G'day All. I charged up a new lead acid battery this evening, which I intend to put in the bike (the Bullet) tomorrow. When placing the charger clamps on I was careful of course to match the charger clamps and battery terminals. I just went out to remove the clamps and... ...I clearly wasn't that careful, because I'd fitted the charger's positive clamp to the battery's negative terminal and vice versa! The battery sparked when I first fitted the terminal which I thought odd, but I know nothing of such technical things. I had the charger (2.7A car charger) on it for six hours and took it off because nothing was happening and I need to go to bed (I thought it odd that it was taking so long when last time it took 20 minutes on this charger to charge a new battery - the 'power' light was on the whole time but the 'full' light never came on. The battery was cold throughout). Using a multimeter test the proper way round (positive to positive, negative to negative), I get 12.25V on the battery; and if I reverse the test (positive to negative on the multimeter to the battery) I get minus 12.25. The battery charger when disconnected now shows the 'full' light permanently and sparks when I touch its connectors to the battery either way, correctly or in reverse. So what does this all mean? What is the consequence? Do I simply hook the battery up as normal tomorrow? I'm guessing it ($57) is fine and maybe the charger ($10) is now cactus?
