Lead Acid Battery Maintenance by Puls-R International - Military


What are you doing to prevent your 12v lead acid batteries failing in your equipment?


Military missions, conflict prevention, crisis management and in particular the war against terrorism, require reliable equipment to support the military forces of many nations. In today's world of high technology military equipment, lead acid batteries still play a vital role.

Military equipment still uses lead-acid batteries in a wide field of military applications, especially for armoured and non-armoured vehicles, frigates and submarines.

When the Civil War began in 1861, the rechargeable lead-acid battery was in it's infancy, having been invented just two years earlier. Remarkably, the basic chemistry and functionality of lead-acid technology have remained essentially unchanged until now...

In the intervening 151 years, batteries have come to play a variety of key roles in all branches of the world's military forces. Communications remain as important an application as they were in the 1860's. It was, however, with the advent of mechanised warfare in the first half of the 20th century that batteries acquired a new significance as an essential part of the modern military inventory.

The U.S Army currently spends approximately $75 million annually on lead acid batteries alone.

Battery reliability in military applications is critical. Lives depend on it. At the same time, these applications place demands that push the nearly 150-year-old lead-acid technology to the limits of performance and beyond. Punishing conditions of severe vibration, temperature extremes, and prolonged idle states place extraordinary demands on these batteries.

PULS-R is a division of the internationally successful B. Hepworth & Co Ltd who specialise in the manufacture of safety critical systems for the marine, rail, passenger transport and commercial vehicle sectors.

PULS-R curently have a number of products out on test in a variety of industrial and military applications. Our mission is to increase lead acid battery performance within your market sector

Our mission is to increase lead acid battery performance within your market sector

The PULS-R is a quick and easy solution to the age-old problem of premature service life of lead acid batteries due to poor reconditioning and maintenance.

The PULS-R can be fitted in a couple of minutes and, when on standby, it draws only 3mA and emits a flashing blue LED.

As soon as it receives 13.7v and 0.5amp from any source it begins the reconditioning process and a continuous blue LED indicates the unit is working.

The Puls-R 12V what is it?

The Puls-R 12V is a battery conditioning device that attaches to the battery pole clamps of all standard 12v lead acid / gel lead acid / AGM batteries.

What does it do?

  • Increases your battery lifespan by at least 100%
  • Increases your battery capacity by up to 340%
  • Enables you to charge your battery faster

Replace your battery less often - environmentally friendly

Can restore older batteries in conjunction with a 12v charger

(providing there is no mechanical damage)

How does it do it?

Lead-acid batteries store energy by means of a chemical reaction between lead, lead dioxide and sulphuric acid (liquid or gel). After a while in operation, lead sulphate crystals form on the electrodes, reducing the capacity and service life of the battery.

Batteries treated with Puls-R 12V exhibit a significantly more homogenous lead dioxide structure on the positive electrode. The advantages: the electrode works more efficiently, the charging time is reduced and both capacity and service life are considerably increased.

Resulting in

Renewal of the active material in the battery

  • Promotion of the growth of fine lead dioxide crystals on positive electrodes for a more homogeneous and better functioning electrode
  • Transformation of lead sulphate crystallised on negative electrodes into lead and sulphuric acid
  • Reduction in the formation of larger lead sulphate crystals
  • Better protects your battery against poor charge management

In concrete terms this means PULS-R lead acid battery reconditioning and maintenance gives you a longer service life, increased performance and fewer charging cycles. Which means reduced maintenance costs, reduced replacement costs and confidence in your batteries.

Independent verification test results of a PULS-R 12v lead acid battery reconditioning and maintenance unit by MIRA

(Motor Industry Research Association)

The object of the test programme on a Puls-R 12V was to review the performance of the device. In order to do this, ten lead acid batteries were subjected to a controlled rapid discharge, recharged, then again subjected to a rapid discharge. This exercise was repeated 100 times to benchmark the performance of the 12v lead acid batteries.

  • 5 batteries were fitted with the PULS-R 12v unit (the blue line)
  • 5 batteries were not (the red line)

At the 1st cycle the untreated battery took approximately 2794 seconds (46 minutes) to discharge where the treated battery took approximately 2637 seconds (43 minutes).

No two lead acid batteries are exactly the same. This first test records that the averages of each two groups of batteries tested, the non treated battery group (the red line) actually had a longer discharge duration. Which means they were initially the better performing group, before the PULS-R had been activated. The PULS-R units only become active during the recharge cycle.

With the batteries recharged, then discharged 100 times -The effect of the PULS-R 12v was conclusive. The MIRA graph below illustrates their test results. The battery with the PULS-R (the blue line), significantly out performed the battery without the PULS-R 12v (the red line).

At the 100th cycle the untreated battery took approximately 966 seconds (16 minutes) to discharge where the treated battery took approximately 1742 seconds (29 minutes).

The final discharge duration of the treated battery is equal to 66% of the initial capacity and the duration of the untreated battery is equal to 34% of the initial capacity.

The other aspect of the test was to measure the capacity of both batteries over the 100 cycles. As you would expect the battery group which discharged for the longest duration initially also had the greater capacity.

Below you can see at a glance, that the battery group without the PULS-R 12v units (the red line), loses capacity rapidly and the decline is sustained throughout the 100 cycles. However the battery group with the PULS-R 12v fitted (the blue line) actually increases in capacity after approximately five recharge cycles and the decline is stabilised at 66%.

This is an example of the data used to calculate the change in capacity over 100 cycles. Data collected from battery 1 (treated) and battery 2 (untreated) was used to profile a graph of capacity against cycles. Samples were taken at 5 cycle intervals.

The capacity was calculated at each of these points and plotted on the graph.

After the 100 cycles the untreated battery had dropped in capacity by approximately 66% to a final capacity of 34% where as the treated battery had only dropped by approximately 34% to a final capacity of 66%.
