There are five main things to watch for when charging and using batteries: Do not charge them above their maximum safe voltage (say 4.2V) - usually taken care of by any on-cell protection circuit; Do not discharge them below their minimum safe voltage (say 3.0V) - usually taken care of by any on-cell protection circuit; Do not draw more …
Rechargeable Batteries — compared and explained in detail
(NiMH''s are more tolerant of an over-discharge.) ... RAMs have the lowest self-discharge rate of any rechargeable battery—less than 1% of their initial charge per month. That''s way less than even the low self-discharge flavor of NiMH''s. This makes RAMs good for infrequently-used devices, or devices which take months to use up the battery (e.g ...

The Li-Ion battery will typically have a higher ESR (compared to Ni-Cd or Ni-MH), but will probably not be a problem in most applications. Self Discharge Self-discharge (which occurs in all batteries) determines the "shelf life" of a battery. Figure 4 shows typical self-discharge rates for the three chemistries, exact values will vary with ...
How rechargeable batteries, charging, and discharging cycles work
When the battery is in full charge the voltage is about 4.2 V. when the battery is fully discharged the voltage is about 3.0V. Li-ion battery comes in different sizes and shapes, the capacity is also available as requirements. Discharging of Li-ion batteries At the time of discharge of the battery, the Load is connected to the terminal battery.
Scientists study processes in rechargeable batteries because they do not completely reverse as the battery is charged and discharged. Over time, the lack of a complete reversal can change the chemistry and structure of battery materials, which can reduce battery performance and safety.
The batteries have a low-self discharge rate (the rate at which a battery loses charge over time) and are able to maintain 80 percent of their capacity for up to two years. Overall, they have a shelf life of five years which is the maximum life expectancy estimated for a NiMH battery. For this pick, no charger is included.

During charging, the positive active material is oxidized, releasing electrons, and the negative material is reduced, absorbing electrons. These electrons constitute the current flow in the external circuit. The electrolyte may serve as a simple buffer for internal ion flow between the electrodes, as in lithium-ion and nickel-cadmium cells, or it may be an active participant in the electrochemical reaction, as in lead–acid
This electron reversal process allows rechargeable batteries to be used again and again. Now, that''s not to say that you can buy a pack of rechargeable batteries and have it last you for life. Just like your smartphone battery life gets worse over time, rechargeable AA or AAA batteries will lose their ability to hold a full charge.
