Battery Regulator
Leaking NEW battery and Voltage regulator.. ?
I recently put a new battery in my 2000VW Jetta.. the car ran for about a week before my battery died due to it leaking.
I was told that the voltage regulator was most likely bad, so ordered one from the parts store, nto thinking to do a check, becasue i was frantic and need to get my car back on the road ASAP.
Im looking online and am finding no information on how to replace the VR in my car. ISome models, it (the internet) says, have them built in.. Did i just buy a part for my car that im not going to replace? Do i need to just buy an alternator? COuld it jsut be that my new battery waws FUBAR to begin with, and i dont need to replace any parts?
in case you havent noticed, i dont want to pony up for a new platernator if its not necessary.
Thanks for any advice people of the internet.
Unfortunately, your new battery failed because it was boiled by the lack of voltage regulation...Basically all of the Hydrogen was cooked out of the battery. You will need a new battery and I would highly recommend that you replace the alternator considering this is where your voltage regulator is located. Any Auto Zone or Advance Auto Parts or ORiely's will be able to test and confirm the problem and have the parts for you. Good Luck

Wet batteries are not allowed in flight. You would require to take out the batteries. Check out http://div-airline-travel.blogspot.com/ for procedure at the airport

What is the difference between Auto and Marine starting batteries.?
marine bateries are designed to be discharged and recharged over and over auto bateries are designed to deliver amperage a t start but to be maintained ( or conditioned ) while the car is running, by the alternator

Battery Power
What are some ways to save laptop battery power?
I want my laptop battery to be long lasting and not fast to have a low battery when not connected to power.
Hey,
Top 15 Ways to Extend Your Laptop’s Battery Life.Laptops tend to lose their charm quickly when you’re constantly looking for the nearest power outlet to charge up. How do you keep your battery going for as long as possible? Here are 15 easy ways to do so.
1. Defrag regularly - The faster your hard drive does its work - less demand you are going to put on the hard drive and your battery. Make your hard drive as efficient as possible by defragging it regularly. (but not while it’s on battery of course!) Mac OSX is better built to handle fragmentation so it may not be very applicable for Apple systems.
2. Dim your screen - Most laptops come with the ability to dim your laptop screen. Some even come with ways to modify CPU and cooling performance.Cut them down to the lowest level you can tolerate to squeeze out some extra battery juice.
3. Cut down on programs running in the background. Itunes, Desktop Search, etc. All these add to the CPU load and cut down battery life.Shut down everything that isn’t crucial when you’re on battery.
4. Cut down external devices - USB devices (including your mouse) & WiFi drain down your laptop battery. Remove or shut them down when not in use.It goes without saying that charging other devices (like your iPod) with your laptop when on battery is a surefire way of quickly wiping out the charge on your laptop battery.
5. Add more RAM - This will allow you to process more with the memory your laptop has, rather than relying on virtual memory. Virtual memory results in hard drive use,and is much less power efficient. Note that adding more RAM will consume more energy, so this is most applicable if you do need to run memory intensive programs which actually require heavy usage of virtual memory.
6. Run off a hard drive rather than CD/DVD - As power consuming as hard drives are, CD and DVD drives are worse. Even having one in the drive can be power consuming.They spin, taking power, even when they are not actively being used. Wherever possible, try to run on virtual drives using programs like Alcohol 120% rather than optical ones.
7. Keep the battery contacts clean: Clean your battery’s metal contacts every couple of months with a cloth moistened with rubbing alcohol. This keeps the transfer of power from your battery more efficient.
8. Take care of your battery - Exercise the Battery. Do not leave a charged battery dormant for long periods of time. Once charged, you should at least use the battery at least once every two to three weeks. Also, do not let a Li-On battery completely discharge. (Discharing is only for older batteries with memory effects)
9. Hibernate not standby - Although placing a laptop in standby mode saves some power and you can instantly resume where you left off, it doesn’t save anywhere as much power as the hibernate function does. Hibernating a PC will actually save your PC’s state as it is, and completely shut itself down.
10. Keep operating temperature down - Your laptop operates more efficiently when it’s cooler. Clean out your air vents with a cloth or keyboard cleaner, or refer to some extra tips by LapTopMag.com.
11. Set up and optimize your power options - Go to ‘Power Options’ in your windows control panel and set it up so that power usage is optimized (Select the ‘max battery’ for maximum effect).
12. Don’t multitask - Do one thing at a time when you’re on battery. Rather than working on a spreadsheet, letting your email client run in the background and listening to your latest set of MP3’s, set your mind to one thing only. If you don’t you’ll only drain out your batteries before anything gets completed!
13. Go easy on the PC demands - The more you demand from your PC. Passive activities like email and word processing consume much less power than gaming or playing a DVD. If you’ve got a single battery charge - pick your priorities wisely.
14. Get yourself a more efficient laptop - Laptops are getting more and more efficient in nature to the point where some manufacturers are talking about all day long batteries. Picking up a newer more efficient laptop to replace an aging one is usually a quick fix.
15. Prevent the Memory Effect - If you’re using a very old laptop, you’ll want to prevent the ‘memory effect’ - Keep the battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries (which most laptops have) which do not suffer from the memory effect.
Bonus Tip #1: Turn off the autosave function. MS-Word’s and Excel’s autosave functions are great but because they keep saving regular intervals, they work your hard driver harder than it may have to. If you plan to do this, you may want to turn it back on as the battery runs low. While it saves battery life in the beginning, you will want to make sure your work is saved when your battery dies.
Bonus Tip #2: Lower the graphics use. You can do this by changing the screen resolution and shutting off fancy graphic drivers. Graphics cards (video cards) use as much or more power today as hard disks Bonus Tip #1 to give caution about turning off autosave, tip #8 to change information about discharging batteries - thanks to all who pointed it out. Added Bonus tip #2, Tip #1 to add in clause in regards to Mac OSX, Tip #1 about the spinning of hard drives - thanks to all who pointed it out.

Battery Charge Controller
solar panel 50 watts to controller charge with 12 volt battery?
How many hours can I charge it up to use a heater and refrigerator per hour?
The answer would depend largely on the ratings for the capacity of your battery, and the size of the loads you are trying to supply.
Most 12 volt car batteries will have a capacity rating of 70 amp/hours. That means that the battery is capable of delivering 1 amp for 70 hours. That would of course change, if you increase the amount of current being supplied to the load. For example, if your load draws 3.5 amps, your battery could only be expected to deliver 3.5 amps for about 20 hours - and so on. Keep in mind that if you are using a 120 volt inverter, 50 watts will only deliver 0.42 amps. The reverse is also true, for charging your battery. Your battery will only be capable of holding a charge, up to its rated limit. After that, it doesn't matter how long you continue to have your charger connected. You can always increase your capacity by connecting multiple batteries in parallel. Connecting them in parallel leaves the voltage the same but increases the amount of current by the number of batteries connected together.
