i dont recall seeing them in a while, but man those were cool

alot of batteries now have them on the battery.

My car keeps draining batteries like crazy. Dealer can't fix it and it's not worth spending too much money on an old car. My solution is to connect a second battery (stationed in the trunk) via wires to the actual battery in the car and put a switch somewhere on my dashboard so that when I need to turn the car on i can switch the trunk battery on and basically jump the car without taking out the jumper cables. Does anyone know what specifications the wire and/or the switch need to work best with the 12V car battery? Or any switch with an On/Off position will do? What about the cable? Is any material better than others? Any help will be appreciated!

what kind of car?
did you check the battery?
did you check the alternator?
did you check the regulator and diodes?
anyone check for a short or open circuit?

I just got one today and it came with 2 Sony AA batteries but the batteries only lasted for a few good long hours. Then I tried to use some batteries that I bought a cheap dollar store and the batteries only lasted a few minutes and when I tried to take certain pictures with the ISO opition, the camera switched off. Whats the best kind of batteries I should use for this camera cause I really like using it.

I use Duracell NiMH 2600mAh batteries and they work great in my DSC-W1.

The laser printer’s cartridges are more expensive then the cost of inkjet printer’s toner. However they do last longer especially if you remember to set the printer in black and white printing mode when printing black and white and only using the color mode when it is really needed. Another way to make an expensive color laser toner cartridge last longer is to keep the printer in low quality mode unless you are printing out the final document.

There are very few disadvantages to owning a laser printer in general but one of them is definitely the cost. The money that you could spend on a very high-end inkjet printer will only buy you a very low-end color laser printer with limited capacities. Color laser printers with multi-functions such as a copier and a fax all in one are even more expensive. However a middle of the line black and white laser printer is comparable to the price of a top of the line color inkjet printer.

Another disadvantage is the cost of the cartridges inside a laser printer. Sometimes the cartridges cost almost as much as the printer did which is why many people throw the entire printer out and buy a new one after the cartridge expires in year or two.

If you live in a hot or humid climate a laser printer may not be the ideal solution for you. This is because running these machines can make a room very hot. The fuser inside them, which is the device that melts the plastic granules that constitute the powder that makes up the toner onto the paper, heats up to as high as 200 degrees Celsius.

Another limitation of a laser printer is that they only really print on certain kinds of paper. If you want to print out photographs then a laser printer is not for you as they are not yet capable of printing high-resolution images. Also you cannot put photographic paper through a laser printer. For the best quality images you need to buy a bubble jet ink printer that can transfer an image onto photographic paper. The color quality that you get with a bubble jet ink printer is just as good if not better than the color quality that you can obtain with a laser printer. A high-end color printer that produces quality color images can cost as much as $3,500 to $10,000 whereas you can get a good quality ink jet printer for about $200.

Another disadvantage of laser printers is that many of them are limited by the amount of memory that they are sold with. This can sometimes limit the number of fonts that you can use. To expand the memory of your color laser printer you usually have to buy a small RAM board. This is the only reliable way to install memory so that the color laser printer can utilize a number of fonts.

The more expensive a laser printer is the faster it is. The affordable models only print out about four pages a minute. Top end models print out about twelve pages a minute but they are not really affordable for the individual.

Laser printers, especially the color laser printers, can also be heavy and take up a lot of desk space or room in the office. At the time of writing there was also no such thing as a portable laser printer. The reason that a portable laser printer has yet to be invented is because a battery does not yet exist that is small enough to provide laser printer functions with enough power so that it can be taken on the road.

If you think solar power and solar batteries aren’t the wave of the future, you may be missing out on some exciting possibilities. America is just now starting to take action in the way of policy changes and R&D funding to move away from energy produced from fossil fuels. On August 21st 2006, Governor Schwarzenegger signed the solar power bill that aims to make California the biggest producer of solar energy in the world by 2018 through the installation of 1 million rooftop solar batteries on residential homes, office buildings schools and farms.

