Most automotive electronics work on a 12 Volt DC system. You must be using adapter capable of providing about 12 to 14 volts because car batteries provide 12 volts; but car alternators put out 13.8 volts. Do not attempt to connect to an adapter that put out AC voltage!
You just need to set black & decker charger to 12V . Don't make mistake while connecting + / - leads. + lead usually come with Red color cable. You can use the AVO tester to justify the lead cable. The charging time is normally about 10 -12 hours (or just just check the status on your charger display). If your charger does not has trickle charge facility, you have to disconnect your charger after 12 hours continuous use.
Also, you can find the guidance about your charger here :
Hi, leaving the unit in the cradle exposed to the sun during hot days has been known to fry the battery causing loss of battery capacity. perhaps this could be your problem. I replaced the battery in my last GPS 4 times because of this before I analysed the problem. This will most likely be outlined in your user manual too. You might also compare the output capabilities between your blackberry and tomtom charger - it is entirely possible that you are starving the unit of a decent charge if the blackberry charger is not to the same current capacity as the tomtom charger.
do you have a volt meter toi check the charger voltage? if so then read the voltage out of the charger, it should be 1 or 2 volts higher than the listing 12v would be 13 or 14 volts. if it's working you probally do have a bad battery. if the charger is out then you have a bad charger.
I hooked a 12 volt car battery charger to the battery for about two min. Then I put it in it's own charger,the yellow & green lights came on for about 5 sec. then the red light came on . About 30 min. later the green light came on and the battery is fine.
I have the same tomtom and it has the same problem. Sorry to say it is the battery. You cant change it it has to go to Tom Tom. I just bought a new one. Hope this helps.
Hi John.
No idea why your post is under monitor problems ???
I figured you need an adapter mod for a monitor !! SO don't kill my
ratings since this is not my area of expertise, but I can try to give
you some input anyway, not so much a solution !!.
I would NOT recommend altering a 12 volt adapter for charging a battery
especially if it is a standard ac adapter.. You may get it to give you
13.8, but your amps may be wrong.
Battery charger depends on type of battery also. Don't know if you are using NIMH or Nicad or acid based ?
The differnt style batteries use different type chargers. Wrong charger will burn up a battery or blow it up !!
If the battery is a 13.8 then normaly the charger would be putting out
2+- volts more than the battery rating. If you battery is 12 then a
13.8-14 would do the trick. (12 volt car batteries for instance take a
14+ volt source to charge them)
I would recommend looking here

They have all those goodies and may give you an idea. for what I think you are doing.
