First check the battery voltage using a multi-meter set to DC and volt range if reading is below 12V battery has probably one dead cell get a new one, if between 12v and 13V battery should be OK to charge. Remove battery undo negative lead first then positive. Please do not use a car charger or any other charging device that has an output greater that 1 Amp you will fry the battery. Charge the battery for as long as possible. Recheck volts across the battery if above 13V refit battery connect positive lead first then negative.
Start your engine, when warmed up check the voltage across the battery terminals it should be well above 13 volts. Increase the revs and watch the meter the voltage should increase to about 14.5 volts. This shows the battery is being charged. Please remember batteries on bikes only last a few years and short rides do not put enough charge in your battery. Buying and using a motorcycle Smart charger does help. I use a CTEK XS 0.8 12V Motorbike Battery Smart Charger & Conditioner. You get a small wiring harness that fits to the battery with a rubber connector that connects to the chargers plug. This unit will help to keep the charge in the battery topped up.
Access to your battery is likely under your seat. Remove the one or two bolts that hold the rear of the seat to the motorcycle and lift. When you find the battery, remove the cover, if any. Connect the red lead from the charger to the + post of the battery and the black lead from the charger to the - post of the battery. I wouldn't use anymore than a 2 amp regulated charger for this and I would not keep it on indefinitely. Couple days on ... couple days off is what I would do.
If you remove the seat and the battery cover, you can connect the battery charger positive lead directly to the positive battery terminal. Or, you can connect it to the battery connection at the starter, whichever is easiest to get to. Connect the negatve charger clamp to either the negative battery post or any good ground on the engine or frame of the bike. Once connected, turn the charger on with a 2-amp per hour charge rate.
You can charge the battery without removing the battery. Find the large cable that comes from the battery where it connects to the starter. Connect you positive charger clamp there. Connect the negative charger clamp to any good frame ground on the bike. You can charge you battery using this method provided you battery charger clamps are not too big.
If you can't do this, you'll have to take the seat off the bike, remove the battery hold down strap, and then move the battery outwards so you can disconnect the negative battery cable.
To charge battery, use a trickle charger at 2 amp. Batteries usually only last about 3 years, so if battery is at that age it probably needs replaced. (Replaced my battery with a lawn mower battery that matched the original battery size.) I would try to get a charge on the battery before replacing it. Replacing the battery could be expensive. Battery could also be low on zinc, water, or acid.
Yes, you can charge the battery without removing the seat but you must be able to get to the large cable connection on you starter. Connect the positive lead to this large connection and the negative lead to the engine at any convenient location.
The best thing to do is purchase one of the "Smart Chargers". They come with a "pigtail" that has a quick plug on it. Remove the seat and install the pigtail on your battery then reinstall the seat with the pigtail hanging out in a very inconspicious place. When you finish a ride, simply plug the pigtail to the charger. You'll always have a "hot" battery and your battery life will be greatly extended.
WELL BATTERY IS USELY UNDER SEAT OR SIDE COVER SLOW CHARG IS BEST IF YOU HAVE CHARGER ALL YOU DO IS HOOK IT UP POS TO POS AND NEG TO NEG AND IF ITS SEVICEABLE YOU MAY MAKE SHERE IT TOP WITH LITTLE DISTILLED WATER BE FOR CHARGING BUT MAKE SHERE YOU DO NOT LET THING SPARK AROUND BATTERY CAN CATCH FIRE HOPE THIS HELPS
