I found a 36 volt cordless mower on a local for sale site for $25 with a dead battery. The mower is in excellent condition.
The battery was left on the charger for a couple years.
Not a drop of electrolyte in the cells when I checked them.

Having survived the 30 meter drop I decide to fly it again!
With the canopy removed and the camera mounted on the battery I put this bird through its paces once again.
Stay tuned because I am not finished with this helicopter yet!

Every 12,000 miles (20,000 KM) is a good interval to change out the cabin filter.
I tend to change both the cabin air filter and the engine air filter at the same time.
It is a simple way to keep your vehicle in top condition.
