New batteries
I am looking to get new batteries for my 2009 RXV. What is the best brand out there today? I spoke with my local dealer and he said that Trojan use to be the best but they are the same as US batteries now. Is this correct? I looked and can not find any info on this. Also I was wondering the age of my current US batteries (I see a stamped code located at the bottom left that reads 2A112D2). Would this mean A = Jan and the 11=2011?

Re: New batteries
Are you having problem with current batteries?
I switched from Trojans to US batteries this year.price slightly cheaper but specs better then Trojans. Either brand good,just get highest capacity you can afford😊 |

Re: New batteries
I'm an old Trojan fan . But do notice NAPA batt is making a few in sales.
Perhaps the battery brain cells on here can enlighten us ? |

Re: New batteries
Yes I am starting to have issues (charged for long time and then the charger goes to a red blinking light). Loss of power also.

Re: New batteries
I'm pretty sure it is at least a 5-way tie for first place between (Listed alphabetically) Crown, Deka (East Penn), Exide, Trojan and US Battery, with several other brands not far behind.
The number of charge cycles a battery has is mostly determined by the average SoC (State of Charge) maintained during its cradle to grave lifespan. Climate of location where battery is used and how well maintained are other important factors also. Attached chart show estimated charge cycles available vs average SoC for 4 of the top brands. The data is published by the manufacturers, so the statistical purity may be iffy, but the trend undeniable. Since a higher capacity battery ends up with a higher SoC at the end of a trip than a lower capacity battery making same trip in same cart with same driver, etc., Higher capacity batteries (higher AH rating) last longer. Bottom line; Get the highest AH batteries you can afford and buy them locally. Also, look at the warranty. ------------ If your RXV has a 4 X 12V battery pack, convert it to a 6 X 8V for longer battery life. |

Re: New batteries
Thanks, I am planning on getting the best battery and I was planning on getting the Trojans. But I seemed as if my ezgo Shop was trying to push the US instead of Trojan. I was surprised by this so I wanted the boards opinion.

I went with Exide a few years back because it was the best bang for the buck when fuel costs and driving time was factored into the equation. They will be 7 years old in November. |

The mystery deepens even further when you look at the SG and VPC (Volts per Cell) in the SoC data provided by Trojan and US Battery. Trojan SG @ 100% Soc = 1.277 (@80°F) US Battery SG @ 100% SoC = 1.270 (@80°F) Trojan VPC @ 100% Soc = 2.122V (@80°F) US Battery VPC @ 100% SoC = 2.137V (@80°F) I'm not sure how US Battery manages to get a higher cell voltage with a lower SG, but that's what their data indicates. The Trojan data is from their User's Guide and the US Battery data was e-mailed to me from their engineering department. |
