Hello and thanks for using JustAnswer.I will try my best to help you with your question.
Yes, it could be the battery. You can have the proper voltage, but your engine needs CCA (Cold Cranking Amps) to crank the engine over by the starter. I think your battery should be rated at either 650CCA or 750CCA. Have the battery properly load tested to make sure. Any good auto parts store can do this for you for free.
