A few suggestions: 1) If you have not done so yet, talk to Club Cart and see if they can provide you technical support for this issue. If this is a materials problem, they likely have experienced this problem on other carts and hopefully can offer you or guide you to a proper solution. 2) If you are not able to determine an effective solution from Club Car, you should try installing corrosion resistant fasteners. I like using both correctly sized washers and nuts as fasteners, which provide an effective clamping force onto your cables and terminals. Galvanized coated fasteners might be a good material to try. I was originally thinking that cadmium coated is the way to go, but there seems to be a lot of concern on the safety and environmental effects of cadmium. See: https://www.finishing.com/4000-4199/4144.shtml and http://www.deltaspecialtycoatings.com/capabilities.php for some interesting (to some people) reading. 3) You mention that "I note that the terminals are usually protected with terminal grease, so i don't think this is the issue." Is the terminal grease that you are using is also sufficiently covering the nut to protect the entire connection from corrosion? I note that a lot of people on this forum use a spray on type corrosion protector such as CRC Battery Terminal Protector or NOCO NCP2 and I believe that they have acceptable results. 4) I have also read on this forum (and follow this practice) of fully venting the battery compartment by lifting the seats when charging to allow the acid gases to disperse which can aid in preventing corrosion. 5) High quality cable connectors I believe will pay dividends if you need to replace them too. I have used Ancor Marine Grade Electrical Heavy Duty Tinned Copper Lugs and believe that they are worth the extra cost. 6) Can you possibly post a picture of an affected terminal, lug and nut? This might help to spur on a few more responses. I hope that you can resolve your corrosion issues. And please keep us informed of your results. Regards, 3CW |

Re: battery cable Nuts?
Threecw
Thanks for your informative response. As the carts are now in storage for the winter season, i will have to gain access to take a picture. To start with, all cables and clamping nuts are as supplied by our UK distributor and i queried the fact that there are no washers and the cable lugs looked cheap and nasty to which i was told, "thats how they are supplied by Club Car" and any further discussions i was basically fobbed off. The cables look so poorly made that the few i have made myself have shown no corrosion whatsoever using locally supplied cable and lugs. so your comment on using high quality certainly has its merits. I will try to get a photo when i can and post it here, but it may be a while to find who has the keys to the lock up. During winter there is a smaller staff on site for the pro shops and no one seems to have keys for the compound. Your comment about washers brings me to another theory i had as these carts were supplied with no washers under the nuts and therefore maybe not enough contact area for good electrical contact. I wondered about heat being an issue due to discolouration of the lugs which also seem too small in surface area and very thin material. The cable lugs are not the closed end type i have used in the past on EZGO carts and crimp on to the cable with two overlapping tabs. I wonder if the carts are shipped to the UK without batteries and cables and the UK distributor is having them made cheaply? I also note that the cables going to the rest of the cart are well made, the ones i am concerned about are those that connect the battery pack together. I need to speak to someone sensible at the Uk distributors as all i have spoken to so far are just fobbing me off saying it is down to poor maintenance. Regarding your comment about the terminal grease, the answer is yes, full coverage on all that i have inspected although i have considered using the spray type as you suggest. As an afterthought, i wonder now if the issue is more down to battery cleaning. a few months ago I had to advise the Marshalls that they need to clean down the batteries with bicarb to neutralise any spilled electrolyte on the battery tops as some of the autofills had leaked. So, looking at the price of battery cables here in the UK from the distributor, compared to the quality, i think we are being ripped off big time and hopefully if i can prove that the poor cables are the issue along with being fitted without washers i will go back to the distributor for an argument LOL. I dont trust the distributors at all due to them not telling the truth about complaints from other customers regarding quality control. I have had several issues of poorly manufactured parts being supplied recently and again have been fobbed off with comments like " never heard of that" or "no one else has complained about that" even when one of their engineers came to site for some insurance repairs and totally agreed with my complaints and often see's it when visiting other courses! To be honest i am at the point of recommending we go to another brand of cart when we replace the fleet next year. Edit. Just an afterthought, you mention lifting the seat to vent the gasses given off. Surely my understanding is that is is only hydrogen and oxygen being gassed off? so should not affect corrosion, just creating an explosive atmosphere with the hydrogen . correct me here as This is what i was told when doing my EZGO training.i am probably incorrect |

Re: battery cable Nuts?
There is a keyword in there: autofill.
Your batteries are being overfilled. Then during charge, they are boiling over. What you are describing is being caused by "wet acid". Put new stainless nuts on terminals and throw away the autofill system on the cart giving you the most trouble and monitor water levels weekly. The problem will go away. |

Re: battery cable Nuts?
First, a bit of history. I also maintain a fleet of 2015 Precedents. At one of our last Pro Ams we had a Pro from the UK. He said he thought his course was one of the hillyest courses in the world until he played ours. He said it was like his course on steroids. Anyhow to your problem. These carts are starting there 3rd year and our 2012s were traded after 4 years of service. We are a year round course in the foothills of the Blueridge Mountains in South Carolina with a fairly mild winter and some snow. I do all the maintenance, repairs, lubing and watering myself. I have never had a corrosion or cable problem with the factory batteries and cables so I can't help you with your problem other than to say it is not normal. My carts have one point watering, Power Drive batteries and Eric chargers and I water them and wash them off once a month faithfully. Club Car uses stainless steel nuts with no lock washers. Most battery manufactures specify not to use washers or lock washers. I have never put terminal protector on our carts. We have 63 course carts and on some busy days, some have to go out twice a day.
I know I have not helped you with your problem but I just wanted to let you know that it is not normal. Harry |

Re: battery cable Nuts?
Havent seen a actual fleet manager on the forum myself yet ,dont think cartmaster does the watering / and the hydro-systems really gets a bad rap here. i myself have taken mine off due to overfilling and under filling with a one year old system (US Batteries) . if you maintain 63 carts that all have that system ,, what percent of them start Overfilling (excessive fluid on tops) after the first year lets say ..and what brand is important . just curious
