The newer type of sealed, non-spillable, maintenance-free valve-regulated battery uses an “Absorbent Glass Mat” or AGM separator between the plates. This is a very fine Boron-Silicate glass mat. These types of batteries have all the advantage of gels but can be subject to more abuse. AGM batteries, like gel batteries, do not leak acid if broken.

The advantages of AGM batteries are that they require no maintenance, are sealed against fumes, hydrogen, leaks, or non-spilling even if they are broken, and survive most freezing conditions. AGM batteries are “recombined” – this means that oxygen and hydrogen are recombined inside the battery. They take advantage of the gas phase transfer of oxygen to the negative plate, recombining them back into the water when charging, and preventing the loss of water through electrolysis. The efficiency of recombination is typically over 99%, so almost no water is lost. Most AGM batteries are charged at the same voltage as standard type batteries, so there is no need for special charge adjustments or problems with incompatible chargers or charge controls. Due to the extremely low internal resistance, the battery hardly heats up even under high current charging and discharging. AGM batteries have a very low self-discharge rate (1% to 3% per month). Therefore, they can be stored for longer periods of time without charging. The plates in the AGM batteries are tightly packed and securely mounted to withstand shock and vibration better than any standard battery.

Today, the plastic (polypropylene) used in battery cases is a good electrical insulator. In addition, there have been huge technical improvements in the seals around the battery column and ventilation system, which virtually eliminates electrolyte leakage and migration. Therefore, the battery can be stored on concrete. The discharge rate of a battery is only affected by its age, external temperature, and how the battery is manufactured inside.

The recycling process for used lead-acid batteries is a two-step process: separating the components of the old battery, then refining those components to make new batteries. A battery has three basic components: lead, electrolyte, and plastic. This plastic follows industry-wide recycling processes and is often used to remanufacture new battery cases and covers. Since mining lead is the least efficient way to make new batteries, every possible ounce of lead is reused to make new batteries. Lead is melted into ingots, which are easy to transport and manufacture. The electrolyte of some batteries is a mixture of sulfuric acid and water, which can be reused in new batteries. The rest is neutralized and used to make textiles, laundry detergent and glass

Corrosion can impair battery performance. It also affects the entire car’s electrical system. So you’ll be wondering how to properly clean a car battery from corrosion.

1. First, put on safety gloves and glasses.
2. Remove the negative cable from the battery. Then disconnect the red positive cable.
3. Get an old toothbrush, some baking soda and water.
4. Create a cleaning solution of one part baking soda and five parts water.
5. Then, scrub the terminals with a toothbrush and baking soda mixture.
6. Rinse with water.
7. Finally, dry everything before reconnecting the cables.
8. Connect the positive wire first, then the negative wire.

Different usage applications will use different methods for evaluating a battery’s performance. Using a 20 hour rate or the 10 hour rate, you can use 0.05CA or 0.1CA to discharge the battery until the battery reaches a terminal voltage of 10.25 volts. You can then calculate the amp hours to see if the battery fits the specifications or not.

For a 5 minutes rate, such as the HC1221W, you can use a 21 watts/cell discharge till the terminal voltage reaches a terminal voltage of 9.6 volts and then measure the discharge time to see if it meets the final specifications or not.
