SEALED LEAD ACID


EDUCATION - SLA Batteries


•  Is your battery different:  Yes, the capacity rating (shown in "ah") is slightly higher than what normally available. It is also fire resistant as is our wiring all hand soldered.  There are hundreds of battery manufacturers, some located no further than the back door of the usual Chinese plant and they get the throw outs under another name with limited capacity.

•  I might have to  put the battery on it's side.  My application calls for the battery to be inserted on its' side. Can this be done with sealed lead acid batteries?  
Yes. The batteries can be installed in any orientation.


•  What about draining my SLA battery to prevent memory effect?
  No, period!  Sealed lead acid batteries do not suffer from memory effect. Draining the battery may result in damage. 

•  Do I need to add water to my battery?  
No. Sealed lead acid batteries do not require the use of water.


•  What might have caused my battery to fail?
  It may have been under-charged or over-charged. Check your charging device periodically to ensure it is working properly.

•  
Sealed lead acid battery life is determined by many factors. These include temperature, depth and rate of discharge, and the number of charges and discharges.

•  Can my battery be shipped by air?
  Yes.  Most sealed lead acid batteries are declared non-hazardous for air shipping. Some exceptions apply. Like Singapore Airlines.

•  What are float chargers. A float application requires the battery to be on constant charge with an occasional discharge. Cycle applications charge and discharge the battery on a regular basis.
 

•  What is the difference between a Gel cell, an AGM and an SLA battery?


        *  A gel cell or gelled electrolyte is a sealed battery containing semi-solid electrolyte and may also be identified as a sealed lead acid, AGM(absorbed glass mat) or VRLA type battery. 

        *  AGM batteries are sometimes referred to as starved electrolyte because the fiberglass mat contained within the cell is saturated only 95% with acid and there is no excess liquid. 

        *  Nearly all AGM batteries are VRLA or valve regulated. VRLA batteries are designed with a valve that allows the battery to keep a slight positive pressure.

•  What is a marine or deep cycle battery?
   These are actually different types of batteries. The common marine battery is often rated to marine cranking amps.  It is designed to offer a quick shot of amperes in a very short time span. 

        *  These batteries can provide thousands of starts but can usually only withstand 50 or so cycles. A deep cycle battery is designed with the capability of being discharged and charged hundreds of times. Many of these batteries may be totally discharged or drained before they are ever recharged. The downside is the cost as much as four times a conventional battery.

•  All sealed lead acid batteries self-discharge. If the capacity loss due to self-discharge is not compensated for by recharging, the battery capacity may become unrecoverable. Temperature also plays a role in determining the shelf life of a battery. Batteries are best stored at 70 degrees F. When batteries are stored in areas where the ambient temperature varies, self-discharge can be greatly increased. Check the batteries every three months or so and charge if necessary.


•  I understand that batteries can be put together in series or parallel. What does this mean?
Connecting your batteries in series will generate a higher voltage. (Think Flashlight)   The total voltage is the sum of all individual voltages. 

Connecting the batteries in parallel will increase the capacity or amp hours. When you connect your batteries in a "string" (either in parallel or series) and find a battery that is not charging properly, we suggest that the entire string be replaced.
 (Think Bad Apple)
