Technical | How To / 2022 AK 500 With Tender Battery Not Starting After Charge
« on: January 04, 2026, 05:47:13 PM »
First time posting on the forum for my 2022 AK 500 that I've had for about 18 months. Last year, when I was away for the first time and not riding for about 8-10 days the battery became low (below 9-10v) and the bike wouldn't start...no engine noise just clicking. I used the tender for the first time, and it started right up. Months later, this situation happened a 2nd time when gone 6-7 days and I did a tender charge again with no problem. Then a 3rd time just last month over Christmas with a 6-day absence and it started after a charge; I successfully turned it on/over (to test it) but did not actually ride. 6 days later (after that), it wouldn't start again. After putting it on the tender it still won't start. When I turn the power on, dash panel shows 12.4 v, but after I try starting it (with engine noise/power trying to turn and lights on) it drops to 11.7 v. Do I keep charging it on the tender more even though the light (on it) is green? Does it need a jump from a more powerful battery starter, say from a tow truck? Or does it need a completely new battery itself since I assume this is the original? Again, there is def. more power showing on the dash, voltage and sound than the first time when it was just 'clicking' but it's not starting up.
Also, for context, I have always turned it to the RIGHT side to shut off the engine after each ride thinking that was OK. Just learned from reading in the forum that apparently, I needed to turn off power to the LEFT to get the red ring light to completely shut it off. Perhaps this has contributed to the issue?? Appreciate feedback on what's going on and my options to remedy. Thanks.
