The machine does
brake
The batteries do not last as
long as usual
The battery runs down too
rapidly during use, even
though it has been charged
with the correct procedure
and at the end of charging
it is evenly charged when
tested by a hydrometer.
The battery runs down too
rapidly during
charging with
electronic battery charger
is too fast and at the end
the battery provides the
correct voltage (about 2.14
V per element without
load), but appears to be
uniformly not charged
when tested with
hydrometer
At the end of charging with
the electronic battery
charger, the battery does
not provide the correct
voltage (about 2.14 V per
element without load) and
appears to be uniformly
not charged when tested
with a hydrometer
