/NG3.pdf. ">http://www.zivanusa.com/pdf/NG3.pdf. </A><BR>I have had hundreds of recharges using these rechargers with<BR>no problems. You can get a panel mounted remote<BR>display that shows were you are on the recharge. The<BR>suppliers adjust these to match type and capacity of your<BR>AGM batteries. They are a bit pricey but often come up<BR>eBay. I really like being able to plug my boat into an AC<BR>receptacle and come back the next day with them fully<BR>charged having gone through a charging curve that is tuned<BR>to my AGM batteries. For winter storage, you can leave the<BR>boat plugged in indefinitely and the system supplies a float<BR>charge again tuned to your AGM batteries. The only<BR>negative on this system is that a battery bank is typical<BR>made of individual batteries wired in parallel and series. <BR>This system does not have a Battery Management System (BMS)<BR>like you would have on a lithium-ion battery that<BR>controls charge on individual batteries, just he overall<BR>bank. I have had to replace individual batteries that<BR>degraded over time. <BR>Cliff <BR><BR><BR><BR><BR>From: hank pronk via<BR>Personal_Submersibles<BR><<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>><BR><BR>To: Personal<BR>Submersibles General Discussion<BR><<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> <BR>Sent: Monday, May 18,<BR>2015 6:11 PM<BR>Subject: Re:<BR>[PSUBS-MAILIST] agm charger<BR><BR><BR><BR>Scott,<BR>I have<BR>been using the same thing and they don't last, we pay 85<BR>dollars here.<BR>I added a couple pictures that<BR>show the ballast tanks nicely, I am sure happy with it.<BR>Hank<BR>--------------------------------------------<BR>On Mon, 5/18/15, <a href="mailto:swaters@waters-ks.com">swaters@waters-ks.com</a><BR>via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>><BR>wrote:<BR><BR>Subject: Re:<BR>[PSUBS-MAILIST] agm charger<BR>To:<BR>"Personal Submersibles General Discussion" <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>><BR>Received: Monday, May 18, 2015, 7:05 PM<BR><BR>Hank,I<BR><BR>charge my AGM's with a computerized battery charger.<BR>They cost about $65.00 at True Value Hardware.<BR>They charge<BR>at the correct rate and shut<BR>off when the charging is<BR><BR><A href="http://complete.thanks/">complete.Thanks</A>,Scott<BR>Waters<BR><BR>Sent<BR>from<BR>my U.S. Cellular® Smartphone<BR><BR>-------- Original message --------<BR>From: hank pronk via Personal_Submersibles<BR><<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>><BR><BR>Date:05/18/2015 5:58 PM (GMT-06:00)<BR><BR>To: <a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a><BR><BR>Cc: <BR>Subject:<BR>[PSUBS-MAILIST] agm charger <BR><BR>Hi all,<BR>I am tired of buying<BR>battery chargers for Gamma.
