Radio shack battery charger for 4 batteries

It depends on the size and how old the batteries are and how many charge cycles they have on them. What type charger are you using ? New batteries should fully charge in about 4 hours on a standard charger and about 2 with a quick charger.

I think that your batteries may have expired due to old age and are refusing to hold a charge.

Ni cad batteries have a shelf life and once that time limit has expired, you need to replace the batteries with new ones which will begin counting down to their expire date and also go dead.
once ni cad batteries have expired and past their time limit
nothing can be done to revive them ,they are forevermore dead and must be replaced.

that is the reason why i buy 120 volt ac drills instead of battery powered drills which are always dead by the time i need to use them and wont hold a charge when i try to recharge them.

my cordless radio phone batteries go dead after 1 hour on the phone, when they were newer,i could talk for 4 hours and still have 1/4 charge left. soon they will only last 30 minutes and need a 12 hour recharge to come back to 4 bars.
so i expect to have to pay 4 new batteries by christmas.

One other option may be that your charger is not working properly and developing the required voltage.
that also happens but not as often as dead batteries that wont hold a charge.
if you have a radio shack nearby, even if its a 20 mile drive
they can test your batteries and also test your battery charger. just ask for a salesman that has a battery tester and a vom [volt,ohm,milli amp meter] also called a multi meter. The vom will test your charger and came also test your batteries, but most salesmen dont know enough about the vom to use it as a battery tester .

PS a battery tester is just a vom scaled down for battery testing only, made easy to use for dummies.

Radio Shack 230-0033 appears to be the same charger.

I have this charger (Nexxtech branded, model 2300033) and the specs all appear to line up. However, I don't have the manual.

Check the charger output, it should be about 4-5 volts higher than the battery pack voltage rating. If the charger voltage output checks ok then the battery pack is defective. Any Radio Shack store can test the charger for you.

the most simple way to run the radio from a charcher is to hook radio and charger to a battery
the charger will charge battery and battery will supply constant volts to run radio

go to radio shack or local dollar store and take batterie with you get the clerk to find you a new $3.00 - $10.00 batterie
take the batterie home place it in phone plug it in to phone replace cover over batterie place phone on charger after 4-5 hours on the charging cradle try to use it if it works
HARAYYYYYYYYYYY YOU DID IT

I have the same problem, and for now an external charger is the best solution. Also try resetting 4 times. I also got a new power supply, but problem persist. Good luck!!!

I don't know that I have your solution, but I do have a few troubleshooting tips.

Flashing typically means: your battery is possibly old, bad or is not making good contact. Clean your battery contacts with a pencil eraser to ensure they are making good contact with the charger. Also check your charger contact to see that they are free of debris. They can also be carefully cleaned with an eraser. (Do not use any type of solvents on either contacts.)

Second, check the date code on your battery. It is 3 or 4 digit number on the label. Batteries last approx. 18-24 months before starting to fail. Here is how to read the code: 835 would be 2008 the 35th week. If the battery is more than 2 years old, you should consider replacing it.

It is wise to have your radio turned off while on the charger. You can cause harm to the radio if you inadvertently press the PTT while the radio is on the charger. Plus, your radio will never fully charge if left on.

I would go to Radio Shack and have them explain the proper charging procedure as well as inquire about the red and green lights as not all chargers go green when fully charged-Normally red indicates a charging action and if a charger has no fully charged light, then a required charge time period is noted in the instructions. Batteries can be ruined by over charging!
