What should I put back in my 8D's and where do I go about getting it, provided you don't tell me tap water? | ||

never tap water.... If you are the same guy that was fixing a crack...look in your phone book ,under ..BATTERIES..call different places till you find one that will fill it with acid.... If you are adding to a good battery that's a little low...you can add distilled water...available at any grocery store | ||

Not the same guy 2D but I'll find some acid tomorrow. Can I buy it or will I have to take those monsters out and have 'em filled? | ||

got a Napa auto parts store near you think I bought a 2.6 gallon for around 6 bucks but that was a couple years ago I even seen it at home depot but they were higher at Napa they sell it in various size containers | ||

I would take the batteries to them...how many gallons would you buy?...how many trips would it take till you got 'em full ??...but...everybody does things different...you make YOUR decision... | ||

and if your going to do it someone on this board at least i think it was here they say to turn the battery over and let the old stuff drain compelty out and go in with new stuff and you could get a couple more years out of then just a thought. i know i did it with golf cart batteries and work for me . the batteries i found in the trash put new stuff in them charged them up and that was 3 years ago but it your call | ||

I agre...think after a few years,new acid in those expencive 8D's is a good investment | ||

Hi Nick, What I have done in the past is this. 1. Take the batteries out of service. 2. Take them somewhere so you can safely discard your old electrolyte. 3. Use a water hose (gentle pressure) and rinse out each cell. 4. GO to NAPA and tell them the size battery you'll be filling. Or better yet, take them with you and have them do it. NOTE: You shouldn't fill them completly with acid. There needs to a mixture of acid and distilled water. Glenn | ||

I disagree with Glenn,...it's a battery, not a radiator, and doesn't require diluting. Commercially available battery acid already has a water percentage blended by the manufacturer to provide the proper PH level/specific gravity when poured over clean lead plates. We add distilled water to replace that which is evaporated/boiled off during normal use. See Gould Battery Co.'s web site for more info. ...JJ | ||

JayJay, I'm sorry if I confused anyone. I should have made a note stating that I used pure acid. The NAPA store I used had both pure acid and diluted electrolyte (there is a big difference). As far as it being a battery and not a radiator...you're correct. But flushing the water through the cells will clean the plates; and that can make a big difference later on. Again, I'm sorry if I misled anyone, but I know that it give my batteries an extra 2 1/2 years. Glenn | ||

Depending on the age of the battery, it's state of charge when emptied and how it was maintained, the plates will have a variable amount of sulfation. Batteries operate on a principle of a chemical "tug-o-war". Adding new acid to a sulfated battery is basically equivalent to adding too concentrated acid to a new battery. The chemical balance establishing the "rules" or competitive advantage in the tug-o-war will be upset. Check your batts with a hydrometer after filling and frequently during a equalizing charge. Remove electrolyte and add water as necessary to keep the batts within the proper specific gravity - if you can. I feel that this is just a stop gap measure and might be all right to "get you home" or in a single batt situation but for a batt bank, like a house bank, you're asking for problems and risking killing the other batts. If you feel your time is worth more than $2.00/hr, you might be better off with a new batt. (little exaggeration there, but you know where I'm coming from) YMMV, | ||

Well, I think you are both right there. I used to get years more use out of Harley Davidsons equipped with batteries in the old kick start days that way. While not making a "new" battery out of them, the upside down flush with water, refill with acid worked wonders for a guy with lots more time than money. | ||

Glenn, we are both coming up short here, and I should have clarified that pure acid is for new batteries, and electrolyte is for those that have been drained and cleaned, and that may have sulfation and scaling on the plates. Let's keep at it, and between us we'll solve all of the 'Boards problems. Cheers...JJ | ||

If you need acid, go to a Phish concert. Look for the buses in the parking lot with all the funky colors. You're welcome.  | ||

Amen to Marc's post. Get the most of your battery after recharge is to check specific gravity reading. Before SG reading do the following; Surface charge (or counter voltage) is the uneven mixture of sulfuric acid and water along the surface of the plates as a result of charging or discharging as the electrolyte has an opportunity to diffuse in the pores of the plates. It will make a weak battery appear good or a good battery appear bad. You need to eliminate the surface charge by one of the following methods after recharging a lead-acid car battery: 1) Allow the battery to sit (or rest) without discharge or recharge for between six to twelve hours in a warm room, if possible, to allow for the surface charge to dissipate. (Recommended method. 2) Turn the headlights on high beam for five minutes, turn them off, and wait five to ten minutes. 3) With a battery load tester, apply a load at one-half the battery's CCA rating for 15 seconds and then wait five to ten minutes. 4) Disable the ignition, turn the engine over for 15 seconds with the starter motor, and wait five to ten minutes. 5) Apply a load that is 33% of the ampere-hour capacity for five minutes and wait five to ten minutes. 6) With a battery load tester, apply a load is one third the battery's amp-hour rating for five minutes and wait five to ten minutes. Electrolyte is at 80° F (26.7° C), and the specific gravity reading is 12.65 for a 100% state of charge. If you have higher than 12.65 @ 80F than you shorten battery's physical life. Otherwise weaken battery load if it lower SG after all of above. http://www.uuhome.de/william.darden/carfaq4.htm#inspect FWIW Sojourn for Christ, Jerry |
