I have *fantastic,* but unexpected, news. I am at my cabin where I can leave the battery charged for days at a time without worrying that the charger will be stolen. After two days of attempted desulfating with the Optima 1200 charger the battery is at 100% and is fully desulfated!!! This means...

SubLGT, Thank you for posting this. For me, this would not be worth the cost, particularly if the entire charging system would have to be modified in any way. AGMs, which do seem to be worth it, are approximately twice what a FLA battery are. These lithiums would be at *least* three times as...

You're not hijacking this discussion at all *if* lithium batteries can work interchangeably with AGMs in all automotive applications. I think SubLGT and I got much of our information on AGMs from Battery University--at least I know I did--and some of it appears to be inaccurate. If lithium...

Actually that's in the same price range as the Optima 1200 charger and it is almost *twice* as powerful. From their website, however, it looks as if you might have trouble finding one.

Has anyone seen the latest labeling for X2Power batteries sold at Batteries Plus Bulbs? I assume they will still honor the warranties on the NorthStar batteries they sold.

I like the Optima chargers, although it appears they may have been discontinued. They are still available all sorts of places. They were specifically designed by Johnson Controls for AGM batteries, so they do a better job than most.

Somehow your answer ended up in my spam folder. I did not know this. It seems that you and I get a lot of our information from the same source, Battery University. They are the ones who seem to love AGM batteries. If CCA measurements won't help, then I will have to start taking some of the...

SubLGT, One thing for certain, my little NOCO Genius PRO 25 doesn't product 500 amp pulses in its "Repair Mode!"

wrcsixeight, Once again, your long response knocks the ball out of the park. However, I think you are giving me less credit for trying to follow your advice than I deserve. I believe you suggested I try running the "Repair Mode" on my NOCO Genius PRO 25 charger a second time, which I did. I am...

SubLGT, The car I have in the garage, which I leave on an Optima 1200 all the time is a Group 35 X2Power/NorthStar. I previously used Clore Automotive Solar Pro-Logix chargers *until* I switched to the Optima 1200 which was designed specifically for AGM batteries. The Optima 1200 seems to be...

SubLGT. I'll have to investigate EFB more. I knew they existed but I did not know much about them. I have read extensively regarding AGMs because they are covered more widely. I also own many more of them. (I have sixteen of them at my off-grid cabin.) AGMs appeared to be exactly what I wanted...

wrcsixeight, Once again, much to think about! I did take your advice, and I have the battery back on the NOCO Genius PRO 25 4-hour Repair Mode. I'm assuming, because it is a smart charger, one can't run the Repair Mode too many times and harm the battery. As I said above, it is also clear that...

Pelican, I was not being clear. When the NOCO charger did it's charge cycle, it's 15-minute charge which brought the battery up to full, must *not* have been doing *any* desulfating because of how fast it occurred. Yes, the NOCO *does* have a separate "Repair Mode," which can take up to four...

SubLGT That is very interesting. I don't know that much about EFB batteries, although I was aware that they existed. Now everybody is going after the AGMs because they appear to be the current king-of-the-hill. My considerations were slow self-discharge, cold tolerance, and faster charging...

@wrcsixeight, Once again your long cogent explanation appears to be born out in my actual life experience with my actual experience with my NorthStar AGM in my truck which I leave outside. I bought AGMs for all of the reasons you mention above. They appeared to be both the ideal battery for my...

wrcsixeigh, Once again I have very much enjoyed your two long replies and I have spent hours trying to digest parts of them. I agree with SubLGT that you have more than enough excellent material for an eBook. You would be guaranteed at least two sales immediately. :) I'm still confused about...

@wrcsixeight, Once again, it takes me many hours only partially to digest your helpful response. I thought I alone had caught the "battery bug," but you appear to be afflicted as well. :-( I also need to clarify a few things. I *only* have the Optima 1200 and NOCO Genius PRO 25 as my *latest*...

wrcsixeight, I've spent many hours reading over your long and extremely helpful response. You've obviously learned more about batteries than I will know in a lifetime. I think I have been seduced largely by advertising, which is what led me to buy the Optima® Digital 1200 Battery Chargers and...

Thank you for this long, and I'm confident, very accurate, response. You obviously know far more about both batteries and electricity than do I. I think, from your response, I'm going to need more help in accurately diagnosing the problem because, although I have the equipment, I lack the brains...

I've used this Optima® Digital 1200 Battery Charger for a few years and it has always seemed to work well. I did run a 4-hour "Repair Cycle" on the battery with the NOCO® Genius® PRO 25 (I just bought this charger.) and it completed "successfully." I guess I am going to have to start monitoring...
