BLS For RV Batteries

Batteries in a RV can be expensive, difficult to replace, and at times, unreliable.  Most RV’s have house batteries along with starter batteries. The house battery bank is usually made up of 4 to 6 deep cycle batteries that are used to run common electronics when not connected to AC power.  The average life of good quality deep cycle battery’s is 3 years, with each battery costing between $120 and $200 per battery.

80 % of lead-acid batteries fail prematurely due to the build-up of lead sulfate crystals on the battery plates. This build-up makes batteries unusable at approximately 1/3 of their natural life.  The Battery Life Saver (BLS) handles this problem.  Using U.S. Patented technology, the BLS sends a frequency signal that matches the resonant frequency of the sulfate crystals (think of an opera singer breaking a wine glass).  This dissolves the sulfate crystals rejuvenating both the electrolyte and the lead plates.

The BLS will rejuvenated old “dead” lead-acid batteries and extend the life of new or good working batteries. We have records of the BLS tripling normal battery life.  The BLS will allow for shorter charge times, longer runs times, lower water consumption and most importantly, longer battery life.

 Advantages of using the BLS:

  • More than a 99% Customer Satisfaction Rate
  • Easy to use, attach it and forget it.
  • No chemicals needed, it is an external device.
  • By constantly dissolving sulfate crystals, the BLS can double and sometimes triple battery life. This can save you $1000’s over time and you will be helping to save the environment from harmful battery waste.
  • Rejuvenates old batteries.
  • Only one BLS is needed per battery system.
  • Reverse polarity protected
  • Built to last, sturdy and elements resistant
  • Easy Do it Yourself Instructions, if you can connect jumper cables you can connect the BLS!

BLS Models:



For 12 and 24 volt battery systems and vehicles with multiple batteries. Most commonly used on RV’s and marine applications. Can be installed permanently on a battery system. The system should be charged regularly. Similar to the BLS-12/24B, but comes with 3/8″ eye rings for attachment to the battery terminals.



Designed for a 24 volt battery or battery bank. Can be instailled permanently to keep the batteries in optimal condition and extend battery life. Should be installed on new or good working batteries (use the BLS-12/24 to rejuvenate old batteries). Equipped with a low voltage cutoff.


12 Volt BatterySolver Package

Storage solution for 12 volt batteries. It is also an automatic solution to rejuvenate old “dead” batteries. Connect the BLS and the charger to the battery . Plug the charger into the timer, and set the timer to turn on once a day for 4 hours. This will rejuvenate your battery and keep it in optimal condition. Includes BLS-12/24B, the VEC080(12 volt, 2 amp Float Charger) and an indoor timer.


I am an RV owner. I want to tell you that the Battery Life Saver brought back my $225 battery that was in very bad shape. It took a while but it’s still working great. It makes me very happy

I wanted to call and give you a report on your Battery Life Saver. I was very skeptical when I ordered the BLS from you, knowing that there was a money back guarantee, I decided to give it a try.
I have 6 x 6 volt batteries in my R.V., all with very poor specific gravity readings. After using the BLS for a month and a half, all the batteries are now reading close to new batteries. I am very happy with the results and I will try to spread the word as much as I can. Thank you.

I’m using the desulfator on the four 6-volt golf batteries in my motorhome as well as the two 12-volt
batteries for starting. I’ve had the motorhome for a year and a half and don’t know how old the batteries
are. When adding distilled water to the house (golf) batteries, I noticed that the plates where 100% clean.
I hope to make them last as long as possible. Thank you.
