Factors like battery type, capacity, and state of charge influence how much current is needed to charge a 12V battery. Generally, the charging current for a 12V battery is around 10% of the battery’s capacity.
A battery can supply a current as high as its capacity rating. For example, a 1,000 mAh (1 Ah) battery can theoretically supply 1 A for one hour or 2 A for half an hour. The amount of current that a battery actually supplies depends on how quickly the device uses up the charge. What Factors Affect How Much Current a Battery Can Supply?
For deep-cycle batteries, a general rule of thumb is to charge at 10-13% of the battery’s 20-hour capacity rating. For instance, a 100Ah deep-cycle battery would require a charging current of 10-13A. Imagine you're charging a battery, and it's kind of like filling up a water balloon.
The current required to charge a lithium-ion battery can vary significantly. While the traditional guideline is to charge at a rate of 0.5C to 1C (where C is the battery’s capacity), many lithium-ion batteries can safely be charged at much higher rates. Why the Preference for Higher Charging Current in Lithium-ion Batteries?
On average, this works out at just under 5kWh per day. Mark has neither the financial nor practical means to install renewable technology. However, he can use a home storage battery to take advantage of cheaper off-peak electricity rates, perhaps with the likes of the Octopus Flux tariff. Due to its compact size, Mark opts for the Giv-Bat 2.6kWh.
If we take a standard 100Ah 3.2V EVE Lithium cell (we need 4 of these to make a 12V battery). We can see it has the following specifications: As we can see, the standard charge/discharge current is 0.5C. Now, what is C? C stands for C-rate. To know more about C-rate, I recommend watching my video about it.
