The EcoTech Battery Backup that I have is probably around five - six years old. What is the expected lifespan of these batteries? It still powers my MP-40 when the power is removed, but I am not sure how long it will run now before it dies. I want to be able to depend on it for extended periods, if needed. Did I read at one time that these batteries could be sent in for refurbishing? Thanks..
