Is Energizer battery rechargeable?
Energizer Recharge® Rechargeable Batteries. Environmental responsibility meets inspired technology – introducing the world's first AA/AAA rechargeable battery made with 4% recycled batteries. Now you can save money and have less impact on the planet by reducing the number of disposed batteries, creating less waste.
A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging.
- There are several important differences. The practical difference between Lithium batteries and Lithium-ion (Li-ion) batteries is that most Lithium batteries are not rechargeable but Li-ion batteries are rechargeable. From a chemical standpoint Lithium batteries use lithium in it's pure metallic form.
- This means a single cell can often be used rather than multiple NiMH or NiCd cells. Lithium-ion batteries also have a lower self discharge rate than other types of rechargeable batteries. This means that once they are charged they will retain their charge for a longer time than other types of rechargeable batteries.
- Energizer e2 lithium AA batteries produce 1.5 volts, so they can be used to replace any regular alkaline AA units in most cases. WEIGHT: Lithium batteries are much lighter than alkaline batteries. This is a great convenience for portable devices.
There are also some lithium-ion rechargeable batteries made for high-performance flashlights and cameras, in these sizes: 18650 and CR123. A single 18650 battery can replace two CR123A batteries, although at a lower voltage (but much higher amperage). There is currently no standard size for these lithium-ion cells.
- Batteries Allowed in Checked Bags: Except for spare (uninstalled) lithium batteries, all the batteries allowed in carry-on baggage are also allowed in checked baggage; however, we recommend that you pack them in your carry-on bag whenever possible.
- In brief: No, the 18650 cells can not be used in place of standard AA batteries, rechargeable or otherwise: The nominal voltage of the 18650 is significantly different from the 1.5x3=4.5V of the three AA cells, assuming those are connected in series.
- Figure 1: Charge stages of lithium-ion. Li-ion is fully charged when the current drops to a set level. In lieu of trickle charge, some chargers apply a topping charge when the voltage drops. The advised charge rate of an Energy Cell is between 0.5C and 1C; the complete charge time is about 2–3 hours.
