Everyone knows that at times are silly or light-hearted, but you will find others which serve an essential purpose. Check Your Batteries Day is certainly highly suggested since it could really save your valuable existence.Produced to boost understanding of the significance of testing and getting working batteries in household home appliances like smoke sensors and deadly carbon monoxide sensors. These products assistance to warn you of the potentially existence threatening situation, providing you with vital time for you to grab yourself and your loved ones to safety. However, it’s important they're examined (usually this can be done by pushing a control button) regularly to make sure they’re working properly. Check Your Batteries Day is really a indication to complete exactly that.While you’re within the routine of checking, it’s smart to check other household home appliances, for example controllers, toys, clocks along with other electrical products. Should you not have spare batteries available, consider purchasing some.

As mentioned, there are two batteries in the car, the large, high-voltage traction pack and the small, 12v auxiliary battery. The original 12v batteries usually only last 3-6 years so yours did quite nicely if it's original.

The 12v aux battery is the one responsible for turning the car on. It can often be completely fine one day and then not have enough current to boot up the car the next. The Prius takes much less current to boot up than a conventional car does to start, so the 12v battery can be barely hanging on for months and still boot the car...until one day it won't.

Having the 12v battery replaced at the dealership is pretty expensive (as you noticed). If you run into this again, a popular replacement is the Optima Yellow Top part # DS46B24R. It tends to have a longer service life in Prii than the original style 12v battery and better withstands accidental draw-down, such as when interior lights are left on. You can replace the 12v battery yourself...here's a how-to video:

It is possible to check the voltage on the 12v battery by not taking anything apart, by either measuring across the jump-start terminal under the hood or by following a procedure to enter a check mode on the center display (multi-function display), but service departments may or may not check it when the car is in for service.

A lot of the original 12v aux batteries are AGM (advanced glass mat), I recently learned, and not a flooded lead-acid (although a few lead-acids did make their way into the cars at the factory--mine had one). They're not the greatest batteries though, and their service life isn't overly long. There are better replacements.

Iphone 3 battery drainage?

1.Turn down screen brightness

2.Adjust email to check for email less often

3.Turn off WiFi

4.Turn on auto-lock for the screen

5.Turn off the equalizer

6.Get an external battery

7.Get a mobile charger

8.Turn off vibration alerts

9.Turn off Bluetooth

10.Update the phone often

1. Turn on Auto-Brightness

The iPhone has an ambient light sensor that adjusts the brightness of the screen based on the light around it. Turn this feature on and you’ll save battery because your screen will need to use less power in bright places.

2. Use programs with 3D less often.

Not surprisingly, I’ve noticed that when I play games rendering 3D, battery life drops. Using the graphics chips more intensely will crank up power usage, but maybe the drain is also because of the nature of gaming

3. Reduce Screen Brightness

Users can control the default brightness of the screen. Needless to say, the brighter the default setting for the screen, the more battery it requires. Keep the screen dimmer to conserve more of your battery.

Find it in Settings -> Brightness

4. Turn Bluetooth Off

Bluetooth wireless networking is especially useful for cell phone users with wireless headsets or earpieces. But transmitting data wireless takes battery and leaving Bluetooth on to accept incoming data at all times requires even more juice. Turn off Bluetooth except when you’re using it to squeeze more juice from your battery.

5. Turn Off 3G

The iPhone 3G and later models operate on two cellular networks, EDGE and the faster 3G. Not surprisingly, using 3G requires more battery life to get the quicker speeds and higher-quality calls. It’s tough to go slower, but if you need more battery, turn off 3G and just use EDGE. Your battery will last longer (though you’ll need it when you’re downloading websites more slowly!).

6. Keep WiFi Off

The other kind of high-speed network that the iPhone can connect to is WiFi. WiFi is even faster than 3G, though it’s only available where there’s a hotspot, not virtually everywhere like 3G. Keeping WiFi turned on at all times in hopes that an open hotspot will appear is a sure way to drain your battery life. So, unless you’re using WiFi right this second, keep it turned off.

