I have two T5700 Talkabouts that I was given by a friend. He could not find the charger, only the radios. So I purchased a replacement Motorola charger online.
Unfortunately, when I put the radios in the stand they do not charge. No lights, not nothing. However when I got the radios originally and even now, they batteries still have some charge in them. I'm guessing it's been 2 years since they were charged, but they still work. So I'm thinging the batteries are not the problem.
I tested the charger and it is outputting 16v DC to the charging pins and the pins seem to pop into the charging slots when I put them in the charger. Just nothing happens.
Any suggestion what I need to try next? I hate to just throw them away.

There is nothing wrong with your battery or your radio. you bought it a walmart at the lowest price available. this means you get what you pay for i.e. no frills the indicator flashing means it is connected to a power source and is charging / Maintaining the battery. it will only come on again when the battery is below 1/8th of the battery life and flash to let you know it needs to be charged again. there is no battery level indicator. these will work just fine but dont expect the 1-16 mile range they advertize unless you have full charge alkaline batteries and a direct line of sight to the one you are talking to.
Parts for the small size TalkAbout line of radios were never offered to dealers, other than batteries, chargers and accessories. Your best option is to purchase a used radio from ebay to scalp for parts, or possibly by contacting a vendor such as www.wirelesspro.com, who deals in lots of the smaller TalkAbout radios. They may have some which have been scrapped for parts.
The larger TalkAbout line of radios, such as the TalkAbout Distance and Distance DPS are repairable radios, and many parts for them are still available.
No, the charger is only usable to charge the rechargeable NiMH or Li-Ion battery which comes with the radio. Attempting to charge Alkaline rechargeable batteries with this charger could cause the to expode.
If your charger is not charging the batteries which came with the units, it could be you do not have the charger cord end plugged in all the way, or the batteries dropped below the initial charge level by setting on a store shelf too long. Most TalkAbouts come with a cradle style charger to hold the radio, and a possible plug to plug into the charge hole. Check all connections, and clean any battery/charger contacts with a pencil eraser. To re-initialize the batteries you would need to attempt 3-5 charge cycles by charging for 8-10 hours, then letting the battery rest for 8-10 hours, repeating 3-5 times as needed. If this does not bring the battery back to life, you need to replace the batteries.
If you are referring to a flashing yellow light on the charging base, this is an error code. Either the 1) battery is bad, 2) not making good contact in the charger, or 3) very very low on charge. The solution for this set of problems is as follows: 1) have the company you purchased them from replace them, 2) clean your contacts with a pencil eraser, 3) leave the battery on the charger with the yellow light flashing for an hour or two. If the battery is just very low on a charge, it will come back to life and the light will change to be constant. If the battery is bad or shorted out, the light will continue to flash and you will need to get with the vendor you purchased the batteries from.
Other things which come to mind are compatibility issues such as you are using a different battery chemistry than you had before. NiCd batteries can charge on either of the two chargers available for the P110 (slow rate or fast rate). However, NiMH and Li-Ion batteries require a fast rate charger.
If you are referring to a yellow blinking light on the radio while it is in the charger. You need to shut your radio off. Radios should always be turned off when charging. If the radio is left on you will never have a full charge. Also, if you inadvertently press the PTT while the radio is turned on, while on a charger, you can cause damage to the radio.
FYI: There is no light to show "out of range" on the radio, unless you are possibly using a trunking or repeater system. A blinking light on your radio indicates the radio is turned on and/or there is traffic on your frequency. Your charger base light can be red, yellow or green. This indicates the charge cycle status. Flashing most always means some type of error.
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.
I'm assuming you're using the NiCd batteries. NiCd batteries do not last forever and need to be replaced when they show a resistance to beign charged. To optimize the life of these batteries you need to let them fully discharge before attempting to charge them. This is impractical most of the time.
You have two choices:
1. Purchase a NiMH charger and AA batteries and use that INSTEAD of the CHARGER STAND and NiCd batteries. This type of battery can be recharged without the problems discussed earlier and will last longer... or
2. Purchase another NiCd battery pack.
Normally in a Motorola T5700, to set a specific channel to monitor (and reply to) called your working channel, you press the Menu (center) button and the current channel shown in the display will flash. Press either the + or - buttons to change to your desired channel number which should be identical to both radios. Press the PTT button to save.
Likewise, both radios must have identical Interference Eliminator Code. To set code, press Menu till the code display blinks. Press + or - to select code. Press the PTT to save. To disable the code, select 0.
Hope that this be of help/idea. Pls post back how things turned up or should you need additional information.