Homeowners who outfit their homes with solar batteries will not only benefit from lower energy use costs and higher home resale value, but under Schwarzenegger’s new law, they can sell excess power back to their utility company for a profit. Despite all of the evidence pointing to the positive aspects of power generated through solar batteries, including a commitment of $2.9 billion dollar commitment by the California Public Utilities Commission, many people still believe that solar batteries are ineffective for producing adequate power. In this article, we will explore the 3 most common misconceptions and facts surrounding home solar power and the solar battery.

Misconception #1 – I would need to live in a hot area of the country in order to benefit from a solar battery
There are two types of solar panels. One produces heat by absorbing heat from the sun. The other type, solar batteries, use Photovoltaic principles to turn the light from the sun into energy. These solar batteries are made of silicon which becomes electrically charged from the sunlight. The sun is always shining, even in the wintertime which means that solar batteries work year round-even when it doesn’t feel hot outside.

Misconception #2 – Using a solar battery will not make that much of an impact on the environment
Unless you believe that reducing greenhouse gasses by 3 million tons for every 1 million homes equip with solar panels isn’t a big impact, this misconception is simply untrue. The removal of 3 million tons of greenhouse gasses is roughly the equivalent of eliminating the harmful greenhouse gas emissions of 1 million cars. Multiply this by the total number of homes and residences in the US, and the impact is critical move for a growing population.

Misconception #3- Solar batteries cost more than they save
While it is true that solar batteries do involve more upfront costs than simply plugging into the grid, it’s important to look at costs over the long term to get an accurate cost perspective. Solar batteries can continue to produce power steadily for 50 or more years. Once your batteries are installed and producing power, there are no more costs involved with taking energy from the grid. And while grid energy may be affordable now, that doesn’t necessarily mean that it will be in the future. We have seen how quickly a limited supply and demand can impact the cost of gasoline.

What’s more, if the rest of the US follows California’s lead, excess electricity can be sold back to the energy for a profit. Solar batteries also open up new possibilities in home ownership; allowing people to build private getaways and vacation homes in remote, low land cost areas that are off the power grid. With the increased longevity and lower cost of today’s solar batteries, homeowners owe it to themselves to explore the possibilities of solar power and to rethink their paradigms about energy costs and homebuilding possibilities.

I want to buy a battery tester so that I can ensure my rechargeables have a decent charge before putting them in a device such as an MP3 player, TV/DVD remote control, or digital camera. Right now the only way I have to test the charge is to put them in the device and see if the device fails to power on. Obviously, this is not a good option, especially when using the camera to capture my toddler's developmental milestones (as well as her megawatt smile!).
I basically want to know what features are necessary and which ones are "nice to have". I don't want to spend an inordinate amount, given the current price of gasoline.

What test are you going to do?
Charge/discharge?

Look for the tester with timers and loggers. They can log the battery voltages over time.

I have Nissan Sentra 2002. I recently had my battery changed. The new battery died after few days. I went back to the shop and they put a new battery. The new battery died again. I went back again to the shop and now they are telling me that my car has electrical problem that drawn the battery down. My car has no problem before I got the battery changed. So I am wondering if a mechanical mistake in changing the battery can cause electrical problem.

Only if done while battery in car, and still connected to your system.

I am trying to solder 4 1.2V NiMH batteries together end to end to make a battery stick. What is the best way to do this? I tried melting the solder with the soldering iron on one battery and then trying to jam the other battery on real quick, but this was a horrible failure. Do i need a different tip, or solder, or any suggestions welcome.

Solder won't adhere well to the coating on battery terminals. Remove the coating with sandpaper and use wires to make the joint. I cannot see you will do what you are trying by sticking them together.

Be careful not to over heat it.

tRY LOOKING AT TRUCK STOPS I USED TO WORK IN 1 IN MELB AND THEY HAD A VARIETY OF ACCESORIES THERE

Do you know what type of battery is used for the i Robot Roomba 405 and where i can buy one?. If possible can you give me a link of a place selling it so i could buy one? (just bought the robot vacume from ebay really cheap but it has no battery or virtual walls)
Thanks. All answers will be appreciated.

This battery is built in according to Home shopping! You may check with them to see if you can purchase it alone but I think your outta luck!
