“Do not be desirous of having things done quickly. Do not look at small advantages. Desire to have things done quickly prevents their being done thoroughly. Looking at small advantages prevents great affairs from being accomplished”.
Confucius BC 551-479,
Chinese Ethical Teacher, Philosopher
That batteries have a finite life is due to occurrence of the unwanted chemical or physical changes to, or the loss of, the active materials of which they are made. Otherwise they would last indefinitely. These changes are usually irreversible and they affect the electrical performance of the cell.
Battery life can usually only be extended by preventing or reducing the cause of the unwanted parasitic chemical effects which occur in the cells. Some ways of improving battery life and hence reliability are considered below.
Sulphating is a common cause of battery failure. Reviver is a useful product for increasing your battery’s life span.
Sulphating in various kinds of batteries
UPS batteries: UPS systems use Sealed Maintenance Free (SMF) batteries. Some of these batteries have liquid electrolytes, while others have jelly, which doesn’t require water level checks. But these SMF batteries are not completely sealed and do emit gases, the electrolyte level does go down and these also lose capacity of UPS batteries gradually diminishes as the batteries becomes old, and a time comes when these batteries have to be replaced. UPS batteries use superior quality material in their core, yet sulphate is the main cause of their failure. These batteries easily rejuvenate and respond well to the reviver treatment.
Automobile batteries: Sulphating in car batteries leads to corrosion in battery plates, and the plate materials fall to the bottom of the battery. This is called shedding, and it takes place because of the high porosity in car battery plates that maximizes surface area, and thereby allows the maximum discharge that is required for starting-up the engine. Sulphating enters the porous cavities of the plates, harden and expands greatly, and breaks the plate’s area; it is not possible to revive a dead automobile battery. A reviver device is a battery maintenance product used to eliminate ‘shedding’. One reviver unit is attached to a vehicle battery, but can also maintain a number of vehicles by interchanging it between them for a few days, or by charging a few battery at a time with a battery charger along with a reviver. With this technology you can expect the engine to start quickly, the air-conditioner will cool better, the car’s headlights will be brighter, and the cost of battery replacement will be reduced, finally translating into a fully dependable battery.
Traction batteries: Traction battery plates are solid and don’t have the porous qualities of automotive batteries. These batteries discharge huge amount of amperage over a long period, as their plates are quite large, Thick and heavy. Shadding is absent because battery plates are not porous. Sulphating coats and insulates the exterior of the plate, not allowed the battery to charge or discharge. High temperatures are recorded in sulphated batteries because of the high resistance and insulation and excessive current drain. Since the plates are not heavily corroded, it is comparatively easier to rejuvenate a traction battery by using the discharge/charge cycles, re-strengthening the electrolyte, and allowing the battery to return to normal state. In the absence of sulphating, the battery is always stronger and has a long life. This in turn increases the running time of battery replacement cost is also reduced.
Let us now discuss in depth, what a reviver is all about. A reviver is a compact small electronic device, employing microprocessor technology, which is guaranteed to dissolve sulphate accumulation in new ones. This is because less electrical energy is needed for charging a de-sulphated battery. A reviver is also an eco- friendly device, as it helps reduce the disposal volumes of poisonous lead plates.
How does reviver technology work?
Electrical pulses are injected at a frequency that is equivalent to the resonant frequency of the sulphate crystals, with a fast voltage rise and short duration of DC. As a sulphate crystal resonate, it is able to become ionized and reform back into the electrolyte as an active material. Battery plates stay clean, providing more power, faster recharge speed, and cooler charging temperatures. Due to the complete absence of sulphating, there is no ageing effect, and this result in extraordinarily long battery life.
What the reviver does is electronically dissolve sulphate formations back into the electrolyte solution without taking the battery out of service. Reviver technology products are being used as preventive maintenance tools, to prevent the battery from mechanical damage caused due to sulphating. The reviver units can be used to rejuvenate acid batteries-ordinary cell, SMF, heavy-duty traction battery or a stationery cell.
Here are a couple of things to look on when you are planning on investing in reviver products.
Points to ponder
Here are a few points that you are bound to find useful when considering reviver technology
- The reviver units are manufactured according to approved international standards. Rating can be continuous or intermittent.
- The reviver current is between 0-4 amps and the frequency is 8000-12000 cycles/sec.
- All units are auto- activated when the battery is receiving charging current and automatically stop when charging stops. The switching on and off of the LED lamp indicates this.
- One reviver can rejuvenate a number of batteries connected in series or parallel, if the total voltage and ampere-hour ratings are suitable to the units.
- Reviver products are epoxy-moulded, shock-resistant, and waterproof and can withstand high ambient temperature.
Connecting a reviver is simple, Connect the red wire of the reviver unit the positive terminal and the black wire to the negative terminal of the battery. Make sure that the battery voltage corresponds to the reviver voltage. Now charge the battery as usual.
Some applications of reviver units can be found in automobiles, generator starting units, motor boats, ships, battery-operated toys, forklifts, trucks, vans, buses, electric cars, tripping units, UPS and inverters, golf carts, off-shore equipment and emer
