Subject: problems with maintenance free battery


Hello fellow atics,

When you haven't used your @ for a long while (what a shame, but it happens)
don't despair if your expensive battery seems to have a loss of capacity.
These maintenance free batteries will not charge very well inside the bike
or with a usual battery charger if they haven't been used for a long time.
To 'revive' your battery, just take it out of the bike and try to get an
adjustable power supply from 0-30 Volt and increase the voltage until you
have a charge current of about 1-2 Amps (charging voltage will be between 16
and 24 Volt)
After a few hours, your battery will become warm, indicating that it is
charged and as good as a new one.
I did the following test before and after the 'supercharging':

after 48h charging at 14V:
Nominal battery voltage: 12.42V
Voltage with charge of a 55 Watt H4 lamp: 12.02V
After 1 minute: 10.51V
After 2 minutes: 9.58V

after 'supercharging':
Nominal battery voltage: 12.52V
Voltage with charge of a 55 Watt H4 lamp: 12.21V
After 1 minute: 12.11V
After 2 minutes: 12.10V

Quite a difference I think!
BTW: A lot of Honda dealers have a 'Honda made' special high voltage charger
to cope with these problems.

Greetings,
Freddy
