132 Keysight 53150A/151A/152A Operating Guide
Precautions
Observe the following precautions when handling and charging the batteries:
– Do not attempt to use or charge the batteries when they are exposed to
temperatures below –10º C (15º F) or above 40º C (105º F). (Most batteries of
this type have an internal safety device that prevents them from operating
outside of this temperature range.)
– Charge the batteries only with a charger intended for this type of battery or
inside the Counter.
– Do not allow the battery terminals to contact any conductive surfaces.
– Avoid discharging the batteries completely.
– Recharge the batteries as soon as possible after use.
– Handle the batteries carefully to avoid internal damage and/or damage to the
casings. Do not drop or throw the batteries or otherwise expose them to strong
physical shock.
– Do not incinerate the batteries or subject them to extremely high
temperatures.
