I need to be able to take the evidence from a battery leak of D batteries and determine if it was Alkaline or Zinc-carbon batteries that were installed. The leak was wet and gooey, and the contacts on the device it were in were also damaged. Are there any particular signs and determining evidence to look for to differentiate the two?

Potassium hydroxide leaks from Alkaline batteries and form a feathery crystalline structure…. check the "leak" section of this wikipedia page:

http://en.wikipedia.org/wiki/Alkaline_battery

I would call or bring the device to Batteries Plus… They should be able to tell you for sure.

Batteries Plus phone number is: 1.800.677.8278

I do this constantly: When I am watching videos or doing something that can drain my laptop’s battery really fast, i take out the batery and leave the laptop connected. Is this good or bad?

it’s the best! assuming you’re not working on anything (that needs to be constantly saved), it’s the best for the battery.

I have 2 12" Kicker Comps with a Kicker 500 Watt Mono Amp. My battery drains and makes my start up on my truck lag and i have to give it gas in order for it to start up. Should I get another battery, alternator, or better battery like a optima. I have a duralast yellow top right now.

That setup should not be draining your battery that much, i would check for shorts somewhere. Also, if the battery is old i would replace it before doing something more expensive like changing your alternator. Take the battery to you local auto parts store, they will tell you if its still good.

I was planning to get a battery pack and charger for my xbox 360 controllers but I was wondering if it’s worth and what the battery life is, or if it’s better to just get a battery charger and rechargeable AA batteries.

dont use those. get a battery charger and some duracell nimh rechargeable batteries 2000mah and up. you wont regret it.

We have put a charger on the car and the charge holds while the car is off. But when driving the car the battery drains in less than an hour. The alternator has been tested and shows to be good. The new battery has been tested and shows to be good. The head connectors for the battery have been changed. The problem is still occurring. What could the problem be?

You almost answered your own question. The fact of the matter is the battery is draining because of *lack of voltage. And what provides your battery with a re-charge of voltage? Your alternator.

How did they test it and what did they tell you? It’s pretty obvious it’s not charging between 13.5 - 14.0 volts with the engine running. Essentially the battery is used for starting, playing the radio with the engine off for a short period of time and four way-flasher use in emergencies. The alternator on the otherhand provides amperage to every electrical circuit in the car when the engine is running.

Here are some tips to maximize the <a href=”http://www.ipodenergy.com”> iPod’s battery </a> power so that long lasting:

1.  IPod batteries work best at room temperature (about 20 degrees Celsius), although in general can be used in temperature between 0-35 degrees Celsius. If you leave in place accidental cold, let down temperature as temperatures room before turn it on.
2.  Do not wait until your battery runs out to refill. Although not currently used, the iPod still eat the flow of electricity from the battery even though very small. This is what causes the battery is slowly become empty. iPod if you rarely use, recharge the batteries at least once every three weeks.
3.  Make sure your iPod have the latest software updates from Apple.
4.  If not used, always switch the button to slide the iPod Hold position to prevent the oppressive control the iPod accidentally.
5.  Do not use features backlight on the iPod, turn off the feature. You can set the live time through the options [Settings] > [Backlight Timer].
6.  IPod battery is made of Lithium Polymer, which has about 500 charging cycle times, too often do not refill the batteries. Should, or must first cover the additional chassis before charging the iPod.
7.  Make the album or a play list, and play music from there. The reason, if you frequently play the new tracks are not stored in the cache of the iPod, the iPod hard disk must revolve access to the song. The more often rotates, the larger the energy the batteries used.
8.  When the iPod is not used, disconnect the jack of headset.
9.  Save compression formats like MP3 and AAC on the iPod. Avoid file AIFF or WAV have a certain size that is not compressed and large. The format is indeed produce good quality sound, but the iPod’s hard drive must work harder to play. For information, the iPod’s cache works most efficiently with songs that the size of less than 9MB.
10. Use iPod regularly so that the electron-electron in Lithium batteries continues to move on.
11. Adding features EQ (Equalizer) to the playback will take a lot of power your iPod. Just turn off the feature when not needed. But if you want to add EQ to the track in itunes, make sure your EQ to save option [Flat] to turn it off.

These are the things that you need to remember about saving battery power in your iPod. By following these tips, you can be sure that you will be able to prolong your iPod’s battery life.

Now that you’ve known the other car care basics, perhaps it’s time we take a look at the fluid essentials that are literally the life giving blood of your car.

