The lead-acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead-acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.

The main benefit of the lead–acid battery is its low cost; its main drawbacks are large size and weight for a given capacity and voltage. Lead–acid batteries should never be discharged to below 20% of their capacity, [67] because internal resistance will cause heat and damage when they are recharged. Deep-cycle lead–acid systems often use ...
Peukert's law becomes a key issue in a battery electric vehicle, where batteries rated, for example, at a 20-hour discharge time are used at a much shorter discharge time of about 1 hour. At high load currents the internal resistance of a real battery dissipates significant power, reducing the power (watts) available to the load in addition to ...
Corporate titles or business titles are given to company and organization officials to show what job function, and seniority, a person has within an organisation. [1] The most senior roles, marked by signing authority, are often referred to as "C-level", "C-suite" or "CxO" positions because many of them start with the word "chief". [2]
A secondary cell produces current by reversible chemical reactions (ex. lead-acid battery car battery) and is rechargeable. [citation needed] Lead-acid batteries are used in an automobile to start an engine and to operate the car's electrical accessories when the engine is not running. The alternator, once the car is running, recharges the battery.

A comparison group was sent fliers promoting recycling. It was found that the neighbors that were personally contacted by their block leaders recycled much more than the group without personal contact. As a result of this study, Shawn Burn believes that personal contact within a small group of people is an important factor in encouraging recycling.
