While I try to use factory Motorola batteries any time I can, I have purchased many used Jedi radios, & they came with various "generic" batteries which all worked well. The exception was W&W batteries. They are absolute JUNK. I bought 2 new STX batteries from them. While they would rx for 27 hours, if I tried to tx, I leard the "low battery chirp" right out of the charger. I requested a warranty exchange, & they sent me 2 more. Same JUNK. Right out of the charger, the batteries were weak on tx, & the "low battery cricket" was still there. Motorola batteries did not have this problem. I gave up on them, & just used them for rx, which they did well. If they were the last battery vendor, I would sell that radio, & get something else where I could buy a battery from someone else. On a 1-10 scale, W&W gets a -12.
