Have I completely screwed my batteries?

Hubadub · 10-18-2011, 08:49 PM

I have a 2003 or 2004 EZGO TXT. The other night I accidentally left the lights on all night during charging. The batteries were weak, so I added water (the batteries were not completely dry, but they were low) and then I cleaned the terminals with a wire brush and generously added some anti corrosion grease to all the terminals prior to reconnecting all the cables. Directly afterwards, the battery meter showed full, I charged with the normal charger overnight and my cart barely made it out of the garage and died at the tee box 50 feet away. I then attempted to charge the batteries with a 12 volt car charger, charging two batteries at a time. The result was zero improvement. The batteries are the originals, but the cart was barely used and in great shape when I bought it 6 months ago. Since then, I've driven the hell out of it on the golf course and been fairly diligent on monthly maintenance to the batteries. What's my next step?

First, let's determine what year the thing is. Please supply the serial number and/or manufacturing code number.

Second, please supply digital voltage readings of EACH battery.

Third, if these are Trojan batteries there will be a code stamped into each negative battery terminal. Supply that code.

6.37 is a fully charged battery, you have only 1 that qualifies.

27 is on negative terminals

Should be a letter and a number, but you probably have 2007 batteries

My gut tells me the cells have had it, but hydrometer readings may confirm this.

May be an L7 .... anyway, recharge em.... and test again in the morning

Hubadub · 10-18-2011, 09:39 PM

I appreciate the input. How do I get a hydrometer reading?

Hubadub · 10-18-2011, 09:41 PM

Sorry wrong number on the batteries....L2 is on the negative terminals.

rib33024 · 10-18-2011, 09:42 PM

Are you sure about that L2 ??

How many hours was the batteries off the charger, before you took the readings that you posted??

scottyb · 10-18-2011, 09:44 PM

L2

Congratulations, you or somebody has gotten 9 yrs use out of your batteries, they are way beyond the normal replacement age...... it's time for new ones.

2002 batteries. Don't waste anymore effort, they are spent. Time for new ones. They have served the cart very well for 8 years.
