Manual Soldering:
The terminal should be soldered at a point as far as possible from the spot-welds to the
battery.
With a soldering tool temperature of 350° C the soldering operation should be
completed within 5 seconds, with a tool temperature of 250° C the operation should be
completed within 10 seconds.
Fitting:
Check the polarity carefully. The style of battery employed on the PME 68-1B has two
connections at one end and a single connection at the other end. The board is fitted with
corresponding plated-through holes.
In general:
Solder should not be applied directly to the battery.
Do not stack batteries in contact with one another and take particular care to avoid
short circuits at all times.
Do not heat the battery
Do not incinerate
Do not attempt to charge the battery
No attempt should be made to open the battery or pierce the casing.
Batteries should be stored in a dry location at normal room temperature with minimal
temperature variations. Corrosion and loss of performance will result if stored in damp
or hot conditions.
Do not expose batteries to direct sunlight or rain.
Use a charge prevention diode if there is a possibility that a battery could receive a
charging current from a source of power. (The PME 68-1B has been fitted with charge
prevention diodes.)
The batteries should not be positioned close to other heat emitting components. (The
battery on the PME 68-1B has been positioned near the edge of the board at a location
well away from potentially hot components.)
To measure the battery voltage it is necessary to use a meter or measuring instrument
with an impedance or input impedance greater than 1M Ohm.
