What is the difference between mah and nimh batteries

While this may be true under certain circumstances, the difference is not relevant when considering power sources for electronic devices like digital cameras or portable music players.

If you are choosing a battery to drive a high torque power screwdriver, then NiCds can outperform NiMH. NiMH batteries require more sophisticated chargers than those typically used for NiCd batteries. But smart chargers designed especially for NiMH batteries are now readily available. Unfortunately, it is. Digital cameras use alkaline batteries at a shockingly fast rate.

For an explanation why, see the following question. If you are using lots of alkaline batteries for your electronic devices you'll probably want to switch to rechargeable NiMH batteries ASAP. Not only will the NiMH batteries power a digital camera or most other electronic devices much longer than alkaline batteries will, but they are much less expensive to use. Alkaline batteries were not designed to meet the very high power demands of today's electronic devices. Alkaline batteries have a high rated capacity, but they can only deliver their full capacity if the power is used slowly.

See alkaline drain chart. Electronic devices such as digital cameras place a high power drain on batteries, so it is much better to use rechargeable NiMH or NiCd batteries for these type of devices.

Lithium ion rechargeable camera batteries also work well in high drain applications like digital cameras but can be more expensive. Do Ultra or Advanced Formula alkaline batteries last any longer than standard alkaline batteries? Yes, for high drain applications Duracell Ultra and Energizer Advanced Formula batteries do last longer than standard alkalines. So instead of lasting for say images they might last for They last much longer on a single charge and don't have to be discarded after a single use.

What about rechargeable or renewable alkaline batteries? Rechargeable alkalines work well for some uses but, they are not a good alternative for use in digital cameras. They typically have an even lower capacity than standard alkaline batteries. This means that if a standard alkaline only lasts for a few exposures, a rechargeable alkaline will last for even fewer! Can NiMH batteries be substituted for alkaline batteries even though they are only 1. Yes, for most high drain electronic applications NiMH batteries are ideal substitutes and you needn't worry about the apparent voltage differences.

Even though alkaline batteries are rated at a nominal 1. As they begin to discharge the voltage of alkaline batteries continuously drops. In fact, over the course of their discharge, alkaline batteries actually average about 1. That's very close to the 1. The main difference is that an alkaline battery starts at 1. NiMH batteries stay at about 1. There are a couple of cases where their actual voltage difference may be important to you.

In the case of a device like a radio, where a higher voltage can mean a stronger signal, a fresh alkaline battery may be more desirable - but more expensive - than a rechargeable NiMH battery. This is also true for a flashlight, which will be brighter with the initial higher voltage of alkaline cells. This minor difference may not be important to you and is probably offset by the much lower cost of operating NiMH batteries.

However, for many of the applications that we see, custom Nickel Metal Hydride NiMH battery packs are more cost effective to design and manufacture and do not come with all the potential hazards associated with lithium products. NiMH batteries have been around since the early s. The technology has been driven by its high-energy density vs NiCd and Lead Acid , being environmentally friendly, good cycle life performance, and with having a good safety and reliability record.

Most applications where there is a high-energy consumption and demand, is where NiMH battery packs excel. They are also suitable in applications as backup power source, where the NiMH batteries have a BMS in order to control the charging and discharging to improve the lifetime of the battery pack.

However, using very cost effective BMS technology from manufacturers such as Texas Instruments, Analog Devices, and On Semiconductor, we can develop a system that trickle charges charge rate of less than 0. Undercharging can cause low service where overcharging can cause loss of cycle life. Most low-end chargers use rudimentary timers rather than actively monitoring the voltage to determine when to cut off the charge current. We are however unable to wrench for you, its part of the hobby so its important that you will learn that part also your self, we have great tools to sell you so just ask us what you need.

For example, a mAh battery will take longer to charge and a mAh battery. However, one should try not to pairing batteries that do not have the same mAh capacity, while charging or using, such as a mAh with a mAh, as this will result in one battery being spent faster than the other one and might lead to damage.
