Here are a few thoughts concerning charging a HNN9018 or HNN9044 battery in a SP50 radio:
1) Check the date code on your battery. Rechargeable batteries have a life expectancy of 2-3 years. Motorola brand batteries have a 3-digit number date code. The first number is the year of manufacture, and the next two numbers are the week of the year. Example: 352 would be 2013 (or 2003) the 52nd week.
2) Try another radio/battery in the charger and see if you have the same results.
3) Try charging the battery outside the radio. It will set front to back in the charger. The battery has an arrow on the bottom of it showing you which way to put it in the charger. If the battery charges in the charger without being in the radio, then your radio has a problem with the charging circuitry.
4) Clean your battery contacts with a pencil eraser, both inside the radio and outside, as well as on the battery itself. This radio's outside contacts are easily covered by film from hand oil and it will prevent the battery from getting a good charge.
5) Test your radio with another known good battery. If your radio is not working with the original battery and it appears to have not charged, it could be a radio problem, not a battery problem.
6) Try your radio in a different charger and see if you get the same result.
By this point in troubleshooting you should be able to determine if it is the battery, radio or charger.
This is the same charger as the Motorola XTN and CP100 radios. Your local Motorola dealer may be able to assist you, if you were to mention these models.
And seeing you are needing a charger, you might also check your rechargeable batteries age. The life expectancy of this style battery is 18-24 months. On the battery label you will find a 4 digit date code. The first two numbers are the year, the next two are the week of the year. Ex: 1107 would be 2011 the 7th week.
And as you are likely aware, this radio will also accommodate 4 AA batteries. (The AA batteries cannot be charged using the charger, only the Motorola rechargeable NiMH batteries are compatible with the charger.)
Your Motorola radios operate in the FRS/GMRS band, which is at 462 MHz. Police, fire, EMS services, etc. operate in the 150 or 800 MHz bands. Your radios cannot receive public service transmissions, and they cannot be modified to do so. Monitoring public service transmissions will require a scanner.

There are three methods of charging the HNN9044 battery used in an SP10 radio:
1) Use the HTN8232 10-hour wall charger. It plugs into a jack under the flap on the side of the radio (opposite side from the PTT button).
2) Use the drop-in style charger by setting the radio in the charger (this works if your radio has silver battery contact showing on the bottom.)
3) Use the drop-in charger to charge the battery alone. (The battery will set in the charge crossways to the way a radio would set.)
Lastly, if your battery will not charge by one of the above methods it might need replaced.
Here are some things to check:
1) Clean your battery contacts with a pencil eraser. (Both on the radio and charger)
2) Check the date code of the "new" batteries and see if they are less than 2 years old. (3-digit number usually with the first number being the year, the next two the week of the year. ex: 927 would be 2009 the 27th week)
3) The radios must be turned off when on the charger.
4) If using drop-in chargers try charging the battery alone in the charger.
5) Are all the chargers lights blinking? This can be a sign of a bad charger, shorted battery or wrong battery. You mentioned recently replacing them, are they the same chemistry as the previous batteries?
You did not mention the type of radio, so we cannot be more specific in our troubleshooting, but this should get you started. The beeping you are experiencing is most-likely the low battery beep. Your batteries are not getting charged. The above questions should help you narrow down the problem. If you need more assistance post another question and we'll try to help further.
The MT2000 can only be programmed by an authorized dealer. To have the police frequencies you would need permission of the police department, unless you were getting only the receive portion, which would make your radio be like a scanner.
Here are a few troubleshooting thoughts:
1) Check your charger contacts for film/debris. Use a pencil eraser to clean them. (This can be done on the charger and the battery.) If the charge light comes on and stays on consistently you know you have good contact.
2) Be certain your radio is shut off when on the charger.
3) New batteries sometimes need initialized. It will sometimes take 3 or more chargings to fully charge the battery. Check the date code of the new batteries to be certain what you obtained is truely new/fresh. Contact the vendor where you purchased the batteries and let them know of your difficulties in charging the new batteries.
