MOST BATTERIES are situated beneath a bike's seat or petrol tank, so it's hardly surprising many get overlooked when it comes to routine maintenance.
When a battery becomes very discharged, it usually means the end of its life, so routine checks should be made on its condition.
Ideally, remove the battery from its holder before carrying out any work. Remember, batteries contain strong acid, which can be harmful if it comes into contact with your skin.
Check the acid level in your battery by placing it on a level surface. If the level's low then top up with de-ionised water before placing the battery on charge, using a car or motorcycle charger. Remember not to overfill, as acid will drain out the overflow pipe when you're on the move. Many moden batteries are sealed, so you won't be able to top them up.
Greasing your battery terminals before replacing it in the bike will help avoid corrosion. Just remember not to touch both terminals at the same time.
