Knackered Battery??
« on: »
Hi All and a happy new year etc,

The sun was out this Wednesday and so my mate came round for us to go on a ride out..
I came to start my bike and there was nothing but a loud click from under the seat (Solenoid)..
Put a volt meter across the terminals and it read 12.4 volts which dropped to 4 volts when the starter button was pressed.
I should add that the lights on the speedo go totally out when the starter butten is pressed
The Battery thats in it is a MOTOBATT MBT14B4 and reading the info on the Battery its rated at 175CCA !!
I have heard mixed reviews about MOTOBATT
I have had no symptoms of a sluggish Battery previously.. I do NOT have access to mains power where the bike is kept and so NO it isnt hooked up to a charger, but then neither were any of my previous 8 bikes over the past 4 years!
Last night the temperature was below freezing, so I am wondering if that tipped the battery over the edge..
Car lives outside and starts first time every time..

I have my eye on a YUASA YTX14H-BS which is a high capacity version of the standard OEM battery. Its rated at 240CCA

Just before I splash out on the YUASA can anyone confirm it sounds like a dead Battery please?

Thanks in advance

Sounds like a bad battery, they sometimes have full voltage but no amps. Could also be poor contact at the battery poles. Clean and re-tighten to test.

Interesting as i have a MOTOBATT on the Stage 3 i picked up last year and that has some strange starting issues. The previous owner said it was new but after a couple of starts it struggles until it's had a full Optimate top-up. I haven't had time to look into it properly yet but maybe a new battery is on the cards.

Thanks to you both for your replies..
I dont think it would have hurt if Yamaha had made the space for the battery a bigger one so we could fit a battery more up to the job of turning the monster V twin over on cold days..
