The instruction manual states that the LED light will flash while I am using it, to indicate that the battery needs to be recharged. So, I was attempting to recharge the battery before this happens, so that I don't run out while I am away from home. I've used this for about a day so far, powered off the battery and hooked it up to recharge. When I did so, the LED on the charger was a solid green and not red (which is supposed to indicate that it is charging). So does this mean that the charger will not charge the battery at all, until it flashes on and off? This doesn't seem right. I would want to be able to "top off" the battery to full, instead of having to wait until it is almost completely drained and then having to charge it up for 3-4 hours. Any help on this would be greatly appreciated, as I would hate to run out of battery life while I am out for the night.
