Replacement bow thruster batteries

[mlthomas]

I think we have tracked the bow thruster fault back to the pair of Exxide Maxxima 900dc batteries which seem to have lost their capacity (plenty of volts, no umph).
Any idea of suitable alternatives as these have failed just outside of their two year warranty! Need to be able to deliver a very high current for a short period

Hi, are you sure it is the batteries? With ours it was the solenoid. The contacts had become a little grubby/corroded. Cleaned them up and it is now working fine
