HT-50 Ni-MH Batteries?

The Ni-Cad's for my two HT-50's are DEAD. I'd hate to replace them with Ni-Cad, since Ni-Cad's suck.

Anyone know of Ni-MH batteries for these radios?

NOT recomended, Sir.
The chargers will not support NiMtl Hydride battery chemistry.
I found the Motorola HT50/P100 batteries to be the best. Most ALL the other brands are not very good, you get what you pay for.
There were some serious issues with the rapid chargers for that series radios.
There is also a problem in the radio with low battery voltage causing severe stability problems which make the radio appear to have a bad battery when in fact the battery is ok.

I'm using the NTN4881A regular-rate desk chargers. Can these do Ni-MH?

Hi:

Well I hate to be the bad guy, but really
I would try and just bite the bullet on the
HT50/P100 Series Batteries.

If you do not want to get raped by ~//~ consider a after market battery.

Also, the HT50's are known for poor on/off
switch contacts, so even if you get a New Battery and the power is still low, the Volume Control Switch should be replaced.

I can get them for you @ wholesale plus a few
bucks in shipping if you wish, but even then
I think the wholesale cost of the battery for
a HT50 is around 50.00

Funny a battery than is only ounces, costs
more than some Die-Hard Batteries that are
50-60 pounds.

Anyhow, if interested, email me direct
[email protected]

I'm quite sure the batteries are a fault in my case. The HT-50 batteries won't give any reading on my voltmeter, even after being "charged" overnight. (And, yes, I checked other radio batteries to be sure the voltmeter works.)

I'm in the process of ripping out the old Ni-Cad cells of one of the dead packs. I'll wire up 8 x 1500 mAH AA Ni-MH's in series to provide the rated 10 Volts. AA cells fit great into the battery casing!

If it explodes, I'll let you know, so you can laugh at me.

Be safe and always wear safty glasses when working on batteries and cells. If it explodes, then you will be in no condition to let us know.

The slow charger should be ok for the Ni-MH battery cells. DO NOT use the rapid charger for other than Motorola NiCad batteries.
Be sure to put some "glue" to hold the cells from sliding around and shorting in the battery housing. We have had a lot of the aftermarket batterys short out, melting right thru the battery into the radio.
