User Manual

u Upon receipt of your batteries or new equipment fitted with
batteries, examine the batteries for signs of moisture or impact
(which may indicate damage in shipment).
u If there is evidence of damage – notify Crown Battery or the
equipment supplier to make a damage report.
u Charge the batteries before deploying the products to service.
Charge the batteries in a well-ventilated area using the battery
charger that is matched to the battery application.
u AGM batteries can be stored safely for up to a year before
requiring inventory maintenance. With a self-discharge rate of 2
to 3% per month and sealed design, the product can be stored
in ambient temperatures below 80°F / 27°C with full retention
of product integrity. Take precautions to ensure batteries are
fully charged prior to storage, are kept clean and dry – and are
protected from impact and free of any connections that may cause
parasitic loads.
u CROWN1 ™ AGM batteries are certified non-spillable batteries
and are not restricted for transportation by Air (IATA / ICAO),
Surface (DOT) and Water (IMDG).
u AGM batteries can be recycled and should be returned to an
authorized battery disposal agent for recycling. Refer to
www.batterycouncil.org for more information about
battery recycling.
Maximizing Your Investment
AGM batteries deliver all of the power required by EV, motive power
or Renewable Energy systems. One full cycle represents a full battery
recharge followed by a complete battery discharge period.
Battery life is usually measured in cycles or in terms of ampere-hour
throughput delivered to the application – but in practical terms your
batteries will deliver reliable performance and a strong R.O.I. when
maintained with proper charging and attention to the best practices
identified in this document.
Other Factors That Affect Battery Life
and Performance:
u Batteries are rated in ampere-hours (Ah) and are designed to
perform a specific workload within an established period of time.
Increasing battery depth-of-discharge has a direct effect on cycle
and life performance – with frequent deep discharge resulting in
shortened battery life.
u Optimize the battery life by limiting duty cycle depth-of-discharge
to 75% or less of available discharge. A 75% depth-of-discharge
corresponds to end-point voltages of 1.84 Volts per Cell – or 5.52
Volts for 6-volt batteries, 7.36 Volts for 8-volt batteries and 11.04
Volts for 12-volt batteries.
u Batteries should always be recharged immediately following the
completion of a duty cycle discharge. Never allow batteries to
remain in a fully discharged period, otherwise permanent damage
will result.
u 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.
u CROWN1 AGM batteries can operate within a maximum
temperature limit of -40°F to 120°F (-40°C to 49°C) with proper
temperature compensation controls. Application Note: Maintain
a state of charge greater than 60% when operating batteries at
temperatures below 32°F (0°C).
u After regular charging service, batteries should be allowed to cool-
down or rest for 6 to 8 hours before the next duty cycle. If a battery
is ever hot to the touch, allow it to cool to ambient temperature
before discharge or charging service.
u Keep battery connectors and cabling in good condition.
Replace damaged or torn cabling or connectors as damage
to these components will result in hazardous operation and
poor performance.
