1) Testing the battery:
Some maintenance free batteries do not have a charge indicator at the top. To find the state of charge measure the open circuit voltage. Measuring terminal voltage with a digital voltmeter usually makes this test. A battery with a OCV of 12.40 volts is charged enough for testing, if the voltage is less than 12.40 volts then battery needs to be charged.

Hey, very nice site. I came across this on Google, and I am stoked that I did. I will definitely be coming back here more often. Wish I could add to the conversation and bring a bit more to the table, but am just taking in as much info as I can at the moment. Thanks for sharing.
