Default Old batteries with desulfator

Thanks for the follow up, but it's hard to put a lot of validity into the tests when you keep saying "cheepo desulfator" lol ...I don't feel the name brands are expensive enough to warrant the risk of a cheepo thing worsening your already aging batteries. Chinese-anything is almost synonymous with cheap ripoff that don't work/last. Those are my opinions....

Opinions aside, these are the facts; an unbalanced pack will absolutely destroy your batteries faster. Adding one new battery to a dying pack is like throwing money into a fire to stay warm. The new battery will discharge at a different rate and charge at a different rate overcharging or undercharging it or your other batteries every time you plug in after a ride. Your new battery is guaranteed not to last as long as it should. I wouldn't wait another day to replace the other five. Not just my opinion but those are the facts of battery pack 101. Take it from a guy who had a mismatched set of batteries once.

Hey guys a great source for distilled water is a dehumidifier . also some bottled distilled water has sodium in it ,not good for batteries. Thought i'd mention it , a lot of people I know never think of that free source .pass it on.

Sorry no dehumidifier water is not a good source for distilled water...

Although water from a dehumidifier is condensed from the air, it is only as clean and pure as the air space you are dehumidifing. House air is not very clean. Just look at your furnace filter. If you have pets or if you heat with wood, the air can be very dirty. The "dirty" air passes over the wet coil in the dehumidifer and particles "cling" to the water and drip into the tank with the water. It varies from house to house. By no means could you call this distilled water but it might be much better than tap water for mineral content depending where you live and what particles are in your air.

Dehumidifier water is not clean. It might be ok if you filter it but it's not worth the effort. Buy distilled water. It's cheap.

I had a dehumidifier once, it makes lots of water but It would accumulate lots of crap in it also, no way would I put it in expensive batteries to save a quarter. In theory it is true the water under perfect conditions would be almost pure but remember distilled water is completely evaporated water molecules captured in a close loop system then cooled & released in coil tubes into a clean environment and container.

I don't disagree with you. I have heard this advice before. As a matter of fact, I had originally intended on replacing the other five batteries around the middle of next month. And the gentleman that sold the single battery to me said I would be fine with that. But, now I am wanting to start measuring the charges on the batteries. I have a digital meter and I am curious as to how this works. All the old batteries are charging to a sustained charge (sitting over night after charge) with a minimum charge of 8.49 volts up to 8.51 volts. I have only charged the new one with the pack a couple times and haven't measured it yet because I am sure since it is not broke in, it will not give me a accurate measurement. I am still curious as to whether or not that little desulfator was instrumental in damaging the first battery in the pack, or if it is just a coincidence. I have received digital voltage meters to be installed in the dashes of both golf carts when I get a chance. Right now, I am still working on the interior of our home. The wife is snapping the whip for me to complete our interior project.
I don't doubt what you said regarding possible damage to the new battery. But, I am not ready yet to give up on the other batteries. It may cost me the price of one battery. Maybe when I get the new batteries, if I have problems with the presently new one, maybe the warrantee will cover it. Maybe not. This might be a hundred buck experiment. Plus, it will give some of you the good feeling of being able to say "I told you so." Or, "I could have told you that."
I am still debating as to whether I want to install a desulfator on my cart. If I use my cart, I charge it with the golf cart charger. If it is going to sit a few days or week, then I put the maintainer on it. I am still wondering if having the desulfator and the maintainer on it at the same time is detrimental to it.

Whenever I can't get much out of the old batteries I have now I may buy some of that stuff they claim to rejuvenated old batteries, $30 bucks worth a shot, I have nothing to loose. If nothing happens then they will be traded in for new ones LOL.

I think that is their entire business model.

I agree with volt_ampere, if you follow their procedure, except leave off whatever snake oil you supposed to put in the batteries, You will have better results.

I would make an analogy to those "diet pills" with the small disclaimer "must be used with a regular exercise program and a healthy diet".

Just follow the advice of the disclaimer and forget the pills.

The same applies to electronic desulfators, You need to watch out for the carefully crafted claims they use.

Rather then focus on the science of the mysterious resonance frequency of the crystals that will cause them to burst, the more important fact is that those are typically the crystals that would normally be dissolved back into the electrolyte as part of regular charging anyway.

They really do close to nothing on the hard set sulfate crystal caused by battery negligence.

But then again, It takes several discharge and recharge cycles back to back for the device to work better....

You can start to see the pattern of the process vs the product being the key element.

I plan on getting new batteries once these can't drive me around the block anyways but I hear you on the smoke and mirrors of product sales and probably impossible to prove one way or the other with a large enough cost to make it not worth it.
