Re: Power Wise QE Not Shutting Off?
Thanks JohnnyB! I get 18 holes in with the SOC meter @ a bit above 50% or better so range is fine so far. I always plug in the charger after the days use. The amount of water consumption startled me. I checked them monthly, topped them off (not needing a lot) until a few weeks ago when the cart barely limped home. Batteries were nearly dry! Filled them (always use distilled water), charged them and seems OK now, but having to add water weekly now which is why I asked the original question wondering if the charger was staying on and boiling off the water. Anyway, time to buy that DPI charger and try to ooch along these batts till spring.

Re: Power Wise QE Not Shutting Off?
One of the nice things about using a charger that float charges is starting your trips with a battery pack that is charged as fully as it can be. If you use your cart every day, the difference may not be very noticeable, but if you only use your cart two or three times a week, the difference will be noticeable.
Attached is a Technical Service Bulletin from US Battery addressing chronic undercharging. The good news is some of the storage capacity loss is recoverable with proper charging. The bad news is, at best, they will only recover to 4 year old batteries that have aged normally. Good luck. Let us know what happens. |

Re: Power Wise QE Not Shutting Off?
Very helpful, JohnnieB, thank you! DPI is on the way. It is, of course mildly irritating that EZ-GO would sell a mismatched charger & battery pack. It appears that US Battery was fighting back with their testing and TSB.

Re: Power Wise QE Not Shutting Off?
Crown was never offered from Ezgo as far as I know. And Ezgo's claim on the charger profile is that it is strictly Dv/Dt, so no "profile" is needed.

Re: Power Wise QE Not Shutting Off?
These are US Battery (I mistakenly wrote Crown in the original post) which EZ-GO used at the time I bought the cart. Not sure if they still do but these are original to the cart.

Yep, US were common for several years.

Re: Power Wise QE Not Shutting Off?
And so that begs the question of what new batteries to get when these give it up. Appreciating that switching to 6 8V would be optimum vs. the 4 12V that it has, I will likely forego the expense of a new rack, cables, etc and go with the 4 12V configuration. US Batteries or Trojan T-1275?

Trojan T-1275: AH @ 20hr rate = 150AH Runtime @ 56A = 102 Minutes Weight = 85lbs US Battery US-12RVX-XC2: AH @ 20hr rate = 155AH Runtime @ 56A = 110 Minutes Weight = 86lbs Looks like US Battery has a slight edge in all three categories and the DPI charger has a charge profile specifically designed for it. Of course, the Trojan offering is a close second and the DPI has a charge profile specifically designed for it also. So it more or less boils down to which brand you can get for the best price in your geographic location. |

The constant voltage DPI uses during the absorption charge phase for a Trojan Battery 48V pack is 56.4V while 60.0V is used for US Battery. Also, the dV/dT (change in Voltage over change in Time) rate could be different. US Battery recommends a rate of 4 mv/cell per hour, but I cannot find Trojan's recommended dV/dT rate listed anywhere. |
