7-5/ GENERAL INFORMATION
The battery terminals and connectors must be clean and have no traces of
corrosion. If this is the case, following the transport or storage conditions, it is
necessary to clean the terminals with a cloth and a sodium bicarbonate solution.
Contact Yuasa for details concerning the dosage and procedure.
Terminal greasing is not obligatory except when batteries are installed in
corrosive atmosphere (saline atmosphere, ...)
For the cabling, use insulating boots or caps for the ends of the connectors
attached to the batteries or charger.
In order to limit the risk of contact with the battery terminals, assemble the
protection guard or terminal covers on each battery as it is connected.
If the battery terminals are insulated by terminal covers, the use of a walkway
is not necessary. Use an insulating mat or insulating stool each time a battery with a
voltage of more than 120V is handled.
WARNING: DISCONNECT THE CHARGER OR APPLICATION BEFORE
TOUCHING THE CONNECTORS.
8/ CHARGE:
For the charge of the batteries, refer to the TECHNICAL MANUAL of the
corresponding type of battery.
It should be noted that YUASA
NP/NPL/SW/SWL/EN/ENL/UXL/FXH/YFT/YUCEL batteries are delivered ready
charged. Their state of charge will depend on the length of the storage period since
they were last charged. Before complete discharge (autonomy trials), it is therefore
recommended that chapter 12, AUTONOMY TRIALS, be studied carefully.
For info:
Floating charge voltage at 20°C per cell:
- NP/NPL/SW/SWL/YFT/FXH/YUCEL battery: 2.275V
- EN/ENL battery: 2.26V
- UXL battery: 2.23V
The voltage of the charger, and the adjuster if necessary, should be verified at
least once a year.
