    1. What happens in a cell as it discharges

    As a cell discharges lead sulphate forms on both the positive and negative plates through absorption of acid from the electrolyte. The quantity of electrolyte in the cells remains unchanged. However the acid content in the electrolyte reduces, something noticeable in the change of the specific gravity.

    1. What happens during charging

    During charging the process is reversed. On both plates acid is released, while the positive plate converts into lead oxide and the negative plate into porous, sponge-like lead. Once charged the battery can no longer take up energy, and any further energy added is used to decompose water into hydrogen gas

  2. How A Battery Works


    A battery stores electricity for future use. It develops voltage from the chemical reaction produced when two unlike materials, such as the positive and negative plates, are immersed in the electrolyte, a solution of sulfuric acid and water. In a typical lead battery, the voltage is approximately two volts per cell, for a total of 12 volts. Electricity flows from the battery as soon as there is a circuit between the positive and negative terminals. This happens when any load that needs electricity, such as a radio, is connected to the battery.

    The Discharging and Charging Process of A Battery

    Lead batteries operate in a constant process of charge and discharge. When a battery is connected to a load that needs electricity, such as a starter in a car, current flows from the battery and the battery begins to discharge. As a battery begins to discharge, the

    Inverters and Converters - and why RV’s Use Both

    Inverters and Converters - and why RV’s Use Both

    When it comes to electricity, understanding important dissimilarities can mean the difference between a fun time and a hazardous situation.

    For example, RV’s, unlike cars, use both types of electricity – AC and DC – in order to travel as well as fully take advantage of all their accommodations. However, some of the more technical components involved with powering one, such as inverters and converters, can overwhelm the casual traveler often leading to lax servicing or worse. But in reality, these are simple terms that can be explained with a few quick tidbits that will maximize entertainment during your nomadic experiences.

    In other words, there’s no excuse not to learn a few quick tips brought to you by your favorite

    Hurricane Season Preparation for Generators

    It’s officially hurricane season – it’s hot, wet, and precious commodities are flying off the shelves faster than projected wind speeds.  

    Thankfully, you have your trusty generator to keep your family comfortable in case the power goes out.  But when was the last time you tested it to see if it works?  We tend to put them away until an impending storm is approaching fast, in which time we’re in a mad scramble to stock up on water, canned goods and gasoline, but not all of us has checked if the battery in our generator is ready to kick it on should the moment come. 

    That’s why Ba

  8. Which Optima Battery is right for you?

    Which Optima Battery is right for you?

    Which Optima Battery is right for you? RedTop, YellowTop, or BlueTop?

    The REDTOP Optima is a Starting Battery: Use this for normal engine starting where an alternator immediately monitors the state of charge and provides energy to the battery whenever it is needed. This would describe most stock vehicles.
    Also use for:
    • Automotive and RV under-hood starting
    • Heavy equipment where starting is the primary function
    • Diesel-powered vehicles with no aftermarket electronics
    The YELLOWTOP Optima is a Deep-Cycle Battery: Use this when electrical loads are higher than average, or when the discharge cycle is more than typical engine starting, such as vehicles without alternators. This also includes vehicles

  9. Does a battery self-discharge? Yes!

    All automotive wet batteries will slowly loose charge when not in service. This is known as self-discharge.
    Standard maintenance free batteries containing certain grid alloys, self-discharge at a lower rate than deep cycle batteries. The rate of self-discharge increases with increasing temperature; this is true for both maintenance free and deep cycle batteries.
    Allowing batteries to stand for an extended period of time without recharging them, will result in reduced performance and service life. To preserve optimum battery performance and life, recharge batteries in storage when the open circuit voltage drops to 12.4 volts.
    To make up for self-discharge while in stock, a boosting charge should be given to batteries whenever they fall .040 points in specific gravity, corrected to 80°F (26.7°C). T
