Many modern motorcycles and all-terrain vehicles (ATVs) on the market use AGM batteries to reduce likelihood of acid spilling during cornering, vibration, or after accidents, and for packaging reasons. The lighter, smaller battery can be installed at an odd angle if needed for the design of the motorcycle. Due to the higher manufacturing costs compared with flooded lead-acid batteries, AGM batteries are currently used on luxury vehicles. As vehicles become heavier and equipped …
Valve Regulated Lead Acid (VRLA) Batteries are popularly termed as maintenance free lead acid batteries. Each cell in VRLA battery will have a value (automating operating) to allow the gas to escape if developed by the over charging the cells and to hinder the entrance of oxygen from the air into the cell
The valve-regulated version of this battery system, the VRLA battery, is a development parallel to the sealed nickel/cadmium battery that appeared on the market …
The valve regulated, spill-proof construction of the Power-Sonic battery allows trouble-free, safe operation ... and a carefully controlled plate-making process to provide excellent output per cell. The high ... The basic electrochemical reaction equation in a lead-acid battery can be written as follows: Pb 2H2SO4 PbO2 Discharging PbSO4 2H2O ...
Lead Acid Battery vs. Lithium Ion
The United States Navy has flown valve-regulated lead–acid batteries (VRLA) for approximately 22 years. The first VRLA aircraft batteries were of a cylindrical cell design and these evolved to a prismatic design to save weight, volume, and to increase rate capability. ... The flight control battery on the Boeing 777 is a 5-year no maintenance ...
Lead-acid battery
This gave this battery its now generally accepted name "valve-regulated lead-acid battery" or VRLA battery. (Sometimes the (not correct) name "sealed lead-acid batteries" is found in the literature, e.g. in the Federal Regulations of the USA, concerning battery disposal, they are called "SSLA batteries (sealed small lead-acid ...
Valve-Regulated: SLA batteries are often referred to as valve-regulated lead-acid (VRLA) batteries due to their unique construction. These batteries incorporate a valve mechanism that allows for the controlled release of gasses produced during charging, thereby maintaining internal pressure and preventing excessive buildup.
Valve-Regulated Lead-Acid or VRLA, including Gel and AGM (Absorbed Glass Mat) battery designs, can be substituted in virtually any flooded lead battery application (in conjunction with well-regulated charging). Their unique features and benefits deliver an ideal solution for many applications where

BATTERY 101 - Valve Regulated Lead Acid (VRLA) Technology. Posted by Matthew Campbell on Mar 30, 2020 11:15:00 AM
1. Introduction. Valve-regulated lead-acid (VRLA) batteries are used in a wide-range of applications from stand-by power supplies to automotive applications due to their low-cost and high reliability [1], [2].Their main role in standby applications is to provide energy in the case of power failure.
A brief explanation of the Valve Regulated Lead Acid (VRLA) Battery, also known as sealed or maintenance-free batteries, a lead–acid rechargeable battery.
The VRLA design results in a much lower battery capacity when compared with traditional, flooded (excess) electrolyte, counterparts. A typical mass-distribution analysis for a 12 V, 84 Ah (20 h rate), GEL–VRLA battery for use in photovoltaic (PV or solar) energy-storage systems is given in Fig. 1 and Table 1, and is compared with …
Valve-regulated lead-acid (VRLA) batteries are sealed lead-acid batteries that use a valve to regulate the pressure inside the battery. They are also known as …
