1.) Is the BLS a charger?—No, the BLS is an electronic device that is used in conjunction with a battery charger. The BLS is powered by the battery. If the battery system is used and charged regularly, just attach it and forget it. If the battery system is not going to be charged for more than 5 days, you should disconnect the BLS or use the BatterySolver Package.

2.) How long does it take to rejuvenate a battery?—The amount of time needed to rejuvenate batteries varies based on a number of factors. It depends on how bad the battery is, the number of batteries that you will be reconditioning at a time, and how often you cycle (charge and discharge) the battery or battery system with the BLS connected.

Examples:

a.) If you have a golf cart and you use 3 to 4 times a week, you will start seeing the results within the first 2 weeks. It will continue to improve to an optimal

condition for another 1 to 4 weeks.

b.) If you have a badly sulfated 12 volt battery and you are using the BLS-12/24B, it can take between 3 and 10 cycles with the BLS connected to bring it back to a like new condition.

3.) Can the BLS rejuvenate my dead battery?—The BLS can rejuvenate any lead acid battery that does not have a short or open cell (Click Here for instructions on how to test for a short or open cell).

4.) What type of batteries will it work on?—The BLS is suited to work on any lead-acid battery. Various versions of lead-acid batteries include: GEL, AGM, VRLA, and Sealed. We are currently developing the technology for NiCad batteries.

5.) How long should I leave the BLS on the Battery?—To get maximum life out of your battery system, it is best to leave the BLS connected at all times. If you remove the BLS after the battery system is rejuvenated, the battery system will deteriorate as a normal battery would.

6.) Should I add new acid to the batteries?—When using the BLS, you should not add acid to the batteries. The BLS will dissolve the sulfate crystals, which will rejuvenate the sulfuric acid in the battery.

7.) How long is the warranty?—All BLS models have a 5 year parts and labor warranty.

8.) My BLS gets hot, is that normal?—The BLS does get hot when attached to a battery system that is deeply sulfated, the aluminum casing is equipped with cooling fins to help dissipate the heat. The BLS will get unusually hot if the system has a battery or batteries with a short or open cell (Click Here for instructions on how to test for a short or open cell).

9.) Do you have a 6 volt BLS?—No, there we do not make a BLS model for a single 6 volt battery. If you need to rejuvenate a 6 volt battery, connect two 6 volt batteries in series to make 12 volts and use the BLS-12/24B.

10.) My battery won’t take a charge, is it recoverable with the BLS?—Just because a battery will not take a charge, it doesn’t mean that the battery is dead. Most of the newer battery chargers are considered smart chargers. Smart chargers read the voltage of the battery, and if the voltage is too low, the charger will not turn on and consider the battery dead, which may not be the case. When using the BLS, a dead battery is a battery that has a short or open cell.

11.) My charger has a desulfator mode, is that the same as the BLS?—The BLS uses our own patented Wave² Restoration Technology. It has the ability to target and dissolve the whole range of lead sulfate crystals that accumulate on the lead plates. The desulfator mode in a charger is very similar to the technology that pulse type desulfators use. For a full explanation of how batteries work and how the BLS is different, please review “Understanding Batteries and the BLS”.

12.) Do I still need to equalize the batteries with the BLS?—No, when using the BLS, there is no need to equalize the batteries. An equalize charge sends a high amount of energy into the battery to knock down the sulfate crystals. Having the BLS connect to the battery system will keep the sulfate crystals from forming. We do not recommend this process as it prevent from getting the full benefits of the BLS.

13.) If I use the BLS, how long will it extend the life of my batteries?—If you are using the BLS on a new battery system, we can comfortably say that if nothing else goes wrong with your battery, it will double or triple the normal life.

14.) Will the BLS harm my battery?—If a battery system is not charged for more than 5 days, the BLS will drain the battery system. But this does not harm the battery, since BLS prevents the damage normally associated with deep discharging. You only need to recharge your batteries and continue with the desulfation process using the BLS. Please call us if you need help jump starting your batteries.

15.) How do I connect the BLS?— The BLS comes with two wires, one red and one black.

In general, connect the BLS wires in parallel with the charging source. 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).

16.) What is the voltage of my batteries?— To determine the voltage of a battery, first count the number of filler caps on the top of the battery. Each filler cap represents a battery cell, each battery cell is approximately 2 volts. If a battery has 3 filler caps, it is a 6 volt battery.

If you have multiple batteries in the system and you need to determine the total voltage, next , observe how the batteries are connected to each other.

If the positive battery terminal of one battery is connected to the negative battery terminal of the next battery and so on, the battery system is connected in Series. When a system is connected in Series, the total voltage is the number of batteries times the voltage of the batteries. For example, a system with 6 x 6 volt batteries connected in series is a 36 volt system.

If the positive battery terminal of one battery is connected to the positive battery terminal of the next battery, and the negative battery terminals are also connected this way, the battery system is connected in Parallel. When a system is connected in Parellel, the total voltage is equal to the voltage of one battery. For example, a system with 6 x 6 volt batteries connected in parallel is a 6 volt system.

Testimonials

"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."
