In the past, most power tools used lead-acid batteries. However, with technological advancements and upgrades, lithium batteries have gradually become the standard in power tools. Even many devices that previously used lead-acid batteries are now using lithium batteries instead. Why replace lead-acid batteries with lithium batteries?
This is because current lithium batteries have more significant advantages over traditional lead-acid batteries:
For the same battery capacity, lithium batteries are smaller, about 40% smaller than lead-acid batteries.
This allows for a reduction in tool size, an increase in the mechanical load-bearing space, or an increase in battery capacity to increase energy storage. Currently, for lithium-ion batteries of the same capacity and size, only about 60% of the cell volume in the battery box is temporarily used, meaning about 40% is empty.
Under the same storage conditions, lithium batteries have a longer lifespan, approximately 3 to 8 times that of lead-acid batteries.
New lead-acid batteries typically have a shelf life of about 3 months, while lithium batteries can be stored for 1-2 years. The storage life of traditional lead-acid batteries is far shorter than that of modern lithium batteries.
For the same battery capacity, lithium batteries are lighter, weighing approximately 40% or more less than lead-acid batteries.
In this way, power tools become lighter and more portable, the weight of mechanical equipment is reduced, and its power is increased;
Under the same battery usage conditions, the number of charge-discharge cycles for lithium batteries is about 8 times that of lead-acid batteries.
Generally speaking, traditional lead-acid batteries have a cycle life of about 300 times, while lithium batteries can have a cycle life of about 1,000-2,500 times. That is to say, one lithium battery is equivalent to eight lead-acid batteries.
Although lithium batteries are slightly more expensive than lead-acid batteries, their advantages make them a more popular alternative. Now that you understand the advantages of lithium batteries over traditional lead-acid batteries, would you consider replacing your old lead-acid batteries with lithium batteries?
