Rechargeable Batteries & mAh: What a Higher mAh Means For Your Digital Camera

Sanyo Eneloop AA Rechargeable BatteriesWhen researching rechargeable batteries, the term “mAh” gets bandied about quite often. Read about how a higher mAh can have a tremendous impact on the performance of electronics like digital cameras.

Anyone who owns a digital camera — particularly one that takes AA batteries as its power supply — knows that they have the capacity to suck battery power like a vampire. It is not uncommon for a digital camera to completely drain its batteries after just an hour of heavy use, which often comes at the most inopportune times, leaving you with no digital camera when you need it the most.

If you rely on AA rechargeable batteries for your digital cameras, then the most important consideration is investing in rechargeable batteries with the right mAh. Of course, if you have no idea what mAh is, then it might be a bit confusing to determine what level of mAh you need for digital camera, and why.

Rechargeable Batteries and mAh

“mAh” stands for “milliampere-hour.” But if that definition is somewhat lost on you, then think of it another way: mAh is all about battery capacity — kind of like the size of the petrol tank on your AA rechargeable batteries. So, it is easy to imagine that the higher the mAh on your AA rechargeable batteries, the higher performance for your digital camera.

However, it can be particularly helpful in understanding the battery draw of your digital camera when you go shopping for rechargeable batteries, and determining if you’ve got the capacity you need for the kind of camera and picture taking you normally engage in.

What Components on a Digital Camera Use the Most Power?

Simply put, there is no set answer to this question, since digital camera features vary from model to model, and depending on the performance level of the digital camera, you’ll need to take that into consideration when shopping for rechargeable batteries. The good news is that, for the vast majority of digital cameras, they draw very little power when simply turned on — most cameras have idle currents of 1 mA.

However, it is all the “bells and whistles” on a digital camera that start to push the levels of power that drain rechargeable batteries. Actions like encoding a JPEG, manipulating sensor data, driving the LCD screen, or charging the flash, all draw high currents. And considering that these are commonplace operations on all digital cameras, you can begin to imagine why your rechargeable batteries drain so easily.

Let’s go back to the definition of “mAh,” and hot it relates to your digital camera’s performance. Think of it this way: if the rating of your rechargeable batteries is 2500 mAh, then you can draw 100 milliamps for 25 hours, or 50 milliamps for 50 hours etc. When you think of your digital camera “idling,” then you’d imagine that you could get a lot of endurance out of rechargeable batteries rated at 2500 mAh. However, this would only be when a camera is  in standby mode. When you’re running all of your camera’s components, it is more realistic to pull about 200 mAh, and when you take a picture, it can draw anywhere between 1.2 and 2A!

The best approach is to invest in the highest mAh possible for your digital camera’s rechargeable batteries. Vapex’s 2500 mAh instant rechargeable batteries are a great value, and come pre-charged. Sanyo Eneloop‘s pre-charged AA rechargeable batteries are rated a bit lower at 2300 mAh and priced a bit higher, but their production quality can make up for the slightly lower rating, with Sanyo Eneloop claiming their AA’s can take up to 500 photos.

Sanyo Recharges the Eneloop: What You Need to Know

sanyo eneloop nimh rechargeable batteriesSanyo continues to recreate the revolutionary Eneloop rechargeable battery.

From its beginnings, the Sanyo Eneloop was revolutionary because it was one of the first NiMH rechargeable batteries that came charged right out of the packaging, making it ready to use immediately after purchasing it. It also lasted longer than other lackluster battery brands on the market, making it the first truely “premium” rechargeable battery brand/

The all new Sanyo Eneloop is now even stronger and lasts even longer — it is now rechargeable up to 1500 times. To top that, the Eneloop can be stored for three long years and they’ll still retain 75% of its capacity. You can even use Sanyo Eneloops in freezing cold temperatures.

Now for the technical aspects; The Mignon-eneloop (AA) has a 2000 mAh capacity and the Micro-eneloop (AAA) has an 800 mAh capacity. For all the green, tree-saving rechargeable battery users out there, these batteries are factory pre-charged using solar energy in Japan using photovoltaic generation. This gives the eco warriors of the world an added incentive to invest in Sanyo Eneloop: even the charge on these instant rechargeable batteries do not contribute to the world’s “carbon footprint.”

In addition, the Sanyo Eneloop is the most cost-effective rechargeable battery design for the average consumer to use compared to other NIMH rechargeable batteries. Not only is it more powerful, but it is also much more cost efficient. With normal alkaline batteries, you have to replace them every other couple months. The Eneloop can last for up to ten years! Now for me, I’d rather pay a few more dollars to get rechargeable batteries that I won’t need to swap out every month. Each time you charge your Eneloop batteries, it only costs 4 cents.

Sanyo Eneloop Update: Eneloop Pro Coming To Australia?

sanyo eneloopJapanese and American companies have often seemed to treat Japan as a huge testing ground for their products. This is because in many ways, as Japan goes, so goes the world. Sales in Japan can often accurately depict sales in Europe, North American, and even Australia. The newest product that is getting tried in the land of the rising sun is the new line of Sanyo Eneloop batteries. Will it be a worldwide hit, or will it never see its way to Australia except through imports?

Sanyo Eneloop or Generic-brand Rechargeable Batteries? Here’s How To Decide

Sanyo Eneloop rechargeable batteriesEven in the world of rechargeable batteries, comparison shopping can be extremely difficult. The market is saturated with underpriced, underpowered, and downright dangerous rechargeable batteries. However, even among the high quality batteries, choosing the right one can be nothing more than trial and error. Naturally, all rechargeable batteries are not all created equal. Some will operate better for heavy draw devices that require large amounts of power delivered quickly. Some will work better for long life, able to produce lesser amounts of power over long periods of time. Some will be preferable for creating your own battery packs to save money. Some are better for the environment, and some have a greater shelf life which makes them much better choices for placement in emergency gear.

