Is there an internal battery that should allow unit to be on when not in the cradle?

The original Sanik batteries have a negative side with about ten mm of metal showing on the side. Trim the plastic off your new batteries to match and the cradle charges again.

Is it the right cradle to connect. Sometimes the cradles look alike but actually are different. You can check the back and the bottom and see whether all the ports are the same between those cradles. Replace the battery and see if you suspect that is a battery issue. Some of those batteries are not really endurable.

yes there is an internal battery and it is the problem, the battery is "hardwired" into the GPS and it must go back to Garmin or an approved GPS repair station, to replace the battery takes special tools and the battery must be soldered back into the unit, any attempt to remove the batt without the spec tools results in a damaged and unusable GPS

Hello jcapsto. It could be that the backup or 'flash' battery isn't totally charged for one reason or another. This little internal battery keeps a minute current going to the units' flash memory that holds settings and other data and allows warm boots. I would recommend putting your CK30 in it's cradle with the main battery in overnight. Then trying removing the battery and it should spring right back to life. If not, then I would pin the issue on your backup battery and would implore you to contact Intermec or the vendor you purchased it from about replacement/repair. I hope this helps to at least isolate the problem. Good luck!

If the GPS's internal battery is allowed to discharge too far, it will not be possible to recharge with the card charger, until it is brought up to a certain level. Connect the nuvi to a computer with USB cable overnight. This will trickle charge the internal battery to a level that will allow the car charger / cradle to keep the GPS charged from that point on. Anytime the car charger fails to recharge the internal battery, the USB charge method will have to be performed first.

1. Plug the charger adapter into the charging port on the bottom of the HP iPAQ Pocket PC.
   Figure : Charging the battery
2. When the power indicator on the top of the HP iPAQ Pocket PC turns solid amber, the unit is fully charged and can be disconnected from the AC adapter (approximate time to fully charge a unit is four hours).

NOTE: The amber charge light blinks while the battery is recharging and turns solid (nonblinking) when the battery is fully charged.In the event of a low backup battery warning, charge the unit immediately before removing the main battery to avoid data loss. To view the amount of charge left in the backup battery, tap Start, Settings, the System tab, and Power.
Charging with the universal desktop cradle and AC adapter Use the universal desktop cradle to charge the HP iPAQ Pocket PC, or synchronize the HP iPAQ Pocket PC with a computer.
Follow these steps to charge the HP iPAQ Pocket PC using the universal desktop cradle:

1. Plug the AC adapter into an electrical outlet and connect the other end of the AC adapter to the AC connector on the universal desktop cradle.
2. Connect the serial or USB cradle cable into the appropriate port on the desktop PC.Figure : Connecting with the cradle
3. Slide the bottom of the HP iPAQ Pocket PC into the cradle and push firmly to seat it.

NOTE: The amber charge light blinks while the battery is recharging and turns solid (nonblinking) when the battery is fully charged.There are stabilizers located in the universal desktop cradle that assist in aligning the unit when there is no expansion pack attached. When placing the HP iPAQ Pocket PC with an expansion pack attached into the universal desktop cradle, the stabilizers will be pushed down by the expansion pack. To release the stabilizers for use without an expansion pack, press the button on the back of the cradle.
Charging with the optional USB Autosync cable Charge the HP iPAQ Pocket PC using the optional USB Autosync cable by connecting the Autosync cable to the HP Pocket PC and the personal computer. The HP Pocket PC will be charged using power from the personal computer.

Charging a low battery The HP iPAQ Pocket PC will not turn on if the battery has a low charge (less than 3.2 Volts). Fully charge the battery prior to using the HP Pocket PC.
If the charge on the battery goes below the 3.2 Volts as a result of not being connected to the universal desktop cradle or the AC adapter, no damage will occur to the battery. However, the HP iPAQ Pocket PC charge indicator light will not flash until the battery reaches the minimum charge of 3.2 Volts and a normal reset is performed.
Follow these steps to charge and reset the HP iPAQ Pocket PC:

1. Connect the HP iPAQ Pocket PC to an A/C power supply.
2. Charge the battery to the minimum level of 3.2 Volts (this will take 5 to 30 minutes depending on the current charge level).
3. Perform a normal reset by using the stylus to lightly press the Reset button on the bottom of the HP iPAQ Pocket PC.
4. Turn on the HP iPAQ Pocket PC.

Keep the HP iPAQ Pocket PC connected to the universal desktop cradle or AC adapter when it is not in use.

BATTERY INSTALLATION AND INFORMATION
Your wireless headphone unit requires two rechargeable AAA batteries.

Ouch, it is highly likely that you have overpowered the gps and it will need some internal repairs. If the item is less than 1 year old Garmin may fix it for you at no charge. If it is over 1 year old you can call them at 1-800-800-1020 .. It would probably be a good idea not to tell them that you may have caused the problem. We would not want you to void your warranty. Sorry for the bad news and please dont forget to rate me. Have a nice night.

here is a movie on how to replace Garmin's battery


YouTube - Replacing the Battery in Your Garmin

The sidekick 3 has an issue with thte charging port. If you have a friend with a sidekick 3 or sidekick ID, try one of their batteries. If your unit powers on, the charging port has gone bad.

the repair for a charginf port runs about 80-100 dollars. A cheaper work around is to get a charging cradle that has a spare battery charger slot. They run about 30 dollars on ebay and it will allow you to charge the bettery seperate from the phone.
