How long could you do on a Misdemeanor Battery and running from the cops?

There's not enough information to determine an exact amount of time.

In California, if convicted of any felony, you potentially face one or more years in prison, plus fines; on any misdemeanor, you potentially face up to 12 months in jail, plus fines. Priors and strikes will add ?penalty ?enhancements? under the 3-Strikes rules. If this constitutes a probation or parole violation, factor those new violation charge[s] and old deferred sentence[s] in as well. He could go away for years on this if convicted. The charges actually filed by the prosecutor will determine how much ?time? and other penalties could potentially be imposed. You?ll learn the actual charge[s] and any enhancements filed and get copies of all the police reports and prosecutors? evidence when appearing for arraignment at the first court hearing. When charged with any crime, the proper questions are, can any evidence obtained in a test, search or confession be used against you, can you be convicted, and what can you do? Raise all appropriate defenses with whatever witnesses, evidence and sympathies are available for legal arguments, for evidence suppression or other motions, or for trial. If you don't know how to represent yourself effectively against an experienced prosecutor intending to convict, then hire an attorney who does, who will try to get a dismissal, charge reduction, diversion, program, or other decent outcome through plea bargain, or take it to trial if appropriate.

It will depend on what he was on felony probation for. If he is charged with a probation violation and is found to have committed the violation, he could be sentenced to do the time on his original felony charge. I strongly suggest that you contact an experienced criminal law attorney for a face-to-face consultation and give him/her all of the facts surrounding his arrest. He/she would then be in a better position to analyze his case and advise him of his options.

First of all, hearsay is good evidence, and judging from your BF's criminal record he probably likes to talk so chances are they have direct verbal evidence from him. Secondly, what the heck is he still doing living in a 3-strike state like California??!

The main problem may be the felony probation and the maximum for that crime may be what your boyfriend is facing.

Sounds like a weak case. The DA is probably going to try to get some time out of a plea deal if he has violent priors. However, if everything is actually hearsay, then he should just go to trial and force them to dismiss. He needs a lawyer right away.
