NiCd batteries should ideally be charged using a constant current source. Unlike lithium-ion or lead-acid batteries, the voltage for NiCd charging is variable and can rise throughout the charging process. The recommended charging rate is around C/10 (10% of the battery’s capacity per hour).
During the first 70 percent of charge, the efficiency of a NiCd is close to 100 percent. The battery absorbs almost all energy and the pack remains cool. NiCd batteries designed for fast charging can be charged with currents that are several times the C-rating without extensive heat buildup.
If you have questions that are not addressed, please let us know and we hopefully be able to help. ‘NiCd’ is the chemical abbreviation for the composition of Nickel-Cadmium batteries, which are a type of secondary (rechargeable) batteries.
(See BU-807: How to Restore Nickel-based Batteries) While pulse charging may be valuable for NiCd and NiMH batteries, this method does not apply to lead- and lithium-based systems. These batteries work best with a pure DC voltage. After full charge, the NiCd battery receives a trickle charge of 0.05–0.1C to compensate for self-discharge.
Furthermore, it is recommended to discharge NiCd batteries completely before recharging them occasionally. This helps prevent memory effect—a phenomenon where the battery “remembers” its previous charge levels and loses capacity over time. Regular cleaning of both the battery terminals and charger contacts is also essential for optimal performance.
The recommended charging rate is around C/10 (10% of the battery’s capacity per hour). However, fast charging can be conducted at rates up to C (100% of capacity per hour), provided the battery is engineered to handle such conditions. 2. Initial Slow Charge New NiCd batteries benefit from a slow charge of 16 to 24 hours prior to their first use.
Nickel–Cadmium Batteries
Fast charging is a preferred method for charging Ni–Cd batteries, but it should be applied with good monitoring and control of voltage, temperature, and pressure to prevent overcharging and the creation of potentially hazardous conditions; 1 C charging rates are common for nickel–cadmium batteries and 4–6 C charging rates are also often used, charging a battery …
