Battery AH and Deep Cycle type & Charger suitability

Click For Summary

Discussion Overview

The discussion revolves around the suitability of a specific battery for a charger, focusing on the battery's amp hour (AH) rating, its classification as a deep cycle battery, and the interpretation of a charging time chart from the charger manual. Participants also share tips for maintaining battery life.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks assistance in determining the AH rating of their EverStart U1R-7 battery and whether it is a deep cycle battery.
  • Another participant suggests that the numbers "275" and "230" on the battery may indicate cold cranking amps (CCA) and proposes using the corresponding time in the charger manual's chart.
  • A different participant expresses interest in an automatic battery charger/maintainer, specifically mentioning the Battery Tender as a suitable option for maintaining battery life.
  • One participant questions how the charger output rating (10 Amps DC) relates to the hours charged and seeks clarification on which column of the chart applies to their battery.
  • A participant identifies the battery as a flooded lead acid type, explaining its characteristics and limitations regarding deep discharges compared to AGM and GEL batteries.
  • Another participant humorously suggests that the original poster's battery may have died since the post date is from 2011, implying a lack of relevance to the current discussion.

Areas of Agreement / Disagreement

Participants express varying levels of understanding regarding battery types and charger compatibility, with no clear consensus on the battery's AH rating or its classification as a deep cycle battery. The discussion remains unresolved on these points.

Contextual Notes

Participants note the absence of explicit AH ratings on the battery and the potential confusion surrounding the charger manual's chart. There is also a lack of clarity on how to interpret the charger output rating in relation to charging time.

I am using this battery for a boat bilge pump. It's all working as expected, but what I am trying to determine is if my battery is suitable for the charger I have and if so, I need assistance decoding the CHARGING TIME chart (picture below) in my charger manual to determine how long I should charge the battery, what the battery "AH" and Amps rating are and any tips for maintaining the life of the battery are also welcome.

I've included screen shots below of my charger specification and some additional images for visual.

I apologize for my ignorance in this subject.

EverStart U1R-7 Tractor/Mower Battery Details:
-- Lead acid
-- Maintenance-free
-- Model No.: U1R-7
-- Product in Inches (L x W x H):8.25 x 5.8125 x 7.8125

This is an excerpt from my charger manual. I am having a very difficult time determining the "AH" (Apere Hour) of my battery as it is not noted anywhere I can find. And I do not know if it is considered a "Deep Cycle" battery.

Here is a pic of my charger up close:

Here is a shot of both for visual:

I see "275" and "230" on the front of the battery, but I can't read the text next to the numbers. I'd guess that one of them is CCA (cold cranking amps). If so, then I would just use the corresponding time in the manual's chart.

But... The better way is to get an automatic battery charger/maintainer, such as the http://batterytender.com/" .)

pantaz, I did not know such a product existed. I was looking at trickle chargers, but the Battery Tender seems to be a safe product to maintain the life of the battery.
 
At the top of the charge chart, there is a header titled "Charger Output Rating (Amps)". I am not sure how this relates to the hours charged. Is Output Rating related to the battery or the charger? And how would I determine which column is correct for my battery?
 
I think the answer was directly in front of my face. I see the charger says: 10 Amps DC output. I think that answers my questions. If I am wrong about this, please let me know : )
 
You have a size U1 battery. There are three different types of batteries all Lead Acid and all in the same case. What is different?

Flooded: [you have this] Based on your description this an ordinary flooded wet lead acid battery. If you poked a hole in the side of the battery, you would get cups of loose liquid sulfuric acid on the floor. This battery is designed to dissipate the heat created during a Starting type discharge, short and vigorous. Not designed to be deep discharged. Note rating is CCA [cold cranking amps] which tells you how much current you can get for a SHORT while.


AGM: Absorbed Glass Mat this is designed to support deep discharges. Not good for starting service as it has too much lead and not enough sulfuric acid to handle the heat of starting. Poke a hole in this one and you get teaspoons of sulfuric acid. The rest is absorbed in the fiberglass sponge between the plates.

GEL: Similar construction to the AGM battery, except the sponges are thinner and the electrolyte contains extras to make it into a jelly. Poke a hole in this one and you get almost no leakage. Costs more than an AGM.
 
I'm thinking that since 9-4-11, his battery has died. :devil:

You may want to look at the post date before posting. Just sayin'
