Charging Motorcycle Batteries
A fully-charged 12-volt battery should measure about 12.6 – 13.5 volts between terminals depending upon its chemistry.
12-volt batteries motorcycle batteries supply useful energy only through a limited range — from over 14 volts (when fully charged and unrested) down to 10.5 volts in use/under load (when lights dim, your motorcycle is hard to start). No 12-volt battery will remain at over 14 volts for more than seconds unless it’s being charged. The lowest limit is 10.5 volts (used in testing) and obviously unsatisfactory in practical use.
If your battery is a flooded lead acid (with caps) check the fluid levels on each cell before charging. If any cell is low, carefully fill it to the minimum level using distilled water. Use only distilled water.
When charging conventional flooded lead acid batteries, loosen vent caps and ventilate charging area. A buildup of hydrogen and oxygen in the battery or in the charging area can create an explosion hazard.
If the battery feels hot to the touch during charging, STOP. Allow the battery to cool before charging again. Heat damages the plates, and a battery that is too hot can explode.

Properly connect the charger to the battery: positive (RED) charger lead to positive battery post and negative (BLACK) charger lead to negative battery post. Unplug the charger or turn it off before you disconnect the leads, which will cut down on the chance of the clamps arcing on the terminals.
ALWAYS use a Motorcycle/Trickle Charger when charging Motorcycle Batteries. A Motorcycle charger supplies NO MORE than 7.5 Amps during the charging process. Make sure your charger is the same voltage (6 Volt or 12 Volt) as the battery you are charging.

Charge for a full 8-12 hours.

NOTE: If your battery is HOT – STOP. You’re doing it wrong or your battery is damaged.
If your battery SWELLS – STOP. You’re doing it wrong or your battery is damaged.
If your battery is SMOKING – STOP. You’re doing it wrong.

    Received a free charge at O’Reilly’s and when I picked it up it felt hot. Before I got to the door the bottom of the battery was almost too hot to touch. I got it to my cycle and still my bike wouldnt turn over, so I think it to be a starter problem. Now,at home with the battery, it is cool to the touch. Could it have exploded earlier? And shouldnt the tech know about hot batteries and advise customers to that effect?

    A motorcycle battery should NEVER be charged on an Automotive charger… my guess is, that’s what he used.
    Batteries, however, do get warm during charge… it just part of the process.
