#GITUP BATTERY CHARGER HOW TO#

If your battery has a capacity of 2500mAh and you charge it with a current of 2500 mA, then you are charging it at a rate of 1C. The Charge rate (or C-rate) is measured relative to the capacity of the battery. The method that you use depends mostly on how fast you want to charge your battery. There are a lot of different ways that you can charge a NiMH battery.

How to Charge NiMH AA Batteries Increasing the C-rate will charge the battery faster, but will increase the risk of damaging it

10 ohm Power Resistor (rated for at least 5 watts).

So for simplicity, we are going to focus on the most common type of AA rechargeable battery, Nickel-Metal Hydride (NiMH). We can’t cover all the battery types and charging methods in this article. As a result, each type of battery needs to be charged differently. Each type of battery uses a different chemical process to make it work. So here is how to build an Arduino controlled battery charger.įirst it is important to point out that there is no universal charging method that is appropriate for all rechargeable batteries. You could spend a lot of money on a commercial charger, but it's much more fun to build one for yourself. In order to get the most out of your rechargeable batteries, they need to be properly charged. They can save you a lot of money and when properly recycled, they are much better for the environment. Rechargeable batteries are a great way to power your portable electronics. An Arduino and attached charging circuit can be used to monitor and control the charging of NiMH rechargeable batteries, here's how:
