After 7 years my battery went bad. One online supplier reccomended replacing the rectifier when changing the battery. I've never heard such a thing? It's $39, should I be concerned , what do you think?

If it isn't broken, don't fix it. The charging circuit on my 30 year old riding mower still works just fine. Unless the battery shorted out and overloaded it, it's probably fine.
Okay, I've never heard that as routine procedure. I too have a 22 yr old mower that is on its 5th battery never changing rectifier. I have not checked the old battery for a short. I'll do that.
Thanks

The rectifier is probably just a diode that can be checked with a multimeter. It is likely fine but if it ever does go bad, a diode is nowhere near $39 (closer to $1 + S/H) if you DIY replace it, with some soldering or crimping to do so.
Crank it up and put a voltmeter on the battery to see what it's doing. The B&S on my JD L100 runs at 14.2v . I put a cheap volt meter on it as it didn't come with a amp gauge like my Craftsman 14hp. . At least I know now if system is charging.
So yeah, the battery bit the dust. I can't complain, 7 years that's good life. I did not replace the rectifier, just the battery. All good, beware of advice from someone who can profit from following their advice.
