4.3 Battery

There are one lithium-ion (Li-ion) battery 3.6 Ah
availiable for the SR 500 and are good for at least 500
charging cycles. One battery is required to operate the
SR 500 Fan Unit. The charging time is 1.5-2 hours.
The fan operating time is up to 13 hours.
On delivery, the battery fitted in the fan unit is provided
with protective tape over the terminals. New batteries
must be charged before they are used for the first time.
The battery need not be discharged before it is
charged. Remove the battery from the fan unit and
remove the protective tape. To charge the battery
proceed as follows:
• Place the fan upside down. Grip the fan with one
hand, with the thumb placed over the battery. Fig 3.
• The battery cover locks the battery. Raise the cover
a few centimeters, push with the thumb resting on
the battery and withdraw the battery. Fig. 3.
• Check that the mains voltage is between 100 V and
240 V.
• Connect the battery to the battery charger. Fig. 2.
The charger carries out charging automatically in three
stages:
1. Orange LED - The battery is being charged at
constant, maximum charging current up to
approximately 80% of battery capacity.
2. Yellow LED - The battery is being charged to full
capacity at constant voltage and gradually
decreasing charging current.
3. Green LED - The battery is fully charged and the
charging current is switched off.
• When charging has been completed, pull the plug
out of the socket before separating the battery from
the charger.
• Push the battery back into the battery
compart¬ment. Check that the battery has been
pushed in as far as it will go and that its lock is
operative.

Storage

After cleaning, store the equipment in a dry and clean
place at room temperature. Avoid exposing it to direct
sunlight. A cool well-ventilated area in the temperature
range of 50 to 77ºF (10 to 25ºC) [at a relatively humidity
less than 70%] is ideal to minimize degradation while in
storage. Batteries in storage do not retain their full
charge indefinitely. Sundström recommends that
batteries not in use be charged at least once per year.
When not in use do not store the SR 500 Fun Unit with
the battery installed. Leave the battery connected to
the Sundström charger (SR 513) store the battery
separated from the SR 500 Fan Unit.
WARNING: If the battery shorts or overheats it can
cause a fire, venting of gas or fumes, or leakage of
electrolyte that can cause personal injury.
Performance & Conditioning (charging and
recharging)
The SR 500 Fan Unit can provide up to 13 hours of
operating time.
The NIOSH laboratory performance service life
(breathing machine operating at a rate of 24 respira-
tions per minute, minute volume of 40 l/m for a period
of 4 hours) is not guaranteed in real situations. The
actual service life of a PAPR will depend on the charge
of the battery, condition of the battery (batteries
degrade over their lifetime), battery operating
temperature, workload of the user (breathing rate of
variable speed PAPR) or resistance to air flow
associated with clogging of the filtering components,
prolonged periods of operation, etc.
For best performance of the SR 500 Fan Unit charge
the battery immediately after each use. The Li-ion
rechargeable battery should not be completely
discharged. Batteries in poor condition could cause the
"low battery warning" time to be reduced or the PAPR
air flow to decrease rapidly.
WARNING: There is no field maintenance on Li-ion
batteries. Do not attempt to disassemble or repair
a damaged battery. This may result in serious
bodily injury or death.
Shelf Life & Disposal
The SR 500 system has a shelf life of 5 years from the
date of manufacture. However, note that the battery
must be charged at least once a year.
The battery contains no mercury, cadmium or lead, and
is therefore not regarded as environmentally harmful
waste.
WARNING: Do not dispose of the battery in a fire as
this may cause the battery to explode and may
result in serious bodily injury or death.

Battery Safety

WARNINGS:
• Always recharge the battery before it has
become fully discharged.
• Do not store, use or condition a battery that
shows signs of damage such as budging,
swelling, disfigurement, or liquid excretion. This
could cause serious personal injury.
• Do not replace a battery when the PAPR is
turned on or when the PAPR is operating. This
could cause damage to the battery.
• The battery may be charged only with a genuine
Sundström charger (SR 513).
• The charger may be used only for charging the
batteries for the SR 500.
• The charger is designed only for use indoors.
• The charger must not be covered while it is in
use.
• The charger must be protected against
moisture.
• Never short circuit the battery. Do not carry or
store a battery with other metal objectives that
could cause a short circuit.
• Never try to dismantle the battery.
• Never replace a battery with another type of
battery and only use the Sundström SR 502
battery.
• Never leave a battery in direct sunlight or close
to a heat source for extended periods of time or
discard in a fire as chemical leakage or
explosion could occur.
• Never immerse a battery in water or liquid.
• Never disassemble a battery, it can leak toxic
chemicals (e.g. electrolyte and in some cases
explode.
