Unfortunately, lower priced chargers are prone to incorrect charging. Most modern chargers developed for nickel-based batteries can accommodate both battery types. Nickel metal hydride batteries: The charging of an Ni-MH battery implements a more complex technical process than its cadmium sibling.
Since prolonged trickle charges to a fully charged battery stresses it, unnecessarily delaying the removal of your charged batteries from the charger is discouraged.
Charging lithium batteries full#
Upon full charge, nickel cadmium batteries will continue to receive a minimum trickle current to offset their self-discharge. Once plateaued to full capacity, performance will begin to gradually decline. While quality cells can perform optimally after 5–7 cycles, cheaper cells may require 50 cycles or more to perform at their rated specification. The optimal performance of a NiCad battery is connected with its quality. It will also facilitate the redistribution of a battery’s electrolytes which tend gravitate to the bottom after prolonged storage. Charging will serve to equalize the charge levels of the battery’s cells which may have independently discharged at variable rates. NiCad batteries should be charged for 16–24 hours prior to use, unless otherwise provided on accompanying instructions. Nickel-cadmium batteries: Similar to lead-based battery systems, newly purchased NiCad batteries are not fully formatted or primed by the manufacturer. This makes nickel chemistry batteries more complex to charge. Unlike lithium and lead-based chemistries, which are charged with a regulated current, the voltage rises freely. A full charge is reached when there is a slight drop in voltage following a steady rise.
Let’s take a brief look at charging these chemistries and a few rules of thumb.īoth the nickel metal hydride (Ni-MH) battery and its predecessor, the nickel-cadmium (Ni-Cd or NiCad) battery, are charged using a method called constant current constant voltage (CCCV). One of them is priming, which warrants charging recommendations for different battery compositions-specifically, batteries of nickel, lithium, and lead-based chemistries. In a previous article, Practical tips to maximize battery life, we discussed some of the different ways that you can prolong your battery’s service life.
