Where can I purchase Rechargeable Battery Pack BATT 2P 7.4V 3600mAh Li ion Model number CHRR-2

Chances are there won't be a direct part replacement for it. But if you can examine the Li-ion battery that's in it, it will have a model number and rating on it that you can use as a cross reference. There are a ton of rechargeable battery packs on ebay and you should be able to find a close match. It may require the battery connection leads to be swapped and soldered into place from your old pack to the new replacement battery pack.

Lots of places:

I did not see what camera model you have, so the selection here covers a few.

you can find in radio shack or computer stores or electronic suppliers parts.

God bless you

I have one of these but don't know what is is used with ? Can you help ?

Power Source Li-ion Rechargeable Battery (LI-42B) Are you using the above battery?
Check the voltage to make sure it has enough as printed on the charger or the battery.
Alkaline rechargeables, or NiMH rechargeables, or other types of batteries don't have enough voltage or amperage as compared to Li-ion.

i need a charger for my radiob rm75sfcc model pma3g2000 and also a battery charger from the radio to the charger

Oh my, not good. Well, you do need a battery pack. Contact the MFR for replacement pack via customer support, or check the voltage on the side, if using 9V, get a battery holder that uses 8 batteries[2 Xtra cells are used to disable the shutting off at too high a voltage due to the missing battery pack]go to battery space.com, and go to wires/connectors, and get the laptop connectors to make an external battery pack. Therte is a battery pack charger/I recommend accupower evolution. You have to google and go to other sites to get the rechargeable batteries and battery holder. You can get by with alkaline, but they would go rather fast due to the large screen size. You need that good brand name so they can be evenly charged due to the batteries being able to be run down further. You wont be wasting much voltage with alkaline due to the lower cutoff voltage, but 1st try contacting the mfr or googling to get that battery pack!!!I Hint: if using battery pack and you still want to add more battery life, drop the batteries to 6 on a 9V circuit. with original battery pack on, a 9V circuit would use 6 D cells on an external pack, 8 for a 12 volt.

Contact BatteryRefill.com, they will rebuild your battery at a fair cost, compared to buying a new one.

I wrote to Walmart.com. The corporate office. They contacted my local store and the store replaced my machine with a brand new magnavox even though my machine was 1 year old, Try it. They told us that customer satisfaction was guaranteed. They also told us that the company was out of business.
