8.4 V NiMH rechargeable battery, 9 V size.
– Disconnect test leads from all the terminals
when charging the battery.
– Ensure proper insertion of battery in the
multimeter, and follow the correct polarity.
– Upon initial use (or after a prolonged storage
period), the rechargeable battery may require
three to four charge/discharge cycles before
achieving maximum capacity. To discharge,
simply run the multimeter under the
rechargeable battery's power until it shuts
down or the low battery warning appears.
– The multimeter may indicate that charging is
complete after ten minutes when charging a
new rechargeable battery. This is a normal
phenomenon with rechargeable batteries.
Remove the rechargeable battery from the
device, reinsert it, and repeat the charging
procedure.
