Another.... do I need to replace my battery?
So my battery died a couple of months ago when I leaving to go home from work. It was coldish out (~40*f) and I had my HIDs on when starting the bike, so I thought it was that. I was able to jump it but it happened again the following week. I had been doing sporadic testing of the battery, and yesterday I finally bought a cheap multimeter.
These were my results:
13.5 volts when fully charged by battery tender.
12.5 v under full load (lights, not running)
14.5 v with engine running.
About 30 seconds (maybe less) of starter motor going (engine not running) before the battery dies and the solenoid switch starts clicking (does it have a solenoid?). Voltage dropped from sub 11 v to almost nothing. Also it took only about 30 minutes to recharge that dead battery to full using the battery tender.
It looks like I need a new battery, but I guess I need some affirmation before I drop $130 for a Shorai battery.
Thanks in advance.
