Operating Temperature Range Self Discharge Terminal & Torque Specications Best Practices
Maximum Limit -4°F to 120°F
(-20°C to 49°C) with proper temperature
compensation controls. Lead acid
batteries are temperature sensitive: refer
to the temperature / capacity projection
chart to identify available capacity at the
application operating temperature.
Application Note: Maintain a state
of charge greater than 60% when
operating batteries at temperatures
below 32°F (0°C).
Approximately 3%
per month at 80°F
(27°C). Rate of
self discharge will
vary depending
on storage
temperature.
Freshening charge
recommended for
inventory at
75% SOC voltage.

50 to 70 in-lbs / 6 to 8 Nm
Stainless Threaded Terminal:
100 to 120 in-lbs / 11 to 14 Nm

Battery terminal connections
should be secured and tight at all
times. Replace torn or damaged
cabling or connectors.
Safety is Your Responsibility! Keep sparks, flames and cigarettes away
from batteries at all times. Maintain good ventilation when working on or
charging batteries.
Keep batteries and terminal connections clean, dry and free of dirt and
corrosion. Do not tamper with vent structures.
Optimize the life of your batteries by limiting duty cycle depth of discharge
to 75% or less.
Charging service must be performed with equipment configured to support
the charging recommendations herein. Opportunity charging service can
be performed when batteries are no more than 50% discharged. Batteries
must be fully recharged after the termination of duty cycle usage. Chronic
under-charge or over-charge will shorten battery life.
