Oh and one other thing.
If you want a good discharger that doesn't burn your battery, is inexpensive and easy to find, go to Canadian Tire and buy a 12v automotive backup light and connect it to your battery to discharge it. The draw of the light is a load that is long and does not burn the battery and the light is visible so you know when its done. It also leaves the necessary residual charge in the battery - you should never completely discharge a battery, that destroys the chemistry. Total cost should not exceed $5. So buying a charger for the sole purpose of getting a 10A discharge circuit (which is TOO HIGH IMHO) is a waste of money.
