I would be care because even if it can be charged, some of them will lose it quickly. I tender mine, and have throughout the colder months around April and May (colder than the norm here in PA) and now it just died in perfect moto weather. So even though I know I can tender and charge it again I won't risk riding it to the city then having it die on me because it can't hold a charge. I am not sure yet if it's the alarm system I have installed causing the drain or if it's the battery. My guess is it's a little of both in my scenario

 

UDPATE: The madness is not over. I took the old charged battery and got it started for a moment to do the voltage testing. It held at 14+ at idle and when i revved it would go up slightly but never drop under 14 so I know it is not the stator. Then I did the series test for current. Hooked everything up and tried starting and it wouldnt fire. So i was fed up and got the new battery. well my miseries didnt end there. the darn thing which i cross-referenced at Batteries Plus was slightly larger LxW and wouldnt freakin fit in the tray. i learned my lesson. I should have just went with the stock Yusa brand. I live in an apt building so i self-storage the bike. had to pop start it down a hill in 3rd and it fired.

Next step is to check the rectifier. Where is this located on the f4i?

Wouldn't the bike die if the stator was shot and running off the battery. I pop started it and let it sit there and rode it fine back to the garage.

 

what is the average life of a battery. my bike is a 2001 so the stock battery has lasted over 8 years till now. im basically down to the rectifier and battery. the bike runs fine and does not stall once started.

 

If a very weak battery comes up to full charge in 5mins, then its dead, final, forget. It simply has lost its ability to store charge. With a bad stator or rectifier, you won't be able to pop start on a dead battery.

I parked my bike for about two months and the battery simply died. It was a stock battery and had never missed a beat. But it had drained so low during the period that there was nothing charging could do.

 

mine was stored during the winter for an excess of 4 months without charging or starting.

 

so does anyone know if these everstart (walmart batteries) that you fill yourself are good or not?

they're half the price...and Im unemployed and really want to avoid having to spend twice as much on a battery.

 

im done with buying cheap batteries. i spent gas to go far to get it for $79.99 and the damn thing didn't fit then had to return it. I'm just getting the YTZ10s for $114.

 

I bought the wrong size too haha (too tall). I filled and charged two batteries over the past 24 hours, both of which I successfully returned somehow. Finally I got the right size, drove in my car, so I could bring it home and charge it instead of riding my moto to the store to only find out it isn't gonna start my bike (only made that mistake one time ).

The one that was too big did however start my bike right up. I am having a guy rip out the alarm that's currently installed just in case that's part of the reason the bike has been leaking power (which I assume it is because the battery was only a couple years old and is totally fcuked).

Hopefully after this I can be like most people and just start and stop my bike as needed with no worries about it not starting.

The irony is my 1995 ZX-6 started up after two or three tries after sitting for weeks in 30+ degree weather!
