Hi,
i am very sure that the batterys are dead. APC recommends to change the batterys every 3 to 5 years. I'd change them every 3 years to be sure. Its very unlikely that your 6 year old packs are still fully functional. I had the same symptoms at a customers APC (3000VA) and the battery packs were dead. Try to locate the packs on ebay, can save quite a bunch of money (but beware of low quality packs).
