The batteries must be properly maintained over the cold months and should be ‘trickle charged’ (charging at a similar rate as to its self-discharging, thus maintaining a full capacity battery) every 4–6 weeks to keep them in good condition. Don’t be tempted to leave a battery charger permanently connected as this can lead to plates in the battery warping and loss of performance.
Take home any gear which is easily detachable, remembering to Vaseline the plugs left exposed.
