Battery life is directly dependent on how deeply the battery
is discharged; the deeper the discharge, the shorter the
battery life.
Examples of Operating Times Based On Load
If you plan to use the PORTAWATTZ 400 with a specific product, the
chart below (table 2) provides approximate operating times based on
battery size. These operating times assume the battery is fully
discharged, so be certain to purchase double the battery size shown if
you will frequently operate the product for the time period stated.
6.3 Important Information About Batteries
These are points to keep in mind when using or installing a battery:
·
With the exception of sealed, gel cell batteries, lead acid batteries
emit hydrogen and oxygen gases, and sulfuric acid fumes when
recharging. Make sure the battery compartment is vented to prevent
accumulation of gases and fumes and do not install electronic
equipment in these areas. Also, do not smoke or have an open
flame when working around batteries.
·
The capacity of lead acid batteries is temperature sensitive. The
stated capacity of a battery assumes the air temperature is 77ºF
(25ºC). When the air temperature drops to 0ºF (20ºC), the actual
amp-hour capacity will be about one-half of the batterys rated
capacity.
·
Do not leave batteries in a discharged state for more than two
days. Batteries left discharged too long undergo a chemical process
called sulfation, which can permanently damage the battery.
·
Batteries self-discharge over time, even when they are not used.
Recharge your battery every 3 months to maintain its rated capacity.
Store batteries at room temperature; batteries subjected to high
