The letters and numbers in the code indicate the number of cells, cell chemistry, shape, dimensions, the number of parallel paths in the assembled battery and any modifying letters deemed necessary. A multi-section battery (two or more voltages from the same package) will have a multi-section designation.
What do the numbers and letters on A battery mean?
Date Code: Most batteries have a date code, usually a long string of numbers and letters that show when the battery was purchased. One row of one- or two-letter codes indicates the month, the other row of numbers is the last digit of the year.
What does 10s mean in batteries?
Ten cells in series would give us 10 x 3.7V = 37V nominal, which is why most 36V li-ion battery packs use a 10s (10 cells in series) configuration. Here’s a list of voltages and their corresponding cell counts: Number of cells in series. Nominal voltage of battery pack.
What does Ch mean on A battery?
Battery discharge (DCH) and charge (CH) with 0.75 C and relaxation phase (Relaxation) beginning at 0 s with the current switched off. Indices indicate the voltage drops at the respective resistances.
What does V stand for battery?
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours).
How do you read a battery label?
The first character will be a number from zero through nine that corresponds to the last digit in the year in which the battery was manufactured. For example, a five would mean 2015. The second character is a letter that refers to the month the battery was made.
What does N70 battery mean?
N70. Type of rechargeable battery that supplies electric energy to an automobile. An automotive SLI battery(starting, lighting, and ignition) powers the starter motor, lights, and ignition system of a vehicle’s engine.
What does S and C mean with batteries?
“S” is number of cells in series. “P” is number of batteries in parallel. “C” rating is the available discharge rate (eg. 3000mAh 20C = 60A discharge rate)
Can you use a 7.4 V battery instead of 7.2 V?
Of course, you can use a 7.4 volts battery instead of 7.2 volts on your RC car. However, it must be within the range of voltages the electronic speed control (ESC) of your car can handle. If 7.4 volts is not in the range of voltages and you use it, you could damage the motor and ESC beyond repair.
What is a 3S battery?
Lithium Polymer 3S batteries, also known as LiPo 3S batteries are lightweight and very powerful rechargeable lithium batteries. Lithium Polymer batteries feature electrolytes in the form of polymer gel with graphic anode and cathode in the form of a Lithium Cobalt Oxide (LiCoO2) or some similar material.
What does SMH mean on a battery?
SMF (Sealed Maintenance Free) batteries also known as the Valve Regulated Lead Acid (VRLA) batteries. These flat plate batteries that do not require topping-up and normally do not emit any fumes or gases on a continuous basis.The latest gas recombination technology ensures no emission of fumes.
What does Ah mean in battery?
Capacity – Amp hours (Ah):
Battery capacity is measured in Ah, or Amp-hours. As the name suggests this means how many amps the battery can deliver in an hour. For example, a 12V lithium battery with a capacity of 100Ah can deliver 100Ah to a 12-volt device for one hour.
Is 80v more powerful than 60v?
The higher the amp/hour rating the longer the battery will power whatever it’s hooked up to … like the big electric motor on a lawn mower. If you take the two 40v batteries and wire them in series, you get 80v …which means you might be able to run a higher horsepower electric motor than the single 60v battery.
What does 40V mean?
It is calculated by multiplying the battery voltage wih the capacity (in ah). The following example illustrates it: A 20V and 40V battery feature a capacity of 4.0 ah each. Hence the batteries can store energy of 80 wh (20V) respectively 160 wh (40V). That means the higher the voltage, the more energy can be stored.
What does CCA and MCA mean on a battery?
CCA is the cold cranking amp rating which tells you how many amps will be delivered to the engine in cold temperatures. MCA or marine cranking amps is conceptually the same rating, however, the CCA rating is based on amps delivered at 0℉ and the MCA rating is done at 32℉.
What do the letters mean on a motorcycle battery?
The first letter generally identifies the manufacturer (Y = Yuasa, E= Exide, F= Fiamm ou Fulbat…). E.g. Meaning of the battery number “YTX7L-BS”: “YT”: Manufacturer reference. “X”: High performance battery. “7”: Battery performance indicator.
What should a 12 volt battery read fully charged?
about 12.6 to 12.8 volts
A fully charged battery will typically display a voltmeter reading of about 12.6 to 12.8 volts. If your voltmeter is showing a voltage anywhere between 12.4 and 12.8, that means your battery is in good shape. Any voltage above 12.9 volts is a good indicator that your battery has excessive voltage.
What voltage is too low for a 12-volt battery?
The lifespan of your battery will be moderately affected if it remains within this voltage range for extended periods of time. 12.0 volts or below – At 12.0 volts your battery is considered to be fully discharged or ‘flat’ and should be recharged as soon as possible.
How long will a 12V 12ah battery last?
approximately 120 hours
The watts/volts are equal to the amps per hour. A tiny device such as led lighting of power 1.2 watts running on a 12volt power source will use 1.2W/12V = 0.1 amps. Therefore, a 12ah (amp-hour) battery will last for approximately 120 hours.
Does a higher Ah battery give more power?
In general, higher amp hours mean more runtime and higher voltage means more power.
What is 2C in battery?
1C is equal to 60 minutes, 0.5C to 120 minutes and a 2C rating is equal to 30 minutes. The formula is simple.
