In this guide, we'll walk you through a tried-and-true Ni-Cd battery charging circuit designed to safely recharge your batteries while including important protection features to keep everything run.
The NiCd Battery Charger Circuit is one of the most commonly used devices for different electronics projects.
The NiCd Battery Charger can charge a 12V NiCd battery pack. However, you can likewise charge 6V and 9V battery packs. When you give the input capacity to the NiCd Battery Charger Circuit, you will get the ideal output for various battery packs. This circuit is using a transformer that can convey a 4A current somewhere in the range of 12V to 16V.
As opposed to lead-acid batteries NiCd batteries must be charged with a constant current. Typical NiCads needs to be charged with a current that must be 1/10th value of its mAH rating, and charged for a approximate duration of 14 hours.
Here are a few Ni-Cd projects you can construct: Typically, you can use this Ni-Cd circuit to charge standard AA size NiCad batteries. But if you plan to charge NiCad capacity cells, it's ideal to opt for a special charger. And that's because NiCad cells have a meager internal resistance.
In this 12V Ni-Cd charger circuit, a voltage doubler based on the popular 555 IC is used. Because output 3 of the chip is connected alternately between the +12 V supply voltage and earth, the IC oscillates. C 3 gets charged through D 2 and D 3 to almost 12 V when pin 3 is a logic low.
Also, the Ni-Cd battery packs are more tolerant and perform under harsh conditions. Further, the battery is more durable than lithium batteries or lead-acid batteries. And the device has high energy, like alkaline batteries. But what if you don't have a battery charger?
