I replaced my OEM battery about a year ago. I would not trust yours at all, due to its age.
We had a LONG thread on batteries a while ago, you might look for it.
But, if you have a voltmeter, take a "resting voltage" reading of the battery after it's been sitting for several hours, preferably overnight. To do this properly, you want to open your hood the night before so the battery is exposed and you can get to it without opening doors which will activate electrical components.
If the resting voltage is in the neighborhood of 12.7 V or better, you are fully charged and I'd guess your battery is good. If it is below 12.4 V, I think your battery is on its last legs. Anything in between is grounds for a load test.
