The charging pattern should however be as follows with lead acid batteries! Always charge your batteries as soon as you can. Don't wait after a ride no matter how long or short your ride is. Lead Acid batteries must never be left in a discharged state even slightly. They will loose charge if left sitting. Charge at least every week if not used. Keeping lead acid batteries at full charge will prolong life and stop sulphation on the plates. Overcharging will kill them dead!
