What is the difference between Trickle charge and boost charge of a battery?
It's in the amount of current that is used to charge the battery. If the amp-hour (Ah) capacity of the battery is known, charging at the 5-hour rate or quicker would count as a boost charge, while charging at the 20-hour rate or slower would be a trickle charge. So for a 40 Ah battery, a boost charge is more than 8 amps while a trickle charge is less than 2 amps. A normal charge would be 4 amps.
Would a 36V 230 Ah 6hr 335 Ah 20hr traction battery charge on a DC volts24v DCamps20A battery charger?
NO, in order to 'charge' a battery, the charging device must be at a higher voltage than the battery in order for current to flow to the battery.
Will a 12 volt 75 ah battery charger can be used to charge a 12 volt 150 ah battery?
Yes. In about two to two and a half hours, depending on the condition of the battery.
How long to charge dead laptop battery?
Check and see how many Ah (Amper hours) your battery is. If it is for a gas/gasoline car, then it is probably around 42 Ah; batteries for diesel are usually around 72 Ah. Check the power of your battery charger. It should be something between 4-6 A. You must divide the battery capacity by the charger strength to get the time necessary. For example: your battery is 42 Ah and your charger is 6 A. Then the time needed will be 42 Ah / 6 A = 7 h. Charge your battery no longer than 7 h. Please note that overcharging the battery permanently damages it.
Can you connect 100 ah battery with a 130 ah battery?
It seems so. The only difference between the two is the amount of charge each holds. Sure! But they should have the same voltages. In that case if you connect them in series then you sum up their voltages. however, if they are connected in parallel, you then sum up their flow rate currents(ah). Example, if each is 12V, then connecting in series produces 24V. On the other hand, parallel gives 230 ah.
What does 15Ah means?
First 15Ah is something which you could see your battery. It is just the description of the amount of charge it contains. Electric charge is generally measured in coulombs(C) which is the SI unit. The commercial unit of charge is Ampere-hour (Ah) to put into succinity, 1 Ah = the battery can discharge 1 ampere current in 1 hour 15Ah = 15 amp current in 1 hour. 1 Ah = 3600 coulomb
How much backup of 150ah battery?
Ampere Hour (Ah)The capacity of the battery is represented in Ah. It is the amount of current a battery can give during one hour of charge / discharge cycle. High capacity batteries (100 Ah, 150 Ah) are used to power inverters to get sufficient backup time. The formula to select the battery power (Ah) is Load in watts / Voltage of battery x Backup hour.For example if you wants to run 400 watts load on 12 volt battery for 3 hours, then the capacity of the battery should be minimum 100 Ah.Ah = 400 / 12 x 3 = 100 Ah. If the load increases (within the capacity of the inverter), backup time reduces.
Do high capacity batteries last longer on charge?
The discharge time of a battery depends upon its Ah. capacity, Load current & rate of discharge. If a 150Ah battery rated for 10hours is discharged at 15A rate it should last upto 10 hours if the temperature and specific gravity of the electrolyte (in case of flooded type batteries) are within specified limits. If the same battery is discharged at 12.5 A it will last upto 5hours. 1. As the discharge rate increases the capacity of battery decreases. 2. As the temperature increases the capacity of battery increases.
Can you replace a battery that is rated at 4ah with a larger ah battery?
Yes, it mAh or Ah is how long the battery lasts, it does not affect performance.
How do you calculate the charge a car battery can hold?
You really can't calculate that, it's determined at manufacture. It'll be stated on the battery casing. Look for something saying Ah, Ampere hours.
Can 600 va ups charge 145 ah battery?
You would have to know the voltages of the battery and the UPS to know for sure. For example if the UPS' output is 120 volts, then it is capable of 5 amps of output. If the battery is also 120 volts, then it would take the UPS 29 hours to fully charge the battery. However if the battery was rated at 220 volts, then the UPS would never completely charge the battery. The source of the charging voltage must exceed the battery's voltage in order to fully charge it.
