Re: 05 PDS question
Thanks for the help. I will change the batteries out when my money tree blooms this spring.

Re: 05 PDS question
If you trust measurements from $1.54 tools, your results will reflect your tool choices. Cheaper is not usually the best answer. Take one of those floating ball testers into a chemistry lab and ask the teacher to use it for the next measurement exercise. It is not "just as good" as the real deal.

The article at http://www.corradoworld.com/article/batteries-101.html shows how one man has used his for 25 years. For most of us the $1.50 four ball specific gravity battery tester will give us the info we are looking for and without less acid spills having use the three common types. Here is a 1923 ad for the brand I picked up at Walmart and like the one I saw at O'reilly's last night for $1.49. Look that the price increase amount. http://books.google.com/books?id=YNo...tester&f=false Again my post was just to help show the error in claiming I was using an antifreeze tester to check SG values in wet cell batteries. The 1923 floating ball tester ad predates the invention automotive antifreeze that the floating ball testers test today. |

I think we all can agree the usefulness of any testing equipment/musical instrument/race car can be limited by the skills of the person using the device. What does specific gravity mean in relationship with deep cycle batteries is a good starting point in understanding what is being measured. As for the cost of battery hydrometers they are all peanuts. Concrete is harder on the $9 one from NAPA (Balkamp Model 700-1145 Battery tester) than the $1.49 one from O'reilly Auto Parts I learned however. |

After your ride wait an hour for them to recover some and pull the readings again. Hopefully they will all be within .1 volts but should you find a weak link hurting the life of the entire bank you might replace it if you could find 'good' older battery to replace the weak one. Hey spring is right around the corner. If by chance your cart had been in storage for a while before your last topping off charge and ride repeat this cycle three times to see if it helps your run time. The EZGO charger is a good charger with a lot of research behind it and three back to back cycles may help your run time. I am talking about go for the ride and charge until it actually cuts off. scottyb pointed out to me the charger can still be doing some cool stuff even when the amp meter hand is at zero. I proved him right with the VOM (volt-ohm meter). I was ready to pull the plug on the charger because it LOOKED finished by the charger meter but VOM reading was 43.8 volts meaning the charger was still working. Some additional desulfation/equalization I expect was still taking place. The bank voltage will drift back down to 39 or < voltage after the charge has truely finished. If you have a Kill-A-Watt meter it will report when no power is being used by the Ezgo charger. Let us see if you and milk a little more life out of these in the mean time. |
