Battery problems are one of the leading causes of vehicle breakdowns. To reduce the
chances of battery failure, it is helpful to understand its causes. Most problems with
batteries can be avoided by following the regular care and maintenance practices
recommended by the manufacturer in the vehicle owner's manual. dell AC Adapters
Undercharging a battery causes sulfation, which is the chemical breakdown of battery
electrolyte. As the electrolyte breaks down, it adheres to the lead plates within the
battery, forming sulfuric crystals that slowly build up over time. hp AC AdaptersAs
sulfation occurs, the ability of the battery to hold a charge and provide energy is reduced
. Severe sulfation can result in a buildup of material between the lead plates in a battery,
causing internal short circuits between the plates.
A battery that is not used for long periods of time loses electrical charge, eventually
leading to a fully discharged condition and sulfation. Periodic use helps to replace
lost electrical charge and inhibit the start of sulfation that can lead to premature battery
death.
Temperatures over one hundred degrees Fahrenheit increase a battery's rate of internal
discharge. Batteries that do not receive periodic recharge in high heat conditions can lose
most of their electrical charge within twenty four hours. toshiba AC Adapters
Deep cycling is the repeated draining of a majority of a battery's charge. Automotive
batteries are designed to hold a steady state of charge, and repeatedly draining and
recharging an automotive battery drastically reduces its lifespan.Dell laptop keyboard
Electrolyte is the liquid within a battery that helps it to produce and hold an electrical
charge. When electrolyte levels become low due to leaks or evaporation, the lead plates,
or "cells," within the battery become exposed to air, which causes rapid sulfation.
In addition, low electrolyte levels reduce the amount of electrons the hp laptop keyboard
is capable of producing, lowering the overall electrical charge.
Parasitic drain is the presence of a load on the battery when the vehicle is not in operation.
Clocks, radios, lights and alarms are examples of parasitic drain, and all consume a small
amount of the battery's electrical charge when the vehicle is at rest. Unusual parasitic
drains such as leaving headlights on or electrical system malfunctions can drain the
battery in a matter of hours, allowing sulfation to begin if the battery is not recharged
immediately.toshiba laptop keyboard
Faulty voltage regulators or alternators can overcharge a vehicle battery. When this
happens, the excess electrical charge causes the plates within the battery to shed
material, increasing the battery's resistance to a charge. This shedding causes heat
to build within the battery, resulting in the evaporation of electrolyte.
