How long does it take to recharge a car battery after starting?
This is why a lead-acid battery needs the overpotential to charge - charging at exactly 13.8 Volts would never get it full. So, it doesn''t much matter how large your alternator is - the battery will take whatever it wants to take, and so it actually depends on the battery how long it takes to charge back after cranking the car. As the battery

6 FAQs about [How long does it take to ventilate the battery charging cabinet ]
Should a battery room be ventilated?
According to the National Electrical Code, (NEC) the battery room should be ventilated, as required by NFPA 70 480.10 (A). “Ventilation. Provisions appropriate to the battery technology shall be made for sufficient diffusion and ventilation of gases from the battery — to prevent the accumulation of an explosive mixture.”
What is the purpose of ventilation in a battery?
Occupational Safety and Health Administration (OSHA) Title 29 Code of Federal Regulations — Ventilation shall be provided to ensure diffusion of the gases from battery and to prevent accumulation of an explosive mixture.
What is battery room ventilation?
The room ventilation method can be either forced or natural and either air-conditioned or unconditioned. Battery manufacturers require that batteries be maintained at 77ºF for optimum performance and warranty. This article will look into the battery room ventilation requirements, enclosure configurations, and the different ways to accomplish them.
How many times a day should a battery room be ventilated?
The battery is 3m. Determine the ventilation rate to limit hydrogen concentration to less than 1%. Room Volume, RV = 4 x 2 x 3 = 24 m3. the room will need to be changed 4.79 times per hour, or about five times per hour. NFPA 70E. Battery room shall be ventilated at high points for removal of accumulated hydrogen.
How do you calculate the ventilation rate for a battery room?
Calculate the ventilation rate for a battery room consisting of 182-cell battery and 3 battery banks. Assume the battery room has dimensions of 20’ (l) x 15’ (w) x 10’ (h). FC = Float current per 100 ampere-hour. FC varies with battery types, battery condition, and electrolyte temperature. Ah = Rated capacity of the battery in Ampere hours.
Do you need ventilation for a battery charging area?
For example, if you are only charging one truck/battery you may not require ventilation or if your battery room is located in a very warm country like Mexico and you decide to have your battery charging area outside with just a roof over it, then you certainly don’t require ventilation as it is already open to the environment.
