One of the reasons why a lot of people have not keyed into the solar and inverter power revolution is the challenges most solar and inverter power users have with batterries.
Before you condemn your battery, it is important to confirm if actually the battery is bad.
Also before you decide to pay for a battery, (most especially if it is a faily used battery, you must confirm the state of health of the battery).
It is not enough to simply use your regular volt meter to test if the battery voltage is up to 12volts. It’s not enough and advisable to just short circuit the positive and negative terminals of the battery and observe how intense the spark appears (shortcircuiting your battery is bad and can damage your battery).
To properly ascertain the actual state of health and state of charge of your battery, you need a very good battery tester.
A battery tester or battery meter is a specialised device specifically made for the proper testing of baterries. You can use it to test both your car battery and your inverter or solar power battery.
There are different types of battery tester. The analogue battery tester and the digital battery tester.
The analogue battery tester makes use of a heating element to properly and accurately ascertain the abilty of your battery to power your equipment are desired. The analogue battery tester will give you feedback as to the voltage off your battery and if your battery is good or bad or simply needs charging.
The digital battery tester is a more sophisticated electronic device that makes use of algorithms to calculate and give you feedback as to the state of health of your battery, state of charge of your battery, cold crankamperage of your battery, etc.
The digital battery tester also tells you if your battery is good, bad, or needs charging. The digital battery tester will also show you the percentage of your battery. Somedigital battery testing device have ability to also print reports.
When choosing a digital battery tester make sure you take one that has reverse polarity protection. Make sure you choose one that has the ability to give you a lot of information about your battery. The more features it has, the better for you.
