We use mostly SunExtender and have had the same issue. As far as I know, they are the same battery with different labels. I have had some success in being a LOT more aggressive with voltages & times and sometimes going above FLA settings to get banks to recover and perform closer to spec. Makes me nervous though, since more than 50% of a customer\u2019s investment can just vaporize with what one thought was appropriate charge settings. I suggest EQ as the new norm for AGMs, especially in grid-tied-battery-backup cases and where off-grid use does not give adequate absorb time.<div class=""><br class=""></div><div class=""><div class=""><br class=""></div><div class=""><div class="">

We have at least a dozen systems that failed early from lost capacity over the last 2 years with 2-4 year old battery banks. The AGM failures are all Lifeline battery made by Concorde.
Lifeline and my distributor both told me I was \u201cthe only one\u201d with failures. I dropped Lifeline battery after being a dealer for 16 years and many hundreds of systems installed. Historically we had seen 7-10 years average life from battery banks that we installed. One regular customer is at 12 years and still going. I have a sense of vindication now hearing from others about Concorde capacity issues.
Thank you,
Larry Crutcher

A Concorde AGM PVX 3050T recently failed in a bank of 8. Larry mentioned a couple of brands experiencing problems. These batteries are 4 years old and have been kept in float in an off grid system, never stressed. Hopefully Concorde batteries are not going the way of Trojan L-16s. Has anyone else had problems with Concorde?
