4.1 General
Batteries should be unpacked, installed and charged as soon as possible after receipt. However,
if this is impractical, follow the instructions below for storing the battery before installation.
4.2 Storage Location
1.
Store batteries indoors in a clean, dry and cool location. Storage at higher
temperatures will result in accelerated rates of self-discharge and possible
deterioration of battery performance and life.
2.
Do
NOT
stack pallets.
DAMAGE MAY OCCUR AND WARRANTIES MAY BE VOIDED.
3.
Recharge the PowerSafe
®
mP Series before their Open Circuit Voltage (OCV) reaches 2.11 Vdc.
4.
If no voltmeter is available, the maximum storage time from shipment to initial charge is six
months for batteries stored at ambient temperatures no warmer than 77˚F (25˚C). For storage
temperatures greater than 77˚F (25˚C), the battery must be recharged one (1) month sooner
for every 5˚F (3˚C) increase above 77˚F (25˚C). See Table 4.1.
4.0 BATTERY STORAGE BEFORE INSTALLATION
TABLE 4.1
STORAGE TEMPERATURE
STORAGE TIME
32˚F (0˚C) to 50˚F (10˚C)
9 months
51˚F (11˚C) to 77˚F (25˚C)
6 months
78˚F (26˚C) to 92˚F (33˚C)
3 months
If storage time exceeds the storage time recommended in Table 4.1, give the battery a
freshening charge before the end of the recommended storage interval. See Section 16 for
charging information.
PowerSafe
®
VRLA mP Series batteries must be charged in the horizontal position. Charging
in the vertical position may void product warranty.
5.
Repeat the
freshening charge
(Reference Section 16) for each additional storage interval
until the battery is installed.
Storage at higher temperatures will result in accelerated rates of self-discharge and
possible deterioration of battery performance and life. Storage times exceeding the
above may result in plate sulfation, which may adversely affect electrical performance
and expected life.
6.
Maximum total storage time prior to installation is two (2) years from date of shipment
from the factory to the customer.
Freshening charges
are required before the end of the
storage time period, or more frequently, as noted in Table 4.1.
7. FAILURE TO CHARGE AS NOTED VOIDS THE BATTERY’S WARRANTY.
