The duration of the storage period, from manufacture date (date-code marked on
the batteries) to the first recharge, must not exceed:
12 months at an ambient temperature of less than 20°C
9 months at an ambient temperature from 21°C to 30°C
5 months at an ambient temperature from 31°C to 40°C
It should be noted that batteries stored at higher temperatures must have a
reduced storage period before recharging.
Storing a battery for longer without recharging it leads to sulphation of the plates.
This reduces the performance and shelf life of the battery. If the battery is stored for
too long it may not recover full performance and/or life. (
See the TECHNICAL
MANUAL corresponding to the type of battery).
The respect of these advices allows to store the batteries for few years.
5/ GENERAL INSTALLATION CONDITIONS
The following chapter should be read carefully before starting the installation of
YUASA batteries.
5-1/ POSITION OF THE BATTERY
It is recommended that the battery be installed in a clean, dry and cool place.

The ground must be flat and able to bear the weight of the battery.

Install the battery in a well-ventilated place so as to maintain an ideal
temperature for the battery:
An ambient temperature of 20°C+/-5°C is optimal for the performances and
service life of the battery.
An ambient temperature of less than 20°C reduces the efficiency and
performance of the battery.
An ambient temperature of more than 25°C reduces the service life of the
battery.

During installation of the battery, make sure there is sufficient room around the
battery, the cabinet, stand or the rack. This is to ensure that future interventions for
monitoring or performing maintenance of the battery are easier and safer. Avoid
installations against a site wall or cabinets with more than 3 rows of batteries or more
than 600 mm deep.
