Gaston Plantש, a French physician invented the first rechargeable battery in 1859 that was based on lead acid. This system is still used in making batteries. Before this system, people were using primary batteries which cannot be recharged. Today, batteries have improved significantly. They come in different capacities and ratings like C20 battery rating. These ratings can be confusing. In this article, we will go over these ratings and also cover C20 and C10 batteries and their use.
What is C20 Battery Rating?
A C20 battery rating means that with a specific load attached to the battery, it took 20 hours for it to get discharged. This type of rating means that the battery is a medium discharge. This is one of the most common ratings used for batteries in the solar industry. However, it is conditioned that the battery should not be completely discharged within 20 hours otherwise its battery life is affected. If your battery drains faster, it means less energy is available to use.
What is C10 in Battery?
As a matter of fact, the C rating decreases with an increase in the number of hours because there are internal power losses and wastage in the battery. A C10 rating is regarded as a fast discharge as batteries with a c10 rating will discharge over a period of 10 hours.
The C rating is also a way of comparing batteries, especially the ones with the same output capacity. It is also an essential factor when choosing the battery because different appliances work with different battery ratings.
How Many Amps is C20? What is C20 Battery Capacity?
Amp Hour or C20 battery capacity indicates the amount of energy stored in a battery. It defines the amount of energy a battery can deliver continuously for 20 hours at 80°F without falling below 10.5 volts. On international levels, a C20 battery has 16 Amps and in North America, it has 20 Amps.

What is C20 Battery Charging Time? What is C20 Charging Rate?
C20 battery rating not only determines the discharging time of a battery but also indicates the charging time of a battery at a given voltage. For a given capacity, say c20 batteries, they are marked 20, which means they will reach the maximum Ah of battery within 20 hours.
The charging or discharging rate is determined by the amount of time a battery takes to fully discharge. Different batteries have a particular set of restraints and conditions that are related to their charging and discharging regimes. Also, some types of batteries require charging regimes and charge controllers. Therefore, the charging rate of a C20 battery is similar to its discharge rate.

What is C20 Battery Price?
C20 batteries are available in all forms and are used for various purposes. You can find C20 batteries in AA rechargeable batteries and in-car batteries too. However, their prices depend on the purpose they serve and the brand they belong to. Let’s understand this through these examples.
- For 20 AA Rechargeable Batteries NiMH 600mAh 1.2v Garden Solar Ni-Mh Light LED C20 batteries, you might need to pay around $14.99
- On the other hand, a Replacement Battery For Computer ternacell B9670B, Omron C120F Series, and C20 Series can cost you anywhere around $134.
Can We Use C20 Battery for Solar Inverter?
C20-rated batteries with 7.5A charging and discharging capacity are preferred for solar inverters. However, C5 batteries are more suitable for solar inverters connected to solar panels, if peak sun hours are 5-7 hours in a day.
Can You Use C10 Battery for Normal Inverter?
A battery rated with C10 provides more power over a 10-hour cycle, and you can use it with a normal inverter as well. As long as your battery has enough capacity to meet the needs of your appliances, your system will work just fine.
Well, after learning about the basics behind C20 battery rating and C10 battery ratings you can now easily distinguish between them. Can we use C20 battery for solar inverter? The answer to this is yes, you can use it for the solar inverter. However, it is always better to go with the advice of an installer as they know what is best for your solar panel system and its components. By the way, do you have a C20 battery for your solar inverter? If yes, we are awaiting your feedback and review for the same.
