It is truly enjoyable to have your own an RV which is equipped conveniently inside, but how to test a deep cycle battery to make sure it is working properly.
One thing you should know is that a travel trailer largely depends on the system function which has to work on twelve volts. To be honest, I rarely test out these 12 – volt batteries of the RV house or known as deep cycle ones, so they often stopped working properly. You may imagine how amazing the experiences were, and then your RV suddenly stopped functioning. I sometimes felt angry a bit and actually lost at such moment.
For this reason, I made a decision to check the deep cycle batteries regularly. Because in fact, even the best deep cycle battery for RV is able to capacity while it sits for a longer time. In particular, before you plan an adventure, it is critical to do the test of the deep cycle batteries to see whether they can operate well or should be replaced.
And in this post, I hope that some information I would like to share with you on how to test a deep cycle battery would help you a lot. In my opinion, it is necessary for you to look after your batteries, and in return, they also will help you in the long run.
How to Test a Deep Cycle Battery Step by Step
Gather the Necessary Supplies
You may wonder where to start to be able to know how to test a deep cycle battery. In my opinion, first of all, you need to prepare all the necessary supplies. In case your battery is non – sealed, I strongly suggest that you make use of a compensated hydrometer with high quality. As usual, these supplies can be bought at an auto parts store with the price ranging from $5 to $20.
You may know that to determine the state of charge, a hydrometer which is a kind of float type device will be used to measure the electrolyte’s specific gravity in each cell. This is considered an extremely accurate method of determining the state of charge of the battery as well as its dead or weak cells.
In order to adjust the electrical or charging systems or in case you are using a sealed battery, my advice is that you need to prepare a digital voltmeter with the least accuracy level of 0.5 percent. You can purchase this device at any electronics store such as Radio Shack with the price ranging from $20 to $50.
Although you can use analog voltmeters, their accuracy is not highly appreciated for the measurement of millivolt differences of the charging system’s output or in the state of charge of battery. It’s up to you to decide whether to buy a battery load test that you can buy at the auto parts stores with $
