I purchase a Mega Crank MTX-30L AGM Maintenance Free Battery back in Nov. of 2016, starting to have some starting problems. Just read to thread by Jery about rebuilding the starter. I, too, use mine around the house with many starts. Just wondering if the life of the battery is about up or maybe should be looking at the rebuild brush kit. Original battery last about 2 1/2 years, similar to this one. Is this about normal? Did do a lot of plowing this year (winch use). Going to start with a load test on the battery. Looking for opinions before I start spending money.
