• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

NTN7143C battery charging

Not open for further replies.


Apr 20, 2012

I've got a GP900 that uses a NTN7143C battery and a NTN1172A charger.

The question I wanted to ask is related to something I noticed on my other radios. I also have a pair of P210 with NTN5521B batteries and NTN5380B charger. There is a notice on the P210 battery that says : "For propper performance on first charge or after prolonged storage - 14 hours minimum charge time. Subsequent charges to be 1 or 14 hours depending on type of charger." 14 hours is the charging time on the "slow" charger for that type of batteries.

So, my GP900 was stored for a "prolonged" time. I read that the "slow" charging of NTN7143C batteries takes 16 hours. Does anyone know if there's a notice or an instruction on new NTN7143C batteries that says to charge them for 16 hours regardless of the charger type after prolonged storage or if it is advisable? Thanks.
