        yes, battery can be serviced. but there will be a few test needs to be done. which is determining the state of charge and load check for each cell without 0.050 difference on the hydrometer. if the state charge and load check fail, the battery is scrap. WARNING i dont suggest to serviced your battery, because it could result to thermal runway and worst explosion

          Thanks everyone for your feedback and comments. The battery wasn’t taking a charge at all… it was still powering stuff but it was slowly choking and struggled on start ups. I will monitor the charge of this new battery to make sure the alternator is charging this new one.

          The last thing I need is a bad alternator.

            The best chance you have is to pull the battery and let it sit on a slow charger for a good long time. At least overnight. You might save it for awhile, but it’s going to fail sooner than later probably, and your friend might be stuck in a parking lot in the rain.

              Lead acid batteries require a sulfuric acid solution, usually 35% sulfuric acid 65% distilled water. This is part of their chemistry to operate as a battery. Usually the water will boil off allowing distilled water to be added. If it doesn’t take a charge, then it is worn and needs to be replaced.

                  Make sure that the alternator is regulating the charge properly. Over charging will kill a battery. Not sure if regulator is internal in alternator or external on your vehicle. I use dehumidified water from my dehumidifier in my batteries and radiator and save it in gallon jugs to reuse in the winter to humidify the house. Humid here in summer so I get enough for the entire winter. No chemicals like in tap water.

                    That is a great suggestion, I never thought of that and I get gallons of water from my dehumidifer per week.

                      The battery being low on water will hurt the plates inside.
                      then when you do add steam distilled water the damage
                      has been done. have the battery load tested at an auto store.
                      But I believe its time for a new battery. get a maintenance free
                      battery. no caps to add water + less gasing off. A dehumidifier
                      does not remove impurities from water. all a dehumidifier does
                      is remove moister from the air. For proper battery water the label
                      must say steam distilled. Don’t be fooled if the the label says distilled.
                      that could mean filtered.

                        That’s an interesting tip to use a dehumidifier as a source of “distilled” water. I normally just buy distilled water at Walmart, where it is really cheap and pure. I know some people use de-ionized water, which (in my opinion) might not be quite as good.

                        My dehumidifier has a dirty capture container, and I do wonder about the possibility of mold growing in the distillate flask, which wouldn’t be so great in a battery. The cool thing about distillation is that the process of boiling should be sterilizing as well.

                          Today I spent a few minutes reviewing the way dehumidifiers work (Wikipedia). Evidently there is evidence that aluminum, copper, and zinc ions are still present in the fluid, not to mention the chance that fungal spores may be present as well. Although the condensate that results from the process of cooling room-temperature air is theoretically pure, contamination at the collection site is the main issue. Guess I’ll still be going to Walmart, ha ha.

                            Some excellent posts but as a former flat rate tech replace the battery, if it shows itself to be low especially with a conductance tester replace it. The days of ‘servicing’ batteries are gone in my opinion as they seem to be engineered down to the electron these days and if they start to fail it’s not likely they will come back.

                              +1 to this statement

                                Awesome, I wanted to see if there was anything I could do to save the battery. I was able to get a new one so far so good.
                                Thanks everyone.
