AGM battery is also called absorbent glass fiber mat, belongs to valve regulated lead-acid battery series, different from the first generation of liquid-rich lead-acid batteries, is based on the liquid-rich lead-acid batteries with poor stability, poor performance, prone to leakage and other issues invented, the internal electrolyte is no longer a liquid form of flow to improve the performance, safety and stability of the AGM batteries sealing and vibration stability, making it the ideal battery for vehicles, boats and so on.
The essence of AGM battery is still a lead-acid battery, in order to ensure the stability of the battery will be the original liquid sulfuric acid adsorption in the battery to the glass cushion separator, is located between the positive and negative electrodes to increase the surface area of the reaction, to ensure that the charging and discharging of ionic flow of efficient and stable.
(1) Maintenance-free, AGM is not liquid flow inside the battery can be placed at will, do not need to worry about electrolyte leakage, the battery is completely sealed reaction of the gas generated in the premise of not overcharging will be preserved inside the battery do not need to add water to the AGM battery.
(2) Dual-purpose batteries, AGM batteries can be used as dual-purpose batteries as a starting battery AGM batteries have lower internal resistance means that AGM batteries have a higher discharge power, has a higher voltage output than traditional lead-acid batteries faster and easier to start the engine. As a power supply battery AGM battery charging speed is 5 times faster than traditional lead-acid batteries, at the same time when discharging can maintain a stable current, slower discharge rate can be maintained for a longer period of time to generate electricity, but also for a deeper depth of deep cycle, the depth of discharge is 80%.
(3) anti-vibration, stability, AGM batteries have a shock absorbing effect of the glass mat between the lead plate, followed by the lead plate and the glass mat arranged in close proximity will not shift, so that the AGM batteries can simply cope with the ship’s vibration, in the use of vehicles are often used in off-road vehicles and other vehicles with strong movement.
(1) Cost, AGM batteries are more than four times the cost of traditional batteries, increasing the performance of each also leads to a rapid rise in battery costs.
(2) compatibility, AGM batteries are not used in all vehicles and boats, only to meet the requirements of the use of equipment to use AGM batteries, the same for the AGM battery charging needs to be slow and stable current to be equipped with a special charger, any other charger will lead to damage to the battery battery
(3) Overcharging, based on the shortcomings of lead-acid batteries AGM batteries are highly sensitive to overcharging, the battery is also more harmful.
Generally speaking, the life of the battery is 3 to 4, according to the different scenarios of battery use, the life of the battery is not the same, applied to the use of automotive batteries when the use of more frequent, extreme environments will also affect the life of the battery, the optimal use of conditions under the life of the AGM battery can reach 6 years or more.
(1) Usage, avoid long time placing of AGM batteries, frequently used AGM batteries will surely have a longer life than the long time using batteries, the batteries will cause more damage once they are fully discharged.
(2) Charging method, for AGM batteries you must use a customized charger, a mixed charger will surely reduce the battery life.
(3) the environment, the battery in extreme environments have a greater impact whether it is hot or cold weather battery operation will increase the possibility of AGM battery failure.
Lithium batteries, AGM batteries and lithium iron phosphate batteries belong to different material types of batteries lithium battery discharge mainly rely on lithium ions, lithium batteries in the selection of materials, better discharge can be stronger, naturally, higher energy density, the same capacity of the battery lithium batteries lighter, lithium batteries belong to the deep-cycle batteries than the depth of discharge of AGM batteries, lithium batteries are completely better than the performance of the AGM batteries, the life of more than 10 years makes the battery almost never need to be replaced. Lithium batteries almost do not need to be replaced, the price of lithium batteries although the price of lithium batteries is higher but lithium batteries have a better experience, preventing the operation of lithium batteries is really better.
The price of AGM batteries in a piece of about 250 U.S. dollars to use the performance can also meet the standards of vehicles and boats, 3 to 4 years of life is also much better than the liquid-rich lead-acid batteries, is a cost-effective good battery but compared to lithium batteries he can only be used as an alternative battery.
