What is the post orientation of a EU1L battery

Click For Summary

Discussion Overview

The discussion revolves around the specifications and classifications of EU1L and U1L batteries, particularly in the context of garden tractors. Participants explore the meanings of the letters and numbers in the battery designations, as well as differences in performance metrics such as cranking amps.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests that "U" in EU1L may refer to utility, and "L" indicates the positive terminal post orientation facing left.
  • Another participant proposes that "E" could identify a classification system, possibly European, while providing dimensions for U1 and U2 battery sizes.
  • It is noted that U1 and U2 are the only sizes specified for garden tractors, with BCI / Group numbers provided for these classifications.
  • A participant expresses curiosity about the difference in price between U1L and EU1L batteries, questioning what additional value the "E" designation might represent.
  • One participant highlights a difference in cranking amps, noting that the EU1L has 365 amps compared to 275 amps for the U1L.
  • There are suggestions to consult manufacturers for datasheets to gain more clarity on the specifications.
  • A later reply indicates that the datasheet available does not address the specific question regarding the "E" designation.

Areas of Agreement / Disagreement

Participants do not reach a consensus regarding the meaning of the "E" in EU1L, and multiple competing views about battery specifications and classifications remain unresolved.

Contextual Notes

There are limitations in the discussion regarding the lack of clarity on the "E" designation and the dependence on manufacturer-specific definitions for accurate interpretation of battery specifications.

Anyone know what the specification of EU1L is in a garden tractor battery? I am assuming "U" is utility, and "L" is the positive terminal post faces left viewing the battery's face or front. If so, what is the "E" and "1"?

Welcome to PF.
E will probably identify the classification system. Maybe European?
U1 is a physical size LxWxH = 195 x 125 x 155 mm.
U1RMF is size U1, Right hand positive, maintenance free.
U1MF is size U1, Left hand positive, maintenance free. (L is sometimes assumed if not R).
 
There are only two sizes, U1 and U2. They are only specified for use on garden tractors. General - Utility Batteries, 12-VOLT (6 CELLS)
U1, U1R and U2 are BCI / Group numbers. Battery Council International give sizes as U1 = 197 x 132 x 186 mm, and U2 = 160 x 132 x 181 mm.
 
Thanx much, that elucidates most of the puzzle, however, E may be a classification, but the batteries I'm looking at were manufactured in PA. These are two Duracells I am considering, one, a U1L at one price, and a EU1L at a cost of $5.00 more, so I'm curious as to what I might be paying for if I splurged for a whole $5.00 more (tee-hee).
 
Just an update, having gone to compare the batteries: still unclear on the "E," but the cranking amps on the EU1L is 365. whereas the U1L is 275.
 
Ask manufacturers for datasheets and you'll be smarter.
 
But this ^-^ relates safety and maintenance, not data sheet about technical performance
 
Wow
