Car has been working great. The other day after five miles the charge gauge started flashing then went to turtle mode and a red bar appeared. I was able to get back home. Now when I plug in the charger it charges for a few minutes and goes to green fully charged but the gauge is only up to two green bars. The batteries are 12v AGM mfg. 5-18. thanks in advance for any help. Stan Riva. 2005 E4 ---

Not enough information to be of much help. @Old_Houseboater tells us that agm will only last about a year if on the wrong profile. He can correct me if wrong. ps. I see now 2005 Turn off main switch. Plug in charger. After boot-up light sequence, leds will blink a profile sequence. Such as 1-3, 1-3 for #13 ---

Sounds like you have a bad battery/s. AGM batteries need to use AGM setting if available. If not should be set to flooded setting #13 on Delta Q charger. Batteries could also be bad and charger is shutting off on (overtime) before batteries are fully charged. Disconnect the red wire coming from the charger to the battery, Plug the charger in and count the blinks. should b 1 blink pause 3 blinks (13) In a message dated 1/5/2020 10:26:38 AM Eastern Standard Time, [electricforum@discoursemail.com](mailto:electricforum@discoursemail.com) writes: ---

If you are interested in low maintenance and better performance check with Dave @Inwo and do a lithium conversion.
