New Battery Dead !!

this might sound a bit silly but did you double check the amperage of the new battery is at least as good as the old one?

I got a Westco battery and its been superb.....perhaps you got a dud one




FAQ's

How do I test my 12 Volt battery and charging system?


Following are three tests you can perform on your battery and charging system.


Static Battery Voltage Test

Prior to conducting this test, make sure the battery has not been recently charged. You must wait at least one hour after charging your battery to conduct this test.

Adjust voltmeter to DC volts (20 volt range).

Place voltmeter leads to the battery terminals. (positive to positive and negative to negative)


Read voltage and refer to the chart below.


State of Charge

12.80v ........................ 100% Charged

12.60v ........................ 100% Charged

12.40v ........................ 75% Charged

12.10v ........................ 50% Charged

11.90v ........................ 25% Charged

less than 11.80v .......... 0% Charged




Starting Load Test


Adjust voltmeter to DC volts (20 volt range).

Place voltmeter leads to the battery terminals. (positive to positive and negative to negative)

Watch the voltmeter as you start your motorcycle.

If the voltage drops below 9.5 volts, the battery has very low capacity and should be replaced.



Charging System Test


Adjust voltmeter to DC volts (20 volt range).

Place voltmeter leads to the battery terminals. (positive to positive and negative to negative)

Start your motorcycle.

Bring engine RPM's up to approximately 3,000

Compare the voltage reading to the specification in your owner's manual.
(Note: the voltage reading should be approx. 14.0 - 14.5 volts to properly charge an AGM battery.)

14ah but has it got the correct CCA....(cold cranking amps)

i've had similar battery woes
mine is a ytx12-bs thats all i know, shows 12.5v but wont turn the bike over more than once after a charge
its going back

dont mean to sound daft but if the old one works ok why waste the money on a new one:confused

cos i was having problems starting and was worried the sprag clutch might go, so my dealer recommended a new battery, the problem continued after fitting new battery until now (i hope) as it was loose connection on starter relay
battery is going back and 45 spondoolies are going back in my bank

Hi BB did those tests , ref CCA it was the correct model for the Mille so assume it to be correct .


Hi Pointer - to be honest think i was just being a bit belt and braces and read to many posts about these things eatng batterys so decided to upgrade now rather than wait as owner explained it was still on orginal batt !!but on reflection may as well just get money back for now . IT must be a dud but still baffled why it doesn't work with that many volts showing .

BB - where did you get yours from ?

had lots of problems with the battery on my vtr so i bought simple but cheap trickle charger of ebay for £13 so understand the worry when you get up in the morning :thumbup

Did you check the battery was wet? (had acid in it), bike batteries are shipped dry?

Got my battery from a small shop in Biggleswade.....:thumbup

Good news buddy
