The small charging capacity is the biggest downside of this unit. Therefore, this might not be the correct option for those who require higher charging capacity. However, this charger has a 4 bay alternative: the Nitecore D4, which has exactly the same technical specifications, except it comes with 4 battery bays. See More
This charger is perfect for those who prefer to charge their batteries during the night. Battery chargers usually have a bright interface made of multiple LEDs or an LCD display. When used at night, such displays can generate lights bright enough to interfere with your sleep. This charger has a night mode to dim its screen and prevent this issue. See More
Once the battery is inserted, the user can change the charging current only for a very brief time period. After it passes, you will need to remove and reinsert the battery before being able to change the current settings. See More
There are multiple current options available on this unit: 200, 500, 700, and 1000 mA. By adjusting the charging current, you can vary the charging speed. For example, by using the 200 mA current option, you would need 3 hours to charge a standard 600 Ah AAA battery fully. The 700mA option, on the other hand, reduces the charging time of the same battery to approximately 51 minutes. However, charging too quickly can be detrimental to batteries as it may reduce its cycle life. The usual adequate charging current for AAA (NiCD and NiMH) batteries is 200-250mA (unless otherwise stated by a manufacturer). See More
While this product has a lot of useful features, you will not be able to use them without reading the entire user manual. The setup process is complicated, especially for new users. Be ready to invest some time and effort if you want to push this charger to its limits. See More
Apart from simply charging a battery, this unit can provide some useful information regarding the condition of the battery. Once the charge-up procedure is complete, the unit will display the exact capacity and output voltage of each battery. With the given data a user can assess the wear level of a battery and take the adequate measures when a battery is about to fail. See More
In order to increase the lifespan of a rechargeable battery, the user must fully discharge it from time to time. Not doing so can noticeably reduce the number of life cycles of the battery. This mostly affects those who recharge the batteries after short uses (photographers, for example). The BC1000 charger has an option that's convenient for those users, allowing to fully discharge the battery before charging it again. This function is called “Refresh” and it is recommended every 5 or 10 battery charge/discharge cycles. See More
