Accumulator

Hello everyone in this forum, I have a problem with the accumulator of my civic suddenly it became heavy at the start, terminals, terminals and all well except when trying with a hydrometer the battery in the 6 cells contained in the accumulator a bad frame "downloaded" the battery does not have much time to buy it can have repair? For your attention thank you very much

Hello friend, if the battery is wrong in a cell means that this cell is short, I advise you to change it, there are those who repair them but the result is never good, greetings.

I also imagine that the repair is not very sure I will have to replace it thanks for the advice ...
