• 1. How long should a battery last?

    There are a number of factors that can affect the life of a battery. Some of these factors include: climate, lack of charging application, the type of battery, usage, sulfation, etc.
    • Colder climates tend to be hard on batteries from a starting standpoint, while hotter climates tend to speed up the process of discharging and cause the batteries to dry out quicker. Batteries would function best if they are stored and used in “average” temperatures. Furthermore “average" climates are the best for long battery life.
    • A battery that is used on regular bases has the most chance of living a longer life.
    • Another factor that would affect battery life is the charging system of the application. Some applications have better charging systems than others.
    • Not charging your battery properly would typically trigger a phenomenon called sulfation. Sulfation could be defined as a build up of crystals on the plates of a battery that interferes with the charging process and shortens the lifespan of the battery.
    • One of the main reasons for short battery life is lack of proper charging. If left unused a battery should be charged at least once a month.
    • Sealed AGM batteries last longer. On average Sealed AGM batteries last between 3 and 5 years. With proper maintenance this type of batteries could last even longer – usually between 6 and 8 years. On average, conventional batteries would only last 2 to 3 years.
  • 2. What can cause a new battery to fail soon after installation?

    If soon after installation a brand new battery becomes unserviceable this might be caused by one or more of the following reasons: short circuit in the electrical system, faulty charging system, excessive ignition off drains or high parasitic drains, dirty or not properly connected battery terminals, deficient electrical capacity, improperly activated battery.
  • 3. What is the cause of sudden battery failure?

    In most cases when sudden battery failure occurs it is caused by an internal battery connection failure. The internal failures are usually a consequence of poor care and maintenance of the battery. In order to prevent such battery failures from occurring make sure you are doing regular battery maintenance.
  • 4. Why my battery does not hold a charge?

    When the battery is in an excessively discharged state it would not readily accept a high current charge. Even if it seams like the battery is accepting charge, the charging is practically occurring only at the surface level of the plates. In these cases, the battery must be charged for an extended period of time (up to 24 hours) at a low current flow.
  • 5. How do you determine whether a battery has been charged?

    The battery has been properly charged if:
    • The specific gravity of the acid is over 1.275 (only for conventional type of batteries).
    • Open circuit voltage is considered stabilized at 12.7v or higher and at 6.3v or higher for 6-volt batteries.
    • Maximum voltage output across battery terminals can be kept at constant level for a period of two hours.
  • 6. How can I determine if a battery starts to fail?

    All batteries fail at certain point of time. Some of the signs for potential battery failure are: low voltage, lower performance, swelled container no recharging and acid corrosion. As the battery starts aging it would typically start providing less capacity and this is not something unusual. When a battery fails to deliver 80% of its rated capacity it is an indicator that the battery has reached the end of its lifespan.
  • 7. Is there a maximum temperature for charging my batteries?

    When you are charging lead acid batteries, you should make sure that the temperature does not exceed 120oF. On reaching this temperature, you should take the battery off charge and allow it to cool off before continuing the charge process.
  • 8. How can a battery's state of charge be accurately measured?

    In order to determinate the state of charge of a lead acid battery you should measure the specific gravity of the electrolyte, with the use of a hydrometer. Another way to determinate the level of charge is to measure the voltage of the battery in an open circuit condition. This should be done with a voltmeter. To ensure an accurate voltage reading, you should let the battery rest and wait for the voltage to stabilize.
  • 9. Does overcharging damage batteries?

    Overcharging is harmful to batteries as it causes excessive current to flow into the battery. This would result in decomposition of the water in the electrolyte, which in turn would lead to premature aging. As a battery reaches high rates of overcharge it would start heating up progressively. As it gets hotter it would start accepting more and more current, which would cause it to heat up even more. This process known as thermal runaway is especially harmful as it can destroy the battery for as little as a few hours.
  • 10. Why should you charge your battery once a month?

    While the battery is kept unused, it discharges up to 0.5-1% per day. Warmer climate would typically cause this discharge rate to increase. You can compensate for this loss from disuse by giving your battery a boosting charge every month.
  • 11. What is the life expectancy of sealed lead acid batteries?

    A typical Sealed AGM battery lasts 3 to 5 years on average. 6 to 8 years is easily obtainable as long as you ensure a proper maintenance for your battery. Conventional batteries generally last only 2 to 3 years on average. The High-Rate Discharge batteries would typically have a life expectancy of up to 10 years in standby use.
  • 12. How "cycle use" and "standby use" can be defined?

    Cycle use refers to the direct power source. Cycle use can provide the power supply to power tools, portable electronic products. Cycle Use means that the battery is being discharged and recharged regularly. Cycle use is typical for applications like electrically powered scooters, solar lighting or material handling. Standby Use stands for back up power. It is generally applied for emergency power in order to prevent future damage caused by abrupt power outages. Standby Use is typical for batteries, used to provide backup power for applications such as Uninterruptible Power Systems (UPS), Alarm or Emergency Lighting. These batteries are float-charged in a stand-by mode and supply power only when the main power source happens to fails.
  • 13. What is battery float life?

    Battery float life is the life expectancy of a battery under continuous charge. It depends on factors such as the frequency and the float voltage, depth of discharge, and the ambient temperature.
  • 14. For how long sealed lead acid batteries can be stored?

    The recommended storage temperature for most batteries is 15°C (59°F); for most chemistries the extreme acceptable temperature is -40°C to 50°C (-40°C to 122°F). Lead acid batteries can be kept in storage for up to two years and while they are being stored they must always be kept in a state of full charge. Since all batteries continuously self-discharge over time, it is important to keep track of their voltage and/or specific gravity. You should give the battery a boost charge whenever it falls to 70% state-of-charge. This is commonly the case at 2.07V/cell or 12.42V for a 12V pack. (The gravity at 70 percent charge is roughly about 1.218.) Keep in mind that some lead acid batteries might have different readings. That’s why you should always check the manufacturer’s instruction manual and follow them closely.
  • 15. What does "VRLA", "MF", "AGM", and "SLA" stand for?

