Excalibur running down batteries too fast

[Reeseb]

I seem to have an issue with my Excalibur. Whether I use a lithium pack or the stock ML pack, I get the low battery squeal after about 2.5 hours. Was wondering if anyone else has experienced this or knows what could be causing it. Thanks.

How is the voltage when low bat comes on?

You might have a poor battery connection somewhere that creates a voltage drop.
Measure the current to see if it is normal. If so, measure the voltage right at the board to see if it is the same as across the battery.

I had same issue years ago when my batteries were old and worn out..I replaced the battery in the pod and it fixed my issue.. as previously mentioned checking the battery with a meter especially at full charge is a good idea..unfortunately I forget what they should read I think like 14.3 VDC or thereabouts...check both the battery and battery cable connector for corrosion also make sure the charging pins on the battery cable and charging cable aren’t pinched closed as this can contribute to a poor connection.. you can gently pry the gap open with a pocket knife if necessary... one of my batteries had a corroded wire inside the pod as moisture weeped into it from the hairline cracks in the pod...

Check the battery voltage to see if you are getting them fully charged. If i remember correctly they should be at around 14vdc when fully charged and should not give the low battery alarm until voltage drops down to around 9v.
