Battery not charging


If a battery seems unable to hold its charge, it may have a defective cell or an electrical short that makes normal operation impossible. Check the electrical system. A faulty car electrical system may also cause premature power drainage. Battery terminals may grow dirty or develop corrosion, interfering with proper performance and causing the battery to deliver more power than the situation actually requires.

Sony batteries BP-HP550


Even though you can use regular AAA batteries (that you would have to replace often), there is a huge convenience factor with using the charging cradle that comes with the Sony headset. A solution I found was that I ordered some 550 mAh AAA batteries through Ebay (they came from England and cost me $8 total for four batteries). To make the charging cradle work with the new batteries in the Sony headset you MUST use the bottom part of the plastic battery holder piece (all you need to do is peel off the BP-HP550-11 label and the bottom half of the plastic battery holder piece slips off of the Sony batteries). Then just slip in the new AAA batteries into the plastic battery holder bottom and then insert into the headset. The reason why you must use the bottom of the battery holder plastic piece is because the plastic piece pushes on a little switch. This switch activates the charging mechanism to enable the cradle charger to charge the batteries.

NOTE: I am not an electronics expert so I do not know if there would be any problem using other rechargeable AAA batteries (with higher mAh ratings). So I decided to be safe than sorry and ordered the 550 mAh batteries through Ebay.

The amber light on the power supply on my HP 550 laptop is flashing 8 times when i press the power button.it does not start ....


This is taken from page 11 of the user's manual (http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c01627018/c01627018.pdf)

Blinking amber: A battery that is the only available
power source has reached a low battery level. When
the battery reaches a critical battery level, the battery
light begins blinking rapidly.

In other words, attach the charger to the laptop and let charge for at least 1 hr before trying to restart your computer.

My calculator drains a set of four batteries with every use. Why?


I am not sure what every use means: duration, programs running etc. But that drainage is properly excessive. TI estimates that with 2 hours a day of usage, the batteries should last a school semester.

Possible causes of rapid drainage.
The most common causes of rapid battery drain are mismatched batteries
  1. Batteries of different brands
  2. Batteries of different types (alkaline (1.5V + rechargeable NiMH 1.2V)
  3. Batteries of different charge levels (new batteries with old ones)
  4. Negative charge build up
Another cause of rapid battery drain is the use of third-party programs: Certain of them keep large amounts of data in memory. Some of them are tweaked to bypass the TI power management scheme and disable the TI APD (automatic Power Down ) after 5 minutes of inactivity.

Possible remedies
  1. Remove all batteries (main batteries and backup battery)
  2. Leave them out of calculator for about 15 minutes. (Beware that this will clear the contents of the memory and that data will be lost along with all applications installed). However Applications cam always be reinstalled once calculator returns to its normal state.
  3. The possible benefit of the removal of all batteries is to make the negative charge build up disappear.
If that fails
If the foregoing steps fail to restore the calculator to its normal behavior, you may have to contact TI Customer Assistance by filling out and submitting a customer assistance form.

Battery drainage


20 to 30 shots on "fresh" batteries! Do you use the flash on all shots. That really drains them. I would try to set the camera to "factory default settings" in case you changed something that is causing a drain. I hope you just bought some bad batteries.

The best thing I EVER bought for my Olympus was the Re-chargeable Lithium Ion batteries. The worst thing I did was buy an off brand. That was a waste. I ended up getting the more expensive brand Olympus recommended and all was GREAT again!! 1,000's of pictures later and they still work great.
Good Luck

2006 Corolla LS battery continual drainage


difficult to accurately *****, you need to get the charging checked, even though you have a new alternater the problem could be as simple as the charging light not working, which causes the alternater to initiate. or you may have an electrical component staying on draining the battery.
