Car Battery Battery Amp Hours Chart

For instance at c 5 a battery might safely provide 26 8 amp hours.

Car battery battery amp hours chart. That translates to about 5 amps an hour. Car battery specification charts showing dimensions sizes cranking amps voltages terminal weights and ampere hours call 01603 462959 pure tyre 01603 462959. For example if a battery is rated as say 8ah it will be able to provide 4 amps for 2 hours. If a battery is rated as 100ah it will produce 100 amps for 1 hour.

For example if you notice a battery is rated at 200 amp hours it tells you that the battery can supply 10 amps for 20 hours. It takes 18 25 hours to charge half of it s capacity at 2 amps 3 75 hours at 10 amps or 2 5 hours at 15 amps. 2 amps 18 25 hours 0 8 inefficiency 29 2ah being replaced 29 2ah already in the battery 58 4ah for a 550 cca battery. The 200ah car battery can uphold a ten amp draw for nearly 20 hours before it reaches 100 percent depth of discharge.

Most deep cycle batteries will tell you the ah rating at multiple c ratings. Draw from the battery for 20 hours and it will provide a total of 100 amp hours. The amp hours allow you to measure car battery amps through the practical lens. A rule of thumb is that for a 1 hour discharge rate i e.

This means that is supplies 26 8 amps in the. These numbers are given by the factory of a car battery and it is just a simple linear formula. This is something you ll see most often associated with deep cycle batteries used for recreational and marine vehicles. The car battery capacity of 1 amp hour should be able to continuously deliver a current of 1 amp to a load for 1 hour 2 amps for half an hour and so on before being completely discharged.

The power and longevity of a battery is noted by its amp hour ah rating. Charts that detail this effect for different discharge rate can be used for greater accuracy. The battery ampere hours chart. The c rating tells you how many amp hours the battery can provide for a very specific period of time.

Drawing 10 amps from a 10 amp hour battery or 1c you will only get half of the rated capacity or 5 amp hours from a 10 amp hour battery. What this means for a 100 ah rated battery is this. You can find these charts for car batteries as well though. A car battery amp hours chart shows the ampere hour expressed ah of the battery.

For large batteries the rating is abbreviated as ah. So when the battery comes with 100ah for 20 hours rate the battery can support 5 amps for about 20 hours before reaching a complete depth of discharge. Basically this denotes how long a battery will last if it isn t recharged.
