Why does it turn off after 10 min   then when I turn it back on  it shuts off after about 2 min. I charged the battery last weekend when I put it away could this be the problem I should have charged it again last night

Would you have a multimeter to test your battery voltage before and after charging it? Maybe battery is bad, charger bad or possibly a loose connection somewhere?

It is only a week old
I can check the charging system when I get home    thanx for the info     would the battery loose charge sitting over a week

Voltage on battery b4 charging was 11.47.  that should be enough to run it ??

[tbern]

Battery could lose charge over a week if there is a bad cell in it or possibly some kind short in the system or a errant power draw.  11.47 volts is pretty low, should be closer to 12.8 with a fully charged good battery.

[wcbarkerf]

I will charge it and check it every couple of days. How long should it hold a charge?

[wcbarkerf]

battery reads 13.87 after charge

[tbern]

Just guessing the 13.87 reading was right after you removed your charger? Let the battery rest for at least 12 hours and check the voltage. At least it's a good sign your battery was showing the high reading after charging and not dropping the volts reading immediately after removing it from the charger.    I would think you could try hooking up your camera now and see what happens.  Do another volt  reading right before you turn on your camera and if you can , take readings from the battery while the camera is on.

After 2 days it reads 13.14v

[tbern]

Ok, little higher then what it should read but could be your multimeter is off too. So now hook up your camera and see what happens. Again if you can monitor your battery's  voltage while your camera is on, that would be helpful.

[wcbarkerf]

Day 3  reads 13.13

[tbern]

Again, time to hook up your camera and see what happens. Hopefully it will be good to go!

[tbern]

Did you give your camera a try?

[wcbarkerf]

tried it today all ok.   must of lost charge over the week when I didn't use it.
thanx for the info and help

Good to hear!
