CP200 Battery Problem

[CDCourier]

I purchased some aftermarket batteries for our Motorola CP200 handhelds. After charging them fully, I changed the old batteries and put the new ones on. The radios turn on and receive fine. However, when you push the transmit button to talk, it keeps transmitting even though I've taken my finger off the transmit button.

The battery brand name is Arrow Max 7.5V 1800mAH

Does anybody have any idea what is causing this?

If I put the old batteries back on, they work fine.

Make sure that you have the correct antenna on your CP200, as TX RF can get into the radio maybe thru the battery.

Also try it into a good known test, dummy load.

cheap batteries loading down and the low voltage is driving the radio stupid. i've seen it more than once, and soemtimes it will brick the radio. i'm not saying to buy the high dollar /\/\ batteries, but at least get aftermarkets from a known and reputable company such as Interstate or even Multiplier(though these are not all that great for SOME radios).

Arrowmax... You didn't get those on fleabay did you? Ideally you want to stick with /\/\oto originals; if you must go aftermarket, I've had good luck with PowerProducts and W&W (though according to some people that stands for Weak and Wobbly)...

Think this boils down to you purchase of an $18 battery. The CP200 battery is notoriously finicky, even OEM Motorola ones rarely last more then two years. Not sure what the deal or what causes it.

Had similar issues with other non-OEM batteries for the CP200.Empire Scientific,PowerGain and Honeywell all had memory or voltage issues. Changed to Power Products and things have been fine since.
And the Motorola MAG ONE econo batteries with clear housing also had issues.
