Default State of the original three year old pack

Once or twice a year I take a look at my cart's battery packs. It is a good way to spot trends in the pack. When I took ownership of this 02 CC, it went through the same tests. The tests were performed on March 6, 2011. These tests are very formal, requiring my lab assistant Caly and a cold beverage....

My test:
  • Fully charge overnight.
  • Let cart sit for 10 hours after charge has completed
  • Take voltage readings of all cells
  • Take SG readings of all cells
  • Drive cart 10ish miles, taks voltage readings of each battery
  • Drive cart 10ish more miles, take voltage readings of each battery

First voltage check:
1-8.43, 2-8.46, 3-8.42, 4-8.41, 5-8.48, 6-8.42, pack-50.6
First SG readings:
Battery number 3 had readings of 1.17, 1.25, 1.25, 1.26
All the other batteries had cells around 1.25-1.26

After a 10 mile ride, pretty much full throttle:
1-8.32, 2-8.33, 3-8.30, 4-8.31, 5-8.37, 6-8.32, pack-49.9
I then did some stuff around the house for 45 minutes or so and headed out on another ride for 16 miles, so after a total of 26 miles my final voltage:
1-8.00, 2-8.00, 3-7.95, 4-8.01, 5-8.05, 6-8.01, pack-47.9
Pretty good pack based on my first impressions.
