Has anyone had any problems with leaving their Pro-95 (or other RadioShack scanner with the yellow rechargeable battery pack) plugged in and charging all the time?

Yeah, it has rechargeable batteries.

yeah..
doesn't matter which pack I use..
if I leave it on and plugged in with batteries in the unit, later on when I unplug it I can not get it to turn back on with the battery pack only.
this has happened twice.....
I just take the batteries out when I power it with an AC adapter

And you leave yours plugged in all the time as was the original post?
It's NOT good to leave any rechargable on charge all the time. As others have posted, they will leak, explode, or short and create a lot more heat than you want in your scanner.

You should allow the batteries to drain completely before charging. Topping off of batteries shortens the life span of the battery.
yea i had recharglbes in the yellow tray and mine exploded and melted the actual componets of the pro 82 luckily the manager of the rat shack was cool so he let me return it even though it was my fault and that's when i got my favorite scanner, the pro 95!! i have yet to make the same mistake, whenever i'm not carrying the scanner i have the battery pack out and just have it powered through the wal wat, i charge all my rechargables in a big recharger put out by rayovac and aint had a problem since

Isn't that only with the NiCads? I understood the NiMHs don't have this problem. But I could be wrong.JMedley_1 said:

With Nicds you have to let the batteries drain all the way. You don't have to do this with MiMH batteries but if you do the baterries last longer. Also the higher the capacity of the battery the lower the lifespan, 500 cycles compared to ~1000.

Nope - it applies to BOTH. NiMHs are more resistant to memory effect (the effect that shortens the bettery life), but NiMHs are not immune to it.
Two sure ways to destroy any type rechargable cell:
1. Leave it on charge all the time
2. Repeatedly use it for a little bit then put it on charge.

Battery Charging Tips
General Tips
Make sure to read the manual for instructions when charging a battery internally. Not all chargers are equipped to charge all types of batteries.
For the charge times for different types of batteries, you should check your charger's owner's manual. The time required varies according to the type of charger and battery.
To test the charging rate of a charger, a multimeter must be put in series with the battery and charger to accurately measure the rate. Follow the instructions for testing current with the multimeter you are using.
Be careful not to overcharge batteries, and especially when charging Ni-Cd and NiMH. These batteries can overheat and burst.
When Charging Ni-Cd Batteries
Be particularly careful not to overcharge Ni-Cd batteries. These batteries can overheat and burst.
Be sure and discharge Ni-Cd batteries completely, at least once per month, to avoid creating memory and reducing battery life.
When Charging High-capacity Ni-Cd Batteries
Be particularly careful not to overcharge Ni-Cd batteries. These batteries can overheat and burst.
You should charge Ni-Cd high-capacity batteries with a charger designed for batteries with a higher capacity (mAh).
You should not use a charger that has an automatic timer cut-off, as it will cut off before the battery is fully charged. If the charger has an auto-off feature which will stop charging when the battery is fully charged and it does not have a discharging circuit, you can get a full charge by running a second charge cycle.
If the charger does not have auto-off, you run the risk of overcharging the batteries. If it has a discharging circuit, it will discharge the battery rather than completing the charge cycle.
Be sure and discharge Ni-Cd batteries completely, at least once per month, to avoid creating memory and reducing battery life.
When Charging NiMH Batteries
Be particularly careful not to overcharge NiMH batteries. These batteries can overheat and burst.
When Charging Lead-acid Batteries
Most devices which use lead-acid batteries are designed to recharge the battery; we do not carry any additional lead-acid battery chargers.
Never discharge Lead-Acid batteries completely. If they are fully discharged, they will be dead and no longer able to be recharged.
When Charging Rechargeable Alkaline Batteries
Never discharge rechargeable alkaline batteries completely. If they are fully discharged, they will be dead and no longer able to be recharged
