NO! Please do not attempt this.

Unless a battery/cell of any type is specifically listed as being rechargeable, do not attempt to recharge. Nonchargeable batteries of all types which are subjected to abnormal charging can out gas hydrogen. If this gas is allowed to build up to about 30% concentration within the cell casing or a battery case, all that is needed for an explosion or fire is a small electrostatic spark. The warnings on these batteries are for real.

Now, if you have a rechargeable battery, make sure you are using the correct charger and you follow directions. Otherwise you may end up with the same result. Warnings about not mixing old new batteries in one device are also a big problem. There are many technical reasons for this. Suffice it to say, read and follow the warnings.

As battery technology continues to improve with higher and higher power densities, the danger of fire and explosion also increases. Maybe you've heard about cell phone explosions or laptop fires.

This is not urban legend.

Though it may work in some cases, it is strongly advised to keep them separate.

Rechargeable and alkaline batteries have slightly different voltages. Using both types in the same device causes them to drain unevenly and can also lead to other complications, possibly damaging the device and batteries.

Generally, alkaline batteries are best used for low-drain devices such as clocks and flashlights. They last a very long time with almost no self-discharge. Rechargeable batteries self-discharge considerably and are best used for high-drain devices such as cameras. That way, rechargeable batteries are drained fast enough that they don't lose much power by doing nothing.

Regular Alkaline batteries are not designed to be charged. Charging of these batteries can be possible but this process is dangerous and may cause the batteries to explode or leak.

Can you recharge alkaline rechargeable batteries in a NIMH charger?

While it is possible with some, but not all NiMh chargers, it is not recommended. Charging alkaline batteries can make them leak chemicals. Only attempt this if you are experienced with electronics and are willing to deal with leaking batteries. The batteries often leak while being recharged, but sometimes they leak later in the device they power. Even if they do recharge, you will probably only get about 5 cycles. I would highly recommend that you get some NiMh batteries. They only cost about 6 times as much as alkalines, but they can be recharged hundreds of times.

Why do you prefer NiMH batteries?

There are several advantages of NiMH batteries compared to ordinary alkaline batteries: 1. They can be recharged hundreds of time. So a single NiMH battery can literally replace hundreds of alkaline batteries over its lifetime. This saves money, results in fewer batteries being discarded, and uses fewer resources. 2. The voltage of NiMH batteries is relatively constant with use. The voltage of alkaline batteries decreases as the battery is used. For example a flashlight dims with use when using alkalines. But with NiMH batteries, it will stay bright until the batteries are exhausted. 3. Due to the low internal resistance of NiMH batteries, the voltage does not drop nearly as much under a load as alkaline batteries. 4. Also because of the low internal resistance, the capacity of a NiMH battery does not drop very much under heavy loads. This is why you can typically get many more shots with a digital camera if you use NiMH batteries rather than alkaline batteries. 5. NiMH batteries can deliver a much heavier current. Some devices, such as high power flashlights, cannot run (or cannot run for long) on alkaline batteries (at least on the highest settings). NiMH batteries are required to make the most of these devices. 6. Alkaline batteries may leak when they get old and/or are discharged too quickly. This can destroy whatever device they are used in.
