Recharge: By having a positive charge applied to the positive contact of the battery, and by having a negative charge applied to the negative contact of the battery.
Discharge: complete a circuit between both contacts of the battery.
Yes, a charged battery weighs slightly more than a discharged battery due to the additional mass of the stored electrical energy.
Sulfation can happen when battery is not fully charged and remains discharged
It is always good to charge a battery to its full capacity before it is fully charged.
An auto battery does emit hydrogen gas when it is being charged or discharged but it does not contain gas per se.
Usually from being discharged in below freezing weather. The water will freeze in a dead battery, expand, & swell the battery. This won't occur with a fully charged battery.
A battery float charger is intended only to keep a fully charged battery from losing its charge. It will NOT work to charge a battery that is discharged or damaged. Check the voltage of the battery to be charged. Do not use charger if the battery voltage is less than 9.6 volts.
The acid turns to water. Batteries will freeze in cold weather if they are discharged. When the battery is charged, the water turns back to acid.
Yes, it shouldn't be any different from leaving your cellphone with a discharged battery in it. If you have an immobilizer or alarm, it may require resetting once the battery has been charged.
A discharged battery can freeze in winter because it has a lower electrolyte concentration, which raises its freezing point. When a battery is fully charged, the electrolyte is more concentrated, making it less susceptible to freezing. A discharged battery has a higher water content relative to the acid, leading to a higher risk of freezing temperatures. Additionally, cold temperatures can further reduce the battery's ability to generate power, exacerbating the issue.
You sure can! I charge a marine battery with a 75 watt panel and it goes from a fairly good discharged state to fully charged in about four days.
A rechargable deep cycle battery can be fully discharged without damaging the battery. Any auto battery cannot be discharged without damaging the battery. Any dry cell rechargable battery can be fully discharged without damaging the battery.
Not a 'discharging' battery. Depends on the type of battery. A lead acid battery gives off Hydrogen when 'charging', which could be hazardous to health, if a spark causes it to explode. A 'discharged' battery can have an impact on it's own health. Best to keep them charged.
