What Is The BLS?

What is the Battery Life Saver™ electronic device (BLS)?

An electronic device that brings old & weak batteries back to life, restores functioning batteries to a like new condition, and extends battery life by keeping batteries from losing capacity and life due to the main cause of battery failure: the buildup of lead sulfate. There are different models for different voltage systems.

What type of batteries will the BLS work for?

The BLS will work on any lead acid battery, including GEL and AGM batteries. Lead Acid batteries are commonly used in cars, trucks, RV’s, boats, forklifts, solar/wind systems, floor sweepers, and much much more. Click Here to find the BLS model that suites your needs…

Understanding Batteries & the Battery Life Saver electronic device.

To understand the technology behind the BLS, we must first understand how a battery works.

How a Battery Works

In a normal battery we have three basic elements: one plate made of lead, an electrolyte of sulfuric acid and another plate made of lead oxide. When the battery is discharged, the sulfuric acid in the electrolyte reacts with the lead and lead oxide releasing electricity, forming lead sulfate. This leaves a watery electrolyte solution. When a battery is completely discharged, what is left is lead sulfate and water. When you recharge the battery, the electrical current causes the lead sulfate to break apart. This returns the system to the original elements of lead and lead oxide on the plates and sulfuric acid in the electrolyte, for the most part.

What’s the problem? Why do batteries fail?

When the battery is recharged, a small amount of lead sulfate maintains its sulfate configuration (sulfate crystal).

These sulfates crystals cannot be reconverted using a regular electric current. Every time the battery is discharged, more of these crystals are produced and the electrolyte solution becomes more watery. Like layers of snow on a garden they continue to accumulate until you can no longer see the garden. These crystals interfere with the flow of electricity in and out of the battery. The battery will take longer to charge and a charge will last less time. A perfectly good battery will seem dead because lead sulfate has built up on the plates.

The BLS is the Solution

The Battery Life Saver electronic device solves this problem by dissolving the buildup of lead sulfate crystals. The BLS sends a radio signal through the battery, targeting the lead sulfate crystals (even those that could not be dissolved by recharging), converting them back into lead and sulfuric acid. Each crystal is like a tiny radio receiver. In fact, when the radio was invented, a lead sulfate crystal was used for the receiver. The BLS action gradually restores the battery back to its original condition and allows the electrical charge to be drawn from the battery.

Other Desulfators

Electronic and chemical desulfators have been on the market for years. How is the BLS different? The biggest difference is the ability to target the whole range of sulfate crystals that accumulate on the lead plates. As discussed above, regular electric current does not have the ability to do this. Electronic desulfators (commonly known as pulsers) send a high amount of voltage for a short period of time throughout the battery to knock down the crystals (similar to overcharging). They are unable to dissolve all the different types of sulfates. You can get some initial apparent improvement but the continued use of these other desulfators can cause two negative effects on the battery:

1.) If you continue to use the pulser, the crystals will continue to accumulate at the bottom of the battery which can eventually cause a short cell.

2.) The plates will become thinner and the sulfuric acid will become weaker because any lead sulfate that falls to the bottom of the battery cannot be recovered.
The Battery Life Saver electronic device dissolves the lead sulfate crystals that are covering the plates, converting them back into the original elements. It rejuvenates the sulfuric acid solution as well as the lead plates.

Connecting and using the Battery Life Saver electronic device

Connecting and using the BLS is very simple, just connect it and forget it! The device works off of the power of the battery, and therefore does not have to be plugged into AC power. All of the units come with two leads(wires) just like jumper cables.
Some units are equipped with alligator type clips and others come with eye rings for permanent attachment to the batteries.

Sample Connection

The following pictures show you how to connect the Battery Life Saver electronic device to a battery system. The example system
is the same battery arrangement of a 36 volt Club Car DS, it is six 6 volt batteries connected in series.

The main positive and main negative terminals are the same battery terminals that the charger or charging source cables are connected.
First connect the black wire from the Battery Life Saver electronic device to the Main negative battery terminal.

Next connect the red wire from the Battery Life Saver electronic device to the Main positive battery terminal.

The BLS is now connected and the LED be on. Finally, securely fasten (with self tapping screws or Ty Wraps) the BLS
to something metallic (for example the metal frame of a golf cart).


"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."
