Just bought one of these:

As usual, the manual turns out to be a single sheet of paper with what I feel are inadequate/unclear instructions. Anyway, I'm wondering what the best way to maintain this unit is after the initial 38 hr charge which it's currently in the middle of.
The supplied leaflet only states that after the first charge a full charge takes c. 34 hrs but how do I know if a full charge is required? The battery status indicator notes simply state that if the indicator shows a reading of 13-15v it's ready to use. If it shows 12v it should be charged ASAP and if it shows less than 12v it should be charged immediately. I have no idea how accurate the status indicator is however, and I'd have thought the amount of charge time the unit requires would depend on how much it's been used but there's no mention of this and I obviously don't want to damage the unit by overcharging it. For example, is it simply a case of checking the battery status indicator periodically and turning off the unit when the level shows 15v, even if that's taken less than 34 hours?
