12 Volt flooded battery question

[Scott_DeWaun]

I took hydrometer readings in all 6 cells of my RV battery. Results:
Cell 1: Gage reads in between 1.275 and 1.300 specific gravity; ("Good Condition") on the hydrometer scale.
Cell 2: Gage reads in between 1.100 and 1.150 specific gravity; ("Recharge") on the hydrometer scale.
Cell 3: Same as Cell 1.
Cell 4: Same as Cell 1.
Cell 5: Same as Cell 1.
Cell 6: Same as Cell 1

The RV is plugged into 30 amp shore power. The battery is therefore under controlled charge. There has been no change in the readings for Cell 2 in 48 hours. Fluid levels are satisfactory.

Question: If one cell is bad and will not accept / hold a charge should I replace the battery?
Thank you in advance.

YEP, 1 dead cell and the battery is junk.

Thanks for the input Bob. I'll invest in a new battery and try to remember to check the cells on a better schedule than this first one. Would love to see a picture of the '58 Belair!
