NiMH batteries must be charged first. The charge won't last as long as an alkaline battery but they can be recharged 100's of times. They have a slightly lower voltage (1.2 instead of 1.5) and should work fine in many devices. For an electronic device, you may see a low battery indicator because of the lower voltage.

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.


Will a NiMh charger charge NiCad Batteries?

Some will, but it is not recommended because it can damage the batteries or the charger. Invest in a NiCd charger or better yet get some NiMh batteries. NiMh batteries are better than NiCd in every way.


Flashlight that docks in a charger to recharge two AA nickel cadmium batteries so can an you replace these batteries with cadmium metal hydride ones?

you can change the nicad batteries for nimh without any problems, the charging will take longer as the capacity of the nimh batteries will be much higher than the nicad batteries.


Do quickcharge household battery chargers damage or shorten the life of rechargeable batteries as opposed to slow or regular chargers?

Not significantly. So long as it is done using a properly designed smart charger, most NiMH batteries can be recharged in about an hour without any damage or significant reduction in their life. However, NiMH batteries must only be rapid charged with a charger specifically designed for charging NiMH batteries. Chargers designed to rapidly charge NiCd batteries can overcharge NiMH batteries. While it may be true that rapid charging NiMH batteries can reduce battery life by a small amount (probably less than 10%), this should be more than offset by the inconvenience of always slow charging batteries.


How many watt hours in AA battery?

This question doesn't have a simple answer. It depends on the battery chemistry and construction. Somewhere in the battery's specification is the amp-hour rating. For AA size batteries, it is common to use milliampere-hour ratings (mAH). You need to multiply the mAH rating by 1.5 if you're figuring alkaline batteries, or 1.2 if you're figuring rechargeable batteries. Then divide the result by 1000 to get watt hours. Nicad cells are typically rated 500 to 1000 mAH. NiMh batteries typically have twice the rating of similarly sized nicad batteries. Alkaline batteries are typically rated at 2500-3000 mAH

What are the benefits of using a NiMh battery instead of an alkaline battery?

NiMh batteries perform better in high discharge devices (like digital cameras) than alkaline batteries. They are also rechargeable, unlike alkaline batteries.

Can you use a rechargeable NiMH battery in a wireless mouse?

yesYou can use a NiMH battery in just about any application you would use a normal alkaline battery. However, NiMH batteries do not perform well in low energy applications - they are designed for use in high energy devices like digital cameras. For things like clocks, standard alkaline batteries are better suited.In my personal experience, the NiMH and NiCd batteries did not perform as well in my wireless LASER mouse. Alkaline batteries performed a whole lot better. The problem is that NiMH and NiCd have relatively high "self discharge" rates; that is, while they are not in use, they will loose their charge over a fairly short time as opposed to alkaline batteries which loose their charge at a much smaller rate and over a much, much longer period. Also of consideration is the fact that rechargeables (NiMH & NiCd) produce 1.2v at full charge (NiMH can achieve 1.4v, but for very short time) whereas alkaline batteries are 1.5v. This 0.3v can be a problem with some electronic devices. 9V rechargeables only deliver 7.2v.

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.


What is the life of a NiMH AAA Batteries?

A set of NiMH AAA batteries can last roughly a month on a full charge if they are not being used at all and are simply allowed to sit around. In devices such as cameras and small pda's where rechargeable batteries are best used, the batteries can last nearly as long as normal alkaline batteries on a full charge. Exact times depend on the capacities of the NiMH batteries. A charge lasts long enough for a camera to be used normally for several days and hundreds of shots. As long as the NiMH batteries are not allowed to be idle and self-discharge, the life of a single charge is almost as long as a full alkaline battery. The life of the battery itself can easily be several years. NiMH batteries don't need much maintaining and can last for hundreds of charge cycles.

Your camera insists to use nimh AA batteries can you use nicd batteries?

yes. NiMH batteries and chargers are easier to come by though. Alot of times, the mAh will be higher in the NiMH batteries as well...so there is really no point to using NiCD unless you'd prefer it.


Is it OK to mix NIMH and NiCd batteries in an electronic device?

You should NEVER mix different types of batteries in any device. The charging characteristics are different and one type will charge "harder" than the other.