Really, when it comes to rechargeable batteries, there are two primary choices: the Sanyo Eneloop and the Vapex line of batteries. The Eneloop works better for devices with a higher energy demand on the battery, while the Vapex batteries are far more economical, costing a fraction of the price of the Eneloop, so they are preferred by anyone looking for a bargain.

Battery Chargers and Inductive Charging, Together at Last?

battery charger - Panasonic ChargepadBattery charging has lately taken a turn for the bizarre. Panasonic has announced that they intend to use the proprietary technology they acquired when they purchased Sanyo to make a wireless battery charger that doesn’t charge batteries. Instead, the device will charge nothing but other battery chargers.

The device will be known as the Panasonic Chargepad and is scheduled to be released in Japan on June 24th. Since the purchase of Sanyo by Panasonic, the resultant company, now united under the umbrella of Panasonic’s name, has become one of the premier manufacturers of rechargeable technology, mainly focused on providing rechargeable batteries for fuel-efficient cars. The Chargepad shows a desire by Panasonic to expand in the area of mobile electronics. The Chargepad will utilize the same basic technological principle as Sanyo’s Eneloop. Panasonic hopes that the new device will open up a new market, as well as a new way to charge batteries for cellular phones and eventually laptops and tablet PC’s.

It is a useful idea for those that are constantly on the move. The target user will be a person that is never at rest during their day, but still needs their mobile devices as they go from one place to another, never really able to stop long enough to fully charge their batteries, or even their battery chargers. The Chargepad works for these individuals because it never has to be plugged in, and works fully wirelessly.

The way this is accomplished is through the same technology that has been seen before in items like the Wildcharger or the Powermat. It is a technological marvel called Inductive Charging. The concept behind Inductive Charging is that it doesn’t require a direct current (aka conductive charging or direct coupling), but rather utilizes an inductive coil located within the device to generate an electromagnetic field. Inductive charging then uses this field to generate electricity that is then moved to the battery, or in the case of the Chargepad, the battery charger.

What makes this more useful than previous chargers is the Chargepad would not focus entirely on the battery alone. Instead, in charging the battery charger rather than charging the battery principally, the charger can be charged while the individual is in motion, keeping the battery in the device as the charger builds up its charge. The charger can transfer power to the battery more efficiently than the Chargepad could by itself, limiting the turnaround charge time for the battery once it is placed in the charger. While that doesn’t seem like an enormous loss, anyone that doesn’t have the time to alternate batteries would still be losing a charge, while with the Chargepad there would be a serious reduction in downtime between charges, because of the redundancy system in place between pad and charger, and then charger and battery. It is essentially a failsafe system.

To many westerners, the oddity of the Chargepad is the most obvious: a charger that charges chargers – which in turn charges batteries – seems asinine. At what point does this become an MC Escher drawing? What about the charger that charges the Chargepad and so on backwards? The possibility for comic surrealism is endless.

This concept probably won’t appeal to many people in the western hemisphere, as the larger land masses dictate that most individuals on the move will not be removed from their cars or outlets for heavily extended periods of time. In Japan, the idea is elegant. It takes into account that many people that conduct business in Japan are constantly on foot or public transportation, areas where charging is difficult, if not impossible. The mobile businessman is common in the hustling society, with land constraints making cars uncommon and inconvenient. For those out of the office all day, which is constantly increasing in number, they don’t have the time to charge, but need to always be in with clients, customers, or employees.

The other drawback of the Chargepad is that while induction chargers might be useful while on the run, they do not provide nearly the same level of charge that can be found from direct AC power. To achieve fast, complete charging, mobile components and batteries still need more than just a power pad. They can be charged to usability, and can keep you on the road, but the technology of induction chargers will never compare to good, old-fashioned metal on metal contact to provide the best power, especially if you want it to charge quickly. Even Electronics Warehouse, experts in the area of emergent battery technologies have found flaws in induction charging technologies. While the future might hold something greater, induction chargers are still the homely cousin of direct charging.

Currently the slated cost of the device upon release will be 8,894 to 10,511 Yen, which equates to approximately $104 to $123 AUD. The projected release in Australia is mostly dependent on sales in Japan, but it will likely have a niche release, marketed to people in heavily urbanized areas where public transportation is much more common. That is, if Panasonic decides to market it outside of Japan at all.

Currently the Chargepad only works with a few specific charger models, namely the 2,700mAh model QE-PL101-W and the 5,400mAh model QE-PL201-W. However, in the center of the Chargepad is the qi logo, an inductive charging standard that indicates the Chargepad may be useful for a much wider variety of devices in the future, and may help set the standard for future wireless devices to bring qi technology to the world.

The Chargepad is a good idea, and certainly helps anyone that likes to be unbound to their cords and wires. It is mostly a jumping off point for future uses of both inductive charging as well as qi technology which may help to allow future mobile technology to be un-tethered by wires and outlets. While charging chargers instead of charging batteries is an interesting way to go, it veers off in another direction from its Eneloop predecessors, which gives it a special edge. While it certainly might turn a few heads and raise a few eyebrows, it is doubtful that it will be the final word in mobile charging, but many chargers designed in the future will probably owe their lives to the way the Chargepad is changing the way many companies think about their batteries.
