Q Is it safe to leave my trickle charge on full time?
I recently read in MCN about leaving a bike on a trickle charger to stop the battery sulphating. I have an Oxford Oximiser attached to my BMW F800GT that’s been switched on for four weeks and the state says the battery is ‘strong’. Do I leave it on, or should I switch it off from time to time while the bike is laid up? Adrian Bird, email
Answered by Chris Dabbs, MCN Trickle chargers such as your Oximiser are designed to assess the battery condition and apply the correct charge. So they can be left connected and turned on indefinitely to charge a modern gel or maintenance-free battery. If the battery is an older acid type with refill caps then it’s important to monitor the fluid levels as the battery will lose electrolyte over time. Modern sealed types do not suffer from fluid loss.
