The plating act like dendrites within the cell, causing short circuiting between the electrodes, which raises the internal cell temperature, resulting in thermal runaway, damaged cells, and possibly fire. Lithium batteries operate safely within their specified voltages, but charging them beyond their limits builds up ions at the positive terminal (anode), which form metal lithium plates. One particular concern is the risk of overcharging them. Over the years, factory fires, exploding cell phone batteries, and the grounding of an entire Boeing 787 fleet have demonstrated how potentially dangerous lithium batteries can be. Offers High-Precision Overcharge Protection XTAR VC4S 4 Cell LiIon-NiMH Battery Charger with LCD display Specifications Rik W.-Australia Option 2 - XTAR VC4S Lithium Charger “We use 11 wireless transmitters in a church setting so far the batteries and chargers have been operating very well with long usage time and fast charging.” Defective battery sensing: iPower 8 detects aged or damaged batteries that can no longer charge or function correctly.Multi-chemistry charging: Along with lithium-ion cells, iPower 8 supports multiple battery chemistries like nickel-cadmium and nickel-metal hydride and can charge different chemistries at once. Reverse polarity protection: iPower 8 detects wrongly connected batteries and prevents reverse charging that can otherwise lead to damage and serious injuries.IPower 8 features eight independent charging channels that can detect individual battery levels.Įach channel charges its assigned battery to total capacity, independent of the other channels and battery levels.Īs such, iPower 8 can deliver different charging stages concurrently, from the initial constant current charge (for deeply discharged batteries) to the final topping charge (for fully charged batteries). So if you’re charging multiple batteries simultaneously, some will only partially recharge. Such chargers automatically stop once the least discharged battery is restored. This means your batteries will have different recharge times, which is a problem for analogue chargers that can’t detect individual battery levels. Some cells have higher operating temperatures and, therefore, self-discharge faster, meaning similar battery types can have different depths of discharge (DoD) before charging. Lithium batteries all have slight differences due to their electrochemical nature-even cells manufactured in similar conditions and from the same batch. This feature enables chargers to detect and adapt to varying charge states ( cell balancing), prolonging battery life. Smart charging is a must-have feature for top lithium battery chargers, which is why iPower 8 is an excellent choice. I-POWER 8 x AA Lithium Fast Smart Charger Smart Charging Option 1 - iPower 8 Lithium Smart Charger We’ll be looking at each charger option and how they affect lithium AA batteries. Here are three excellent charger options for your lithium-ion AA batteries: It’s not until they need recharging that you start thinking about them.įortunately, there are plenty of charger brands to turn to, each with vital features like overcharge protection and display monitors that track charging progress. You probably don’t think much of lithium-ion AA batteries and barely notice their worldwide presence.
