Your car’s starter battery is most likely either a flooded lead acid or anAGM电池, both of which are rechargeable battery types. 然而, how do a flooded lead acid and AGM battery differ from one another? We’ll compare AGM and lead acid battery to see how they compare. 然后, we’ll move to FAQs for more information on the car battery in this passage.
由于 AGM 电池是封装的,因此几乎不会排气. The chemical reaction’s gases and electrolytes recombined. A vent also releases additional gas when necessary to maintain internal pressure (例如, 当电池过度充电时).
AGM电池的玻璃垫和电池极板夹在中间, 这会导致零件不易分解. 这些特性使电池能够抵抗振动和压力, let them famous in motorbikes and race car. 震动和强烈振动可能会损坏进水的电池板, thus it’s important to mount them safely.
第四, 安装灵活性和防溢漏.
由于采用玻璃垫技术,AGM 电池对位置不敏感且防溢. It can be made up in a variety of ways, 但绝不颠倒. 然而, 充满液的电池必须始终保持直立,因为它含有液体电解质. If leakage electrolyte is not clear, 可能会导致腐蚀.
第五, 内阻与输出功率.
Among the numerous lead acid batteries, AGM 电池是内阻最低的电池之一. A fresh AGM battery can have an internal resistance of around 2%, 相比于 10-15% of a new flooded lead acid battery.
Low internal resistance of battery boosts battery voltage output. 此外, it means that less heat will be lost when the system’s electricity flows. In comparison to a flooded lead acid battery or gel, AGM 电池对负载的反应更好. Lead acid variants for start-stop cars are preferred due to their ability to regulate high power demands.
第六, 充电时间.
Faster charging periods are another benefit of the AGM battery’s low internal resistance. When using the same power source, the speed of a flooded lead acid battery can be up to 5 times faster than that of a lithium battery.
第七, 排出深度.
放电深度 (国防部) AGM 电池的数量是 80%, 这比 50% DoD of flooded cell batteries. 因此,AGM 电池是深循环应用的不错选择.
AGM battery is substantially less tolerant of overcharging than flooded lead acid batteries. 至于热失控, overcharging makes sealed design AGM battery is more pregnable. Even if thermal runaway is ignored, 过度充电会更快地缩短 AGM 电池的使用寿命. 所以, 为 AGM 电池充电时调节进入电池的电压和电流, utilize a controlled battery charger.
