Lead-acid batteries for motorcycles – Specification
1Scope
This standard specifies the lead-acid batteries for motorcycles used for the starting, lighting and ignition of motorcycles (hereafter referred to as “batteries”).
2References
The title of the standards publications referred to in this standard are listed on the inside back cover.
3Definitions
For the purpose of this standard, the following definitions apply:
3.1
lead-acid batteries for motorcycles
a battery intended to be mounted on a motorcycle for the power source of starting, lighting, ignition, etc
The battery having such function resulted from its construction that supplement of water is not necessary because the oxygen gas generated from the positive plate react to and absorbed in the negative plate is called “sealed type battery”, and other batteries than this are classified as “vented type battery”.
Further, that battery of which high rate discharge characteristics have been improved by using the separators of lower resistance than that of conventional one among the vented type batteries is called “high performance type battery”, and the battery other than this one is called “normal type battery”.
3.2
nominal voltage
the standard voltage to be used for the voltage marking of a battery (V)
3.3
capacity (10-hour rate)
the product of the 10-hour rate current and the hours until a cut-off voltage of discharge is reached or the quantity of electricity when discharged down to the cut-off voltage of discharge at a 10-hour rate current (Ah)
3.4
10-hour rate current
the term which expresses the amount of charging current and discharging current of a battery, and the value of which is equal to the quotient of the value of capacity (10-hour rate) by 10(A)

3.5