7. Turn Off Location Services

One of the coolest features of the iPhone 3G is its built-in GPS. This allows your phone to know where you are and give your exact driving directions, give that information to apps that help you find restaurants, and more. But, like any service that sends data over a network, it needs battery to work. If you’re not using Location Services, and don’t plan to right away, turn them off and save some power.

8. Turn Data Push Off

The iPhone 3G can be set to automatically suck email and other data down to it or, for some kinds of accounts, have the data pushed out to it whenever new data becomes available. You’re probably realized by now that accessing wireless networks costs you battery life, so turning push off will extend your battery’s life. With push off, you’ll need to set your email to check periodically or do it manually

9. Fetch Email Less Often

The less your phone needs to access a network, the less battery is used. So, set your phone to check your email accounts less often. Try checking every hour or, if you’re really serious about saving battery, manually. Manual checks means you’ll never just have email waiting for you on your phone, but you’ll also stave off the red battery icon.

10. Auto-Lock Sooner

You can set your iPhone to automatically go to sleep – also known as Auto-Lock – after a certain amount of time. The sooner it sleeps, the less power is used to run the screen or other services. Try setting Auto-Lock to 1 or 2 minutes.

11. Do Less Battery-Intensive Things

Not all ways to save battery life involve settings. Some of them involve the way you use the phone. Things that require the phone be on for long periods of time, or use a lot of system resources, suck the most battery. These things include movies, games, and browsing the web. If you need to conserve battery, limit your use of battery-intensive apps.

12. Sleep and Wake Less

Constantly putting your phone to sleep and waking it up will drain battery life. Of course these functions are common parts of using the phone, but you can also be judicious in your turning on and off of the phone and save battery life at the same time.

13. Buy an Extended Life Battery

If all else fails, just get more battery. A few accessory makers offer extended life batteries for the iPhone. If you need so much battery life that none of these tips help you enough, an extended life battery is your best bet. With one, you’ll get days more standby time and many hours more use.

14. Turn off Vibrate in Games

Playing a game with vibrate happening frequently is an unnecessary battery suck. If you can turn it off, turn it off.

Battery, alternator or other?

Check battery connections and wires. Also check opposite ends of those wires for a solid connection. The large diameter (usually red) positive wire/cable would go to starter and the large diameter (usually black) negative wire/cable to ground on body/frame of vehicle or engine. Some of the cables have smaller diameter wires splitting off of them as well.

Be extremely careful with a side mounted battery post as they break easily.

Tools needed: old toothbrush, used butter tub (or similar), a wrench, acorn shaped battery cleaner tool and battery tester/volt meter/multimeter.

Battery voltage should be above 12 volts with engine off. Slightly higher (up to 14v) if engine running. You can get a cheap ($15-20) battery tester/voltmeter from a place like Radioshack or an auto parts place.

If you remove battery connectors, be sure to remove negative cable (- ) first, then positive ( +). You may loose some preset memory on your stereo though. Install in reverse. If connectors are stubborn there is a tool available to pry up the connector without causing damage to battery posts.

If there is a foamy or crusty look to any component on top of the battery, then clean with a old toothbrush and solution of 1/4 cup baking soda and 8 oz water in a clean old butter tub (a can of coke works in a pinch, but messy) you need to rinse with water also. You can also buy some battery cleaner chemical at the auto parts place.

A more intensive cleaning would be with a acorn shaped battery wire brush tool to clean out inside ring of battery connector and top terminal on battery - its cheap.

If battery wire/cables copper strands are greenish, loose, frayed and separated ends or if the cables have a crunchy or hardened feel to them, then corrosion may have deteriorated the cables amperage carrying ability. The entire length of the battery cable assembly should be replaced in this case.

If top of battery is cracked or oozing then it should be warrantied or replaced.

If after a good cleaning and replacing any suspect wires/cables or battery, the next step would be to check the alternator and/or starter.

Autozone and some other parts places offer a free diagnostic check of battery, starter and charging system on your vehicle. They may also have equipment to check these off your vehicle.

Also a worst case scenario could bean ignition issue or the ECU (cars computer) is on the fritz.