1. Brake Fluid- Is a type of hydraulic fluid that is used in hydraulic brake applications of your car, motorcycles and trucks. This type of fluid is used to transfer force under pressure from its point of origin among hydraulic lines to the braking mechanism close to the wheels.

Most brake fluids today are composed of glycol-ether but several types with mineral oil and silicone composites are also out in the market. This type of fluid should meet stringent requirements set by organizations such as SAE and the US Department of Transportation (DOT) - hence you get ratings on labels such as SAE or DOT 3 and 4 compliance.

As a rule of thumb, brake fluid should always be replenished if the levels in its container decrease with every drive. Fluid level in the master cyclinder will drop as the linings, brake pads and shoes wear and the calipers extend further to compensate. Brake fluid level may also be low because of leaking, which can lead to loss of hydraulic pressure and the most dangerous- brake loss.

It is very important to constantly monitor your brake fluid levels to ensure safe driving and fill according to the set level. Flush and change your brake fluid every 1-2 years to further ensure reliability and take note to never mix brake fluids with different DOT ratings as this can result to poor fluid performance.

2. Power Steering – Is another type of hydraulic fluid that transmits the power steering system of cars, trucks and other modes of transportation.
This is the fluid that guards your power-steering pump and rack from wear and tear. It requires constant monitoring and refilling from time to time according to the required level in its cylinder.

A way to notice that your steering system is about to have a problem or that your power steering fluid is running low is when you turn the steering wheel and you hear whining noises. Have your car checked when this occurs to prevent serious damages to your power- steering system.

Note: There are products out in the market today that contain the combined properties of Power Steering and Automatic Transmission Fluids (ATF). Use any of these products to save and be protected more.

3. Battery Fluid- Is the electrolyte fluid found inside the cells of your battery. If you are using the regular type of battery and not the maintenance free one, then you are required to refill your battery cells from time to time with electrolyte fluid.

Standard battery for cars is 12V and usually has 6 individual cells inside it. To refill, simply remove the vent caps that can either be found on top or on the sides of the battery. Check and fill the electrolyte fluid inside.

Note: There are some brands of maintenance free batteries out in the market today that can run on dual power- meaning they also have vent caps for electrolyte fluids in case their power supply run out. Although this type of battery may not come cheap, it would be best for you to use it.

4. Radiator Coolant- Is a mixture of anti-freeze fluid and water designed to protect the radiator and cooling system all year round. Using one will protect your engine from overheating. Most coolant products out in the market today come with various additives that can further help you against rust and other forms of corrosion, lubricate or increase the cooling efficiency of your cooling system.

Simply pour out the contents of your coolant to the radiator reservoir. Add water to the set level and you’re done.

For maintenance, it is very important for you to drain and flush your coolant once a year (or depending on the product recommendations) and replace it with a new one.

Note: Never mix different types of coolant together as this can lead to damage or a reduction of your car’s cooling system. Before changing to another brand, be sure to drain and flush your cooling system of the old one.
See to it that the reservoirs of these fluids are in constant levels and refill when they’re not enough. Properly maintaining them will help ensure your safety and prolong the life of your car.

Buckle up and drive safely.

Tips to extend the life of notebook battery

There are many kinds of notebook battery,different types of batteries will certainly not the same.Now lithium-ion battery commonly used in laptop or similar products.Shortly before personal computers, A4-based notebook computers in the temporary use of the premise of using a nickel-metal hydride battery.Until the mid-nineties, using a nickel cadmium batteries.After the user has bought the notebook,first please read the operation manual,to confirm what kind of the battery,if does not have the instruction booklet,we can check the battery specifications through the home page of the notebook company.

The “memory effect” is the biggest problem of nickel-hydrogen batteries and nickel-cadmium batterie,if the battery has not run out on charge. When next time using the battery,there will be no power on that place started to charge.If circulates this process unceasingly,the battery’s life will become shorter and shorter.

Although the “momory effect” of  Ni-MH battery is smaller than nickel-cadmium battery,but the half-way charge repeated is  the reasons for shortening the life of battery.So please try to be all used up the battery before recharge.

Lithium-ion battery without the “memory effect”, so even the off half-way charging there will not be  too much a problem.

The method to extend the battery’s life.

Although the lithium-ion battery without “memory effect”, but improper use will greatly affect life expectancy. When use a lithium-ion battery should pay attention to the following points:

1,Fully charged state not to use AC power | Regulators drive;

2,Using the energy saving features;

3,Fully discharge once every few months;

4,Unplug the AC adapter,when the notebook not in use in a long period of time
