A high PT usually means that there is serious liver damage or cirrhosis. Other things to know: Some patients take a drug called Coumadin (warfarin), which elevates the PT for the purpose of thinning the blood. This is not related to having liver disease because it is the Coumadin causing the PT to be high.
A battery backup, or uninterruptible power supply (UPS), is primarily used to provide a backup power source to important desktop computer hardware components.
And you should know that the battery acts as a power conditioner itself - all the power from the power supply goes through the battery, if it's in place. Actually, a power conditioner, or UPS, is nothing more than a big battery with an alarm on it. So. leave the battery in.
