4 years is generous.....I run with Trojan T-875 batteries and into the 3rd year I can notice a definite decline in power and the need for much more maintenance. Second set of T 875 batteries and I can just squeze 3 years out of them with out having worries.\
Wth 09 batteries.....I would say it is very likely you need new batteries ! Oh and changing only one or 2 batteries that read ow on the hydrometer will not be the answer...save yourself some trouble and just replace them all at once.
