ES210 Hardware Guide: Installation

Once the battery compartment is closed, you can power up and
operate the Bridge while the battery is charging.
2.1.2.2 Battery Charging and Power Requirements
The ES210 Bridge can operate normally while the battery is
charging. The battery charges up to 8.2 volts in a maximum of
2.2 hours, with a maximum power consumption of 16 watts
(during simultaneous charging and operation). The ES210
Bridge will auto-charge whether power is on or off (Section
3.2.1).
The wall-mounted power supply provides 12 volts at 2 amps
input current to simultaneously power and charge the ES210
Bridge.
Charge the battery at a maximum input current of 1.78 amps.
Do not exceed 30 volts on the Bridge’s 9-28V power supply.
For safety, the Bridge prevents the battery from charging when
the temperature is outside the acceptable charging range:
 32º–113ºF (0º–45ºC) when the Bridge is powered off
 23º–104º F (-5º–40ºC) when the Bridge is powered on
For maximum life, charge the battery at about 20º C (68º F).
2.1.2.3 Battery Storage and Longevity
For maximum life, store the battery, half charged, at about 20º
C (68º F).
Fully charged batteries lose less than 10% of their charge
when stored for six months at 73º F(23º C); less than 20%
when stored for three months at 113º F (45º C).
To prolong battery life:
 Charge the battery early and often. However, if is not used
for a long time, store it at a half charge level.
 Do not routinely "deep-cycle" the battery (frequently
discharge fully and recharge it).
 Keep the battery cool, ideally in a refrigerator. High
temperatures (as found in a closed car, for instance) cause
lithium-ion batteries to degrade much more rapidly than if
not so exposed. In harsh thermal environments, consider
removing the battery when it is not in use and storing it in a
cool place so that it is not affected by the heat.
 Do not freeze the battery. Most lithium ion battery
electrolytes freeze at approximately -40º F/C.
2.1.2.4 Replacing the Battery
If you need to obtain a replacement for the ES210 Bridge
battery, contact your Fortress Technologies representative.
1 Power the Bridge down by depressing the Power Off button
on the right side of the chassis. If external power is in use,
disconnect the Bridge from the power source.
