The battery in the Eclipse will last 5-10 years. If your unit is old enough you might want to consider investing in a new battery. But, battery effects only occur when you power down.
If the problem you have occurs without power-down, it is probably not the battery. Most likely you are confusing yourself. But, if you are convinced this is not the case, and it is a hardware problem, you should contact support@eventide.com, giving all your details.
