Advanced American technology and the use of the most modern computer-aided design and manufacturing techniques combine to make MK Battery's Sealed Batteries the standard by which all other batteries are measured. In addition, the valve must safely release any excess pressure that may be produced during overcharging. While our gel cell will accept a charge extremely well due to its low internal resistance, any battery will be damaged by continual under- or overcharging.
If a battery is continually undercharged, a power-robbing layer of sulfate will build up on the positive plate, which acts a s a barrier to electron flow. For safety's sake, these potentially explosive gasses must be allowed to vent to the atmosphere and must never be trapped in a hermetically sealed battery box or tightly enclosed space!

Batteries vary by chemistry and configuration, which means that the required maintenance also changes. Sealed lead-acid batteries, gel cells, and absorbed glass mat (AGM) batteries are often called maintenance-free, because they don’t require manual maintenance like watering or an equalization charge. Lead-acid BatteriesLead-acid batteries should be recharged as soon as possible, with no exceptions. Parts of the plates that are sulfate cannot hold energy any longer, which reduces the effectiveness of the batteries and their lifetime. Remember, battery warranties never cover damage due to poor maintenance or loss of capacity due to sulfation, so proper maintenance is key.
Wet-cell or Flooded BatteriesWet-cell or flooded batteries need their electrolyte levels checked at least once every three months. Should the batteries show a variation of 0.05 or more in specific gravity from one another, they will need an equalization charge. With proper care as outlined above your batteries should remain in good working condition throughout their service life and serve well as part of any power system. Essentially, battery state-of-charge (SOC) can be easily measured using an amp-hour meter, by voltage, or by specific gravity.
An amp-hour meter is somewhat like a fuel gauge for batteries, providing all the information necessary to keep the batteries charged.


The voltage of a particular state-of-charge will vary depending on which state the battery is in; charging or discharging.
While a battery is idle, the temperature has little effect, although very high temperatures may increase the self-discharge rate. A hydrometer may also be used to measure battery state-of-charge in flooded lead-acid batteries by measuring the amount of electrolytes near the plates. To get an accurate reading from the hydrometer, take the readings after the battery has been idle for a long while, or after several hours of the battery slowly discharging. Whether a hydrometer or an amp-hour meter is used to measure battery state-of-charge, using them will allow you to determine where your batteries are in the stages of charging or discharging.

This means that the oxygen that is normally produced on the positive plate in all lead-acid battery recombines with the hydrogen given off by the negative plate.
It travels to the negative plate through tiny fissures or cracks in the gelled electrolyte.
If opened, the cell loses its pressure, and the outside air will "poison" the plates and cause an imbalance that destroys the recombination chemistry. Overcharging dries out the electrolyte by driving the oxygen and hydrogen out of the battery through the safety valves. These deep cycle batteries are sealed and maintenance-free ideal for remote application and stand alone systems.
Some of these maintenance tasks may be automated or performed remotely via charge controllers or battery management systems, including charge regulation, voltage checks, and related measurements.
While this makes them suitable for remote or unattended power systems, sealed batteries need accurate regulation to keep them from overcharging or over-discharging. This is because the positive plates change from lead oxide to lead sulfate as it discharges. For example, batteries that are only partially charged on a regular basis tend to fail in less than a year. If the cables are loose, do not attempt to tighten or remove them while charging or immediately after charging.


Measuring SOC by voltage or specific gravity requires specialized knowledge and a great deal of care, so it is recommended that owners utilize amp-hour meters for all battery systems. While using an amp-hour meter, users can see the system’s voltage, current, and battery condition. However, the electrolytes can only be measured at the very top of the battery, which may or may not be near the plates. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag.
Import charges previously quoted are subject to change if you increase you maximum bid amount. The "recombination" of hydrogen and oxygen produces water (H2O), which replaces the moisture in the battery.
Otherwise the recombination of the gasses will not take place, and the cell will dry out and not perform.
Although the normal gasses (oxygen and hydrogen) produced in a gel cell battery will be recombined as described above, and not escape, oxygen and hydrogen will escape from the battery in overcharge condition (as is typical of any type of battery).
We do not store batteries in our Emeryville office; our closest distribution center for pick-ups is in South San Francisco. Always carefully inspect all merchandise upon delivery; if you notice any damage please ask the driver about the correct protocol and always note it in the BOL or delivery receipt.
Should the plates be allowed to stay in a lead sulfate state instead of immediately charged, the plates will remain partially sulfate even when fully charged. While new lead-carbon batteries dramatically reduce sulfation, they still need to be recharged immediately to keep them in good working shape. If water is added while the battery is discharged, then the battery is recharged, the electrolytes will overflow and create a safety hazard. Any spark around the batteries has the potential to cause a hydrogen explosion inside the case, igniting a fire or causing a larger explosion.
