krispots said:hi, can anyone explain to me what does it mean when you say "charging at a rate of 0.1C"
what does C means? are you charging at a rate of 0.1 coulomb per second?
first link when googling: battery charge rate of c said:http://www.greenbatteries.com/batteryterms.html" - Used to signify a charge or discharge rate equal to the capacity of a battery divided by 1 hour. Thus C for a 1600 mAh battery would be 1.6 A, C/5 for the same battery would be 320 mA and C/10 would be 160 mA. Because C is dependent on the capacity of a battery the C rate for batteries of different capacities must also be different.

The term "Charge Rate Q: 0.1C" refers to the rate at which a battery is charged, expressed as a multiple of its capacity. In this case, 0.1C means that the battery is charged at a rate equivalent to one-tenth of its capacity per hour. For example, if a battery has a capacity of 1000 mAh, a charge rate of 0.1C would mean that it is being charged at a rate of 100 mAh per hour.
The charge rate of a battery is determined by its manufacturer and is based on its chemical composition, design, and intended use. The charge rate is typically stated as a multiple of the battery's capacity, such as 0.1C, 1C, or 2C. It is important to follow the recommended charge rate for a battery to ensure its optimal performance and longevity.
A charge rate of 0.1C is relatively slow and gentle, which can help to prolong the lifespan of a battery. It also allows for a more controlled and efficient charging process, as the battery is not being charged too quickly. This can prevent the battery from overheating or becoming damaged, and can also help to maintain its overall capacity over time.
The main disadvantage of using a charge rate of 0.1C is that it can significantly increase the charging time of a battery. This may not be ideal for situations where a quick charge is needed, such as in emergency situations. Additionally, some batteries may not be able to handle a charge rate of 0.1C and may require a higher rate for proper charging.
No, the recommended charge rate for a battery varies depending on its chemistry and design. Some batteries, such as lithium-ion batteries, are designed to handle a higher charge rate, while others, such as lead-acid batteries, may require a lower charge rate. It is important to consult the manufacturer's specifications to determine the appropriate charge rate for a specific battery.
