EBL Universal Battery Charger
FOR ANY TYPE OF BATTERIES
The EBL Universal Battery Charger (for example: SUNJACK USB BATTERY CHARGER )
will satisfy any user regardless of batteries in need of charging. A huge advantage of the model is its capability to work with batteries of various types and sizes. In particular, this charging unit is compatible with AA, AAA, C, D batteries (either NiMH or NiCd). Actually, it's a great benefit since various batteries have absolutely different requirements for charging. With the EBL Universal Battery Charger, there is nothing to worry about! You can charge up to four AA/AAA rechargeable batteries at a time or up to two 9V NiMH/NiCd ones. Thanks to the special circuit design, it's possible to mix and charge different types of batteries together.
It's important to mention that the model comes with multiple protections against electrical issues. It automatically cuts off charging current when detecting improper input voltage, short circuit, or non-rechargeable batteries.
SMART AND PRACTICAL
As you might know, nickel cadmium batteries (NiCd) need to be discharged completely before recharging as the frequent partial discharging leads to the “memory effect” which makes full charge no longer available. NiMH batteries are basically considered to be more tolerant to this issue, however, it's better to provide their complete discharge as well, since such approach ensures longer service life. For this purpose, the EBL Universal Battery Charger has the discharge function. To activate this mode, just press a special button. Another very useful feature is that the model comes with a large and clear display allowing you to get all data about the recharging process.
IF YOU BOUGHT NEW NIMH BATTERIES
To get the most out of your NiMH rechargeable battery cells, you need to completely discharge and recharge them again 4–6 times. These simple actions will allow you to maximize batteries' performance. The number of discharge/charge cycles varies depending on the manufacturing process.
Nitecore Rechargeable Battery Charger
A WIDE RANGE OF CAPABILITIES
There are good chances that the Nitecore Digicharger D4 will surprise you with its multiple advantageous features. Despite its relatively compact design, the device is capable of charging different types of batteries during one session. The smart charger is compatible with IMR, Li-ion, LiFePO4, as well as with NiMH and NiCd rechargeable batteries. Wide compatibility makes the Nitecore Digicharger D4 exceptionally versatile and practical. The device comes with special charging slots that allow you to juice up batteries of many types, sizes, and technologies applied during their production. In total, 4 independent slots are available to users.
SPECIAL FEATURES
The model comes with a user-friendly LCD display that provides all important data about the charging process in each of the four slots: charging status, time, voltage and current readings. This smart charger automatically detects a battery type and adjusts the output current and voltage to ensure "gentle" and safe charging. Two buttons on the side allow selecting certain battery types and specific charging parameters. A car adapter is a convenient addition to the appliance — you'll be able to charge your rechargeable batteries right on the go.
HOW TO EXTEND LI-ION BATTERY LIFE
Li-Ion batteries don't have a memory effect, therefore, these batteries can be recharged at any time, you don't need to wait until they are completely discharged. Many manufacturers evaluate the battery life based on the counting of complete discharge cycles. High-quality lithium-ion cells typically deliver 400–600 cycles. To prolong lithium-based batteries, you need to recharge them as often as possible, a partial discharge reduces stress and prolongs the battery life. Optimally, once the power level reaches to 10–20 percent, the Li-Ion battery should be recharged. It can prolong the battery life to 1000–1100 cycles.
