  80% of lead-acid batteries fail prematurely due to the build-up of lead sulfate crystals on the battery plates. Over time, lead-acid batteries accumulate formations of lead-sulfate crystals on the lead plates. These crystals act as an insulator, gradually restricting the flow of electricity. Eventually these crystals will make batteries unusable. Our patented electronic device, the Battery Life Saver (BLS), handles the problem of lead sulfate build-up. Once connected to the batteries, the BLS generates a low frequency wave² through the batteries which dissolves the sulfate crystals (think of an Opera Singer breaking a wine glass).  

All about the Battery Life Saver


Using the BLS on your R.V.

You can use the BLS on the starter batteries as well as the house battery bank, only one BLS is needed per bank (most customers will rotate the BLS from bank to bank). To use the BLS, simply connect it to the main positive and main negative battery terminals. Once it is connected, use everything as normal, the batteries should be charged regularly. If the batteries in your R.V. are old, the BLS will gradually rejuvenate them to a good working condition. If your batteries are new, the BLS will keep them in a good condition and extend the life. In most cases, you can double or even triple the life of your batteries.
