I ordered the 6V 2100mAh battery pack and 3 days later I received it. It matched the old battery with the exception that the red and black wire is longer, but I was able to tuck in the excess wire without difficulties. It took a few hours to fully charge and the low battery message disappeared. The message reappeared on Monday, May 27th but disappeared and I have no longer received any low battery messages. I installed the battery Sunday, May 26th. At the present time, I am satisfied with the battery.
