P.S. Where are you getting your batteries? Some dealers are not diligent about properly filling and charging a new battery. This can cripple them before they get to your bike.
Indeed. Correct new battery commissioning is very important. Triumph publishes this procedure on all their technician training manuals for use by their dealers service departments:
Battery Commissioning Procedure
This procedure is designed to ensure that the battery is at its best when fitted to the motorcycle, and provide the best possible performance and reliability.
Failure to comply with this procedure may lead to reduced battery performance and/or shorten the life of the battery.
Warning! The electrolyte solution is SULPHURIC ACID. Ensure that you read all the warnings supplied with the battery and are familiar with the necessary safety precautions and remedial actions should spillage or contamination occur.
Read the instructions and warnings delivered with the battery!
Place the battery on a flat level surface and remove the sealing foil.
Remove the battery sealing strip from the electrolyte container (if applicable) and save for use later in this procedure. Do not break the seal on the electrolyte container.
Place the electrolyte container and adapter (if applicable) on the battery and fill the battery according to the manufacturers instructions.
After starting to fill the battery with electrolyte, allow the battery to stand for 30 minutes with the filling container in place.
Check that all of the electrolyte has drained from the container, do not remove container at this point. If the container has not completely drained, tap the sides of the container to start the electrolyte flowing again.
After all of the electrolyte has drained into the battery, allow the battery to stand with the electrolyte container in place, for a further 30 minutes for batteries 3Ah – 12Ah or 1 hour for batteries greater than 12Ah.
Remove the electrolyte container and adapter carefully, and dispose of immediately.
Fit the sealing caps to the battery according to the manufacturers instructions.
Measure the terminal voltage on the battery to assess the battery condition and charge the battery as necessary (see table of charging time) using a suitable charger (i.e. a charger with a suitably controlled charging current and appropriate cut off voltage.)
Charging current should be controlled to 10% of the nominal capacity (i.e. for a 10AH battery charging current I = 0.1 x 10 = 1Amp)
Table of charging time
Terminal Voltage....Charge Time......Cutoff Voltage
>12.8V............... 2 hour............ 14.5V
>12.7V............... 3 hours........... 14.5V
>12.6V............... 4 hours........... 14.5V
>12.5V............... 6 hours........... 14.5V
<12.5V............... 8-10 hours........ 14.5V
Disconnect the charger and allow the battery to stand for 1 hour before fitting
to the motorcycle.
Fit the battery to the motorcycle, positive (Red) lead first.
