Motorcycle starter lead acid battery manufacturers show you how lead-acid batteries work
Release time: 2023-02-21
The motorcycle starter lead acid battery manufacturer tells you that the grid structure of the lead-acid battery is made of lead alloy. Pure lead is too soft to support itself, so small amounts of other metals are added for mechanical strength and improved electrical performance. The most common additives are antimony, calcium, tin and selenium. These batteries are commonly referred to as "lead antimony" and "lead calcium".
Adding antimony and tin can improve deep circulation, but this increases water use and increases equilibrium demand. Calcium reduces self-discharge, but positive lead-calcium plates have the side effect of growing due to grid oxidation when overcharged. Modern lead-acid batteries also use dopants such as selenium, cadmium, tin, and arsenic to reduce the content of antimony and calcium.
Lead acid is heavy and not as durable as nickel and lithium based systems when deep cycled. Motorcycle starter lead acid battery manufacturers tell you that a full discharge causes strain, and each discharge/charge cycle permanently robs the battery of a small amount of capacity. When the battery is in good working condition, this loss is small, but once the performance drops to half of the nominal capacity, the decay will increase. This wear characteristic applies to all batteries to varying degrees.
Lead acid for deep cycle applications provides 200 to 300 discharge/charge cycles depending on the depth of discharge. The main reasons for its relatively short cycle life are grid corrosion on the cathode, depletion of active materials, and swelling of the cathode plate. This aging phenomenon is accelerated at elevated operating temperatures and at high discharge currents.
Charging lead-acid batteries is simple, but the correct voltage limits must be observed. Motorcycle starter lead acid battery manufacturers tell you that choosing a low voltage limit will protect the battery, but this will produce poorer performance and cause sulfate buildup on the negative plate. Higher voltage limits improve performance but develop grid corrosion on the positive plate. Although sulfation can be reversed if repaired in time, corrosion is permanent.
The motorcycle starter lead acid battery manufacturers tell you that lead acid is not suitable for fast charging, and for most types, a full charge takes 14-16 hours. Batteries must always be stored in a fully charged state. A low charge can lead to sulfation, a condition that robs the battery of its performance. Adding carbon to the negative electrode can reduce this problem, but this reduces the specific energy.
Motorcycle starter lead acid battery manufacturers tell you that lead acid has a moderate lifespan, but it is not as affected by memory as nickel based systems, and rechargeable batteries have the best charge retention.
