A few months ago I bought a used 2001 Suzuki Katana 600 with about 11,000 miles on it. I rode it without any issues for the first month or so. After that I started having occasional issues with starting it up. The first few times button start would not work instantly. I would have to re-try a couple times before the motorbike started up. Then a couple times button start did not work even after a few attempts. Push starting, however, worked. Note that in between these isolated incidents button start would work normally -- that is, at the first attempt. Finally, a couple of days ago, after not h

If the voltage was 10.5V that means the battery was completely empty, 0%. You should never let your battery go that low, several such discharges damage it irreversibly. I assume it is a lead-acid battery? Best never let it go below 12V (I mean voltage measured after the battery has been at rest - not powering anything, nor charged - for a few hours). If you discharged your battery that low, 5 hours is nowhere near enough to charge it, it will take at least 24 hours to charge it, if not more. Charge it until the voltage measured on the battery while it is being charged is at least 14.4V, and then a few hours more at that voltage (try to keep it constant, decrease the current if needed). Charge it with a 0.1C current (with current in amperes of 1/10 of the battery capacity in Ah, so for a 45Ah battery that would be 4.5A), or lower. Fast charging with higher amperage only gives surface charge, which will be gone quickly under load. After charging it completely you might try charging it wi
