Types of Lead Acid Batteries
The lead acid battery is an electrical storage device that uses a reversible chemical reaction to store energy. They have a capacity of six or more volts, enough to power a vehicle or boat. Designed to serve multiple purposes, all the lead acid batteries provide either starting or deep cycle power. The only difference is in the amount and duration of power delivered.
Driven by diverse applications, two designations of batteries emerged. They are the sealed lead acid (SLA), which is also known under the brand name of Gel cell, and the valve regulated lead acid (VRLA). Technically, both batteries are the same. No scientific definition exists as to when an SLA becomes a VRLA. (Engineers may argue that the word ‘sealed lead acid' is a misnomer because no lead acid battery can be totally sealed. In essence, all are valve regulated.)
The SLA has a typical capacity range of 0.2Ah to 30Ah and powers portable and wheeled applications. Typical uses are personal UPS units for PC backup, small emergency lighting units, ventilators for health care patients and wheelchairs. Because of low cost, dependable service and minimal maintenance requirements, the SLA battery is the preferred choice for biomedical and health care instruments in hospitals and retirement homes.
The VRLA battery is generally used for stationary applications. Their capacities range from 30Ah to several thousand Ah and are found in larger UPS systems for power backup. Typical uses are mobile phone repeaters, cable distribution centers, Internet hubs and utilities, as well as power backup for banks, hospitals, airports and military installations.
Unlike the flooded lead acid battery, both the SLA and VRLA are designed with a low overvoltage potential to prohibit the battery from reaching its gas-generating potential during charge. Excess charging would cause gassing and water depletion. Consequently, the SLA and VRLA can never be charged to their full potential.
Today, the flooded lead acid battery is used in automobiles, forklifts and large uninterruptible power supply (UPS) systems.
Among modern rechargeable batteries, the lead acid battery family has the lowest energy density. The largest single application of lead acid batteries is for the starting, lighting, and ignition of automobiles, trucks and buses. A lead-acid battery has been widely applied as an inexpensive reliable high safety secondary battery for SLI (starting, lighting and ignition) and other purposes.

Hi, this is lissa, and I am try to tell something about leoch battery, such as automotive battery, motorcycle battery, golf carts battery, motive power battery, etc, hope you like it. And if you currently have some suggestions or advices, I am really appreciate if you tell me.
what deck settings should i apply for best quality sound with solid bass?
What should i change my settings on my deck to for the questoin above? Such as the EQ-M,EQ-H,EQ-L levels and the "80+" level or the HPF, or the "SLA"?? any suggestions would be great!! thank you!
I have 2 12's in my trunk, 800 watt amp, sealed box if that helps
Sounds like you have a Pioneer head unit. If you do, just a word of advice.... depending upon the model you have, the RCA outputs eventually lose shield. Okay... as far as your question, each person hears things differently. When I set up a system for customers at our shop, (provided you are using the built in amplifier on the head unit), I put the low eq level at 80hz. Depending on the head unit you are using and whether it has a subwoofer dedicated RCA out is going to depend on what to set the bass on. IF you turn the bass up on the head unit to get more out of the 12's, you will also be sending bass to the full range speakers (mids and highs) which will produce high distortion levels. To solve this problem would require the use of a separate amplifier on the full range speakers running through an active crossover network, or using an amplifier with an adjustable internal crossover. That way you can get more bass out of the 12's without damage to your full ranges. The sla control is actually designed to level out the volume differences from one source to another. It stands for Signal Level Adjustment. Basically when you go from radio to cd... if the radio plays low, but when you go to cd and it is really loud, you can adjust them equally to eliminate that problem. Most head units do this automatically, that is the reason I am assuming that you have a Pioneer head unit. Hope this helped! Live Loud!
SLA Revival w/ EDTA?
