One of 6 bad battery?

Yahoo Message Number: 111891

Hey-

I checked my 6, 6v domestic batteries today with one of the turkey baster testers -

One battery I think is going bad - the other 5 are all reading 1275-1300 on all cells pretty evenly, but the one battery varies from 1260 to 1300, and one cell was unusually high in acid level. I do check and fill the batteries as necessary every 3 months, and I did fill them 2 weeks ago. How is the one cell much higher now?

The bank is float charged, and I did a equalization cycle about 2 weeks ago (last time as about a year ago).

So, my question is, if the one battery is going bad, will it negatively effect the other 5, such that I should replace the one battery?

The batteries are Interstate Deep Cycle Extreme- GC2-XHD-UTL - I think they are around 4-5 years old at this point (the date stickers were not changed to show the date).

Thanks,

Yes a Congleton cell in a single battery will effect the entire bank it is part of.

Hi Wes, My Dec. 2012 T105's are routinely 1.260 to 1.275 and still float easily. One battery will effect the performance of the bank but .040 isn't alarming.
