Q. I have a Gardena reel lawn mower, electric with battery. I know it needs to be fully charged before re-use, like 24 hours, but should it be fully DIScharged before I re-charge?
By the way, the power adapter (a transformer type) was giving only 9 volts for a 12 v battery, so it would never hold a charge - had to buy a new one.

Answer
Always a good idea to fully discharge because of battery "memory".Your battery will loose its maximum charge if repeatedly recharged before being drained. The battery tends to remember the smaller charge.It can also cause the battery to loose its peak voltage more quickly.

How does the 12 volt battery in a riding lawn mower?
Q. charge during operation of the mower?
Answer
Your mower has a magneto that operates the electrical system and charges the battery. It is a very simple electrical system, compared to that on a car. For example, the magneto must be in operation for the lights to work. That way they don't drain the battery.
The main drain on your battery will be starting the engine. This electrical system has no voltage regulator, but there is almost no danger it will overcharge the battery. Under normal conditions, if you take care of it, a battery should last about two to three years, sometimes more. It is a good idea to use the headlights when you are mowing, especially if you are near a street or highway.
Under normal conditions there is very little drain on the battery. When storing the mower for the winter it is a good idea to disconnect the battery.
