Can you overcharge a rechargeable battery?
Don't overdo it. Overcharging occurs when the device or battery is plugged into a charger after full charge has been reached and may reduce battery life. Battery University recommends that nickel- and lithium-based batteries be stored with a 40 percent state-of-charge.
Can you leave rechargeable AA batteries on the charger?
A: No. They should always be removed when fully charged. Leaving them in the charger wastes electricity and can reduce the life of the battery.
Do rechargeable batteries lose their charge when not in use?
Many ready for use rechargeable batteries lose their capacity when not in use. That's why you still will have to charge them before using them. This phenomenon is called self-discharge.

How many times can you recharge AAA battery?
While one could attempt to recharge alkaline batteries, a full recharge isn't possible and there are inherent risks. Alkaline batteries are just not built that way. The nail in the coffin is the fact that a disposable alkaline battery can only be recharged 7 to 10 times, if that much.
Are rechargeable batteries worth?
Rechargeable batteries almost always last longer, cost less in the long term and reduce waste compared with single-use batteries and when used in high-demand devices. That's because many of them continue to work until being charged up to 500 times (2 to 5 years), offering hundreds of hours more use than disposables.

How much does an alkaline cell charger cost?
Being someone who does not like to be wasteful, I try to extend the life of “disposable” batteries. The cost of the alkaline cell charger ranges from US$15–35. The more expensive models can also charge all five consumer cell sizes (AAA, AA, C, D, 9V) as well as NiCd and NMH chemistries. The cost of alkaline cells is much less than NMH and Li-ion cells. So, recharging alkaline cells will further increase savings and less waste.

The typical charge time for these batteries is 3 hours; however, some chargers are known to do the same job in less than 2 hours.
Why do nickel batteries last longer?
Nickel Cadmium (NiCad): Nickel batteries last longer compared to alkaline batteries because of their higher power capacity and constant current flow that lasts till the battery discharges completely . NiCad batteries, however, are costly and cannot be used in all gadgets due to their output voltage of 1.2 V. The charging time for these batteries is 8 hours.
Why use AA batteries?
Users of battery-operated devices are increasingly opting for rechargeable AA batteries for obvious reasons. A number of modern household devices, such as audio players, cameras, flashlights, and toys, consume more battery power which calls for frequent battery changes. Thus, using rechargeable AA batteries makes sense from a long-term perspective.

How much current does a battery need to charge?
Normally, batteries are charged by supplying 10-20% current of their total current capacity.
How is the max voltage of a battery determined?
The max. voltage of the cell is determined by the materials in the battery and thus in the difference in potential between the two half reactions. The plain english translation of the previous sentence is that there are two main chemical reactions in the battery, a charging one and a discharging one. The voltage of the battery is the difference in energy between these two processes. In lithium ion its the difference between pulling/pushing lithium into graphite and the pulling/pushing lithium into a metal oxide (some flavor of CoO, NiO, FePO4, MnO2).
Why do rechargeable batteries need a full charge?
On the downside, these rechargeable batteries require a full charge as much as necessary because they self-discharge quickly, especially when they are not in use. This is also to prevent crystal formation that might make it impossible to revive the battery capacity. They are prone to memory effect and have a low 1.20 cell voltage which requires several cells before it can get a higher voltage.