    The abbreviation "VRLA" stands for Valve Regulated Lead Acid, "AGM" means Absorbed Glass Mat "MF" stands for Maintenance-Free, and "SLA" stands for Sealed Lead Acid. All of these are terms that refer to the same type of battery.
  • 16. What is sulfation?

    Sulfation occurs when the battery has been left in a discharged state for a considerable amount of time. As the battery is in use, small sulfate crystals are being formed. These crystals are harmless and completely normal. However, if the battery is deprived of charging for an extensive period of time the amorphous lead sulfate converts into a stable crystalline that deposits on the negative plates. Furthermore, when the plates are being exposed to air, sulfation eventually occurs as a result of the low electrolyte level. Once the plates have been sulfated, the activity of the affected area is lastingly impaired, and the battery may not be able to restore to its original capacity anymore.
  • 17. Can an AGM battery be installed in any position?

    Batteries are commonly installed in an upright position. In some types of applications however batteries need to be tilted (sometimes at very extreme angles) or laid completely flat on their backs. AGM batteries that are labeled as "Factory Activated" could generally be installed safely in almost any direction. If you have any question regarding a particular battery/ application/installation please contact us and we will provide you with specific recommendations.
  • 18. Can we install a battery in a sealed enclosure?

    Batteries must never be charge or discharge in a sealed environment. Under certain circumstances including: extreme overcharging or short circuit) batteries would generate a mixture of gasses internally. These gasses might vent into the enclosure creating the potential for an explosion in case a spark ignites them. In general, ventilation inherent in most enclosures is sufficient to prevent such incidents from happening.
  • 19. How should a battery be maintained?

    If you want to prolong the life of your battery you should make sure it is maintained properly. In order to ensure proper battery maintenance, you should consider the fallowing instructions:
    • Keep the acid level between Lower and Upper lines. To determinate the acid level of a conventional battery you should check the leveling on the front side of its container.
    • Charge your battery regularly and don’t let them stay in a discharged condition, not even for a short period of time.
    • Charge your battery at least once in a month.
    • Keep your battery dry, top clean, and free of dirt.
    • Keep the battery terminals clean to prevent corrosion. Inspect the vent tube carefully to make sure that it is not twisted, bent or clogged.
    • Make sure the battery is protected from strong impacts or shocks.
  • 20. Why do the winter months seem to bring more battery problems?

    The main reasons for this is that batteries need to work harder in cold weather as charging efficiency tends to decrease as a result of the low temperatures. Besides, gasoline does not vaporize as easily in cold weather, which means that more battery cranking effort would be required in such conditions.
  • 21. Can you send me spec sheets of the following batteries?

    You can download the spec sheets you need in PDF form from the Products section of our website.
  • 22. What are the differences between AGM and Gel sealed lead batteries?

    Both Gel and AGM batteries are sealed valve regulated types, which enables them to be used in any position. They only defer in the way the electrolyte is immobilized within them. In the AGM sealed lead batteries, a glass fiber separator that functions like a sponge would absorb the electrolyte, while in a GEL sealed lead batteries the liquid electrolyte transforms into gel substance right after the battery is filled. GEL batteries utilize a different sort of separators, which are not absorbent but apart from that these two battery types have rather similar internal designs.
  • 23. In which direction does current flow in a battery?

    The conventional direction of current flow is from positive terminal (anode) to negative terminal (cathode), which is the direction of the electric field within the wire.
  • 24. Can I bend the terminals of the battery in the opposite direction?

    You should avoid bending the terminals of sealed lead acid batteries, as they are bonded in place with epoxy and bending the terminals may crack the epoxy, which in turn would allow electrolyte to leak out and to be replaced by air. This would shorten the battery life, and will void the warranty. It may also cause damage to the battery due to the electrolyte spillage.
  • 25. What is the AH supposed to be right out of the box?

    A brand new battery will have a capacity (AH) 5-10% lower than the rated capacity. The full amp hour will be reached after the battery has been cycled between 10 and 30 times.
  • 26. We have your batteries in storage, when should they be re-boosted?

    Generally, most sealed lead acid batteries have a low self-discharge rate. Thanks to that you can store a fully charged lead acid battery for as long as a year. However, it is important to make sure that battery is charged within six months after receipt to account for the storage from the date of manufacture up to the date of purchase. Otherwise, the battery could experience permanent loss of capacity as a result of sulfation. Keep in mind that the ambient temperature would typically influence the rate of self-discharge. As the temperature rises the self-discharge rate decreases.
  • 27. Can I purchase a battery charger from your website?

    Yes, you can. We offer a wide range of battery chargers. For further information you can check out our Products section.
  • 28. What size charger should I buy?

    The properly sized charger takes into account both the time interval between charges and the battery capacity. Applications where battery recharge must be accomplished within 8 to 10 hours, would typically require a three stage, automatic charger, rated at 20% of the battery capacity. For applications where cycling is sporadic, a charger with an output current rating between 10% and 13% of the battery's rated 20-hour capacity would be sufficient.
  • 29. Are lead acid batteries recyclable?

    Lead acid batteries are 100% recyclable. In fact, nowadays lead is the most recycled metal in the world. The plastic covers and containers of old batteries are neutralized, reground and reused in the manufacture of new battery cases. The separators are often used as a source if fuel for the recycling process.
  • 30. Where can I recycle my batteries?
