You may be able to use a different base to charge the battery but chances are you may not be able to use the base with the phone since the base electronics are matched to those of the original phone and they will not match up.

As a general rule handheld radios will talk up to 2 miles line-of-sight. Anything you place between the two radios will reduce range. Talking from inside a building to outside, you can expect 1/4 to 1/2 mile. This being said, a radio can talk as far as it can see, so if you were on a mountain top, you could conceivably talk many miles into a valley below. Height and placement of your antenna determines range. Holding your antenna upright perpendicular to the earth will give you the best range.

Check your programming. It sounds like you have chosen a code number in one radio and the other radio has code turned off (zero).

Go to Settings on your phone turn on device as you start your Bluetooth on your phone. They should find each other and pair automatically but if they don't, turn off the device and then on again then immediately touch "scan" on your Bluetooth setting on your phone. If a new device shows up after scanning under "available devices" touch the new device name and it should pair. Good luck!

Yes, there is a non-replaceable, rechargeable lithium ion battery in the H15 bluetooth wireless headphones. See page 5 (page 6 of the PDF) of the manual; it's available here: https://motorola-global-en-uk.custhelp.com/ci/fattach/get/544996/1353537428/redirect/1/session/L2F2LzEvdGltZS8xNDk5MTE4MDMwL3NpZC9xSkJRV0htbg==/filename/H15_GB_EN_UG.pdf . I hope this helps. Cindy Wells

Rechargeable batteries fail after a maximum number of deep-cycles. Letting the battery drain completely before recharging, will shorten it's lifespan compared to keeping it topped up frequently. Replacement batteries can be found on Ebay and elsewhere.

Since the radios are from a yard sale, the batteries are likely bad. Transmit takes a lot of power, likely more than the batts can produce. Assume the batts are good, 1) same channel, as you said: 8. BUT, the same code? You need the channel and code to match. If you transmit on one, is there a blinking indicator or small screen indicator that changes? If so, your radios do work. You need to program them exactly the same.

The RMD has a set frequency list. Those are factory programmed and cannot be changed. Your baofeng can be reprogrammed to most frequencies. Critical! First, make certain both are in the same band: Uhf or Vhf. Make the list of frequencies you need both radios to use. If the RDM has it in the list, you are good to go! If it does not, and you must match the Bao, get a new radio. There are no mods or hacks for an RDM.

Could you be more specific? I have lots of desk chargers, are you asking for that or a mobile charger? Chargers are so cheap, I never made one.

battery, charger or charging port. No repair.
