J2185_201202: Life Test for Heavy-Duty Storage Batteries (Lead Acid Type only)

Features

Issuing Committee: Starter Battery Standards Committee

Scope

Content

This SAE Standard applies to lead-acid 12 V heavy-duty storage batteries as described in SAE J537 and SAE J930 for uses in starting, lighting and ignition (SLI) applications on motor vehicles and/or off-road machines. These applications have some of the following characteristics:

a
High levels of power are required to start the vehicle’s internal combustion engine. The need to supply this power limits the maximum depth of discharge to a fraction of the total capacity of the battery. The battery must be maintained at a charge level sufficient to perform this primary function by vehicle’s voltage-regulated charging system.
b
The vehicle’s engine powers a voltage regulated charging system that limits the charging voltage when spinning at sufficient speed and when total loads do not exceed its output limits.
c
The battery is subject to deeper discharging than a typical automotive application as a result of the following conditions:
- High daily hours of use
- High numbers of starts per day
- Electrical loads often exceeding charging system output (at idle)

Batteries will be classified into two types for this life test. Type 1 applies to BCI group sizes typically with reserve capacity (RC) rating of 250 minutes or less. Type 2 applies to larger batteries typically with reserve capacity greater than 250 min.

Rationale

Content: A Rationale is required explaining why the document is being revised. Since the original publish date of this document there have been significant advancements in lead-acid storage battery technology for use in heavy-duty applications. This document addresses the key considerations for performing life test on different lead-acid battery technologies, specifically, flooded and valve-regulated types, and effects on the associated test methods.
