XTS2500 Battery Question

[MDFR_TCOMM]

As some of you know, the XTS2500 brings a battery that charges in the XTS5000 series chargers. But you can put an HT1250 (Harris) battery and the radio works fine. I know about the IS and rugged ratings will not be valid BUT nevertheless the 1250 battery works on this radio...

Now, here's were some issues arise, the 2500 with 1250 WILL NOT charge on the 5000 due to its different width, thus it fits on the 1250 charger - Follow me so far?

If you insert the 1250 in the 1250 charger works as it was designed to, BUT if you keep the radio attached it does not. I have configure it in such a way that it does charge by elimating the temperature sensing pin on the battery.

From a stand point of a user that does not want to spend a lot of money on batteries and I have a bunch of 1250 batteries, how critical is this temperature pin? Can I be without it? Again remember this is for my own personal use and will not be utilized on any entity.

Thanks...

I would be very concerned about disabling that temp sense pin. Without it, the battery could get too hot due to overcharging and cause damage to the radio, the charger or both. Not to mention the risk of fire...

Simple solution: keep a spare charged battery around. When the in-use battery dies, pop it on the 1250 charger and start using the second battery.

I agree with Tom, you could damage both, however, if you were to closely monitor the temp yourself, and remove if it seemed to get too hot, or even rig up a cooling fan of sorts? Good Luck.

I would just not charge the battery while attached. Actually, I would just get a pair of Impres batteries and an Impres charger since they are even cheaper than the XTS/saber.jedi line.

Years ago I had an HT750 with this problem. What color is the gasket around the battery contacts on the radio? If it's black or orange, send it in and have them perform the "containment kit" modification. It will come back with a blue gasket around the battery and should then charge...

I think he's saying that the 1250 battery will not charge in a 1250 charger if attached to a 2500 radio.

If so, that's normal.

Thank you for your responses and yes it is a 1250 battery in a 1250 charger but the radio is a 2500. The pin that I am disabling is the one on the radio side not the bottom ones that bond onto the charger. If I put the battery by itself, it gives a full charged cycle, but when the battery is attached to the radio (in the OFF position, like it should be) the charging light blinks rapid red after a few seconds in the charger.

With my modification of the disabled pin, I have not placed the unit for a full cycle, that is why I am posting the question on this forum. I am not ommiting the base temperature contact going into the battery, if I do this then the cell has no way on knowing when to trickle.

To be more specific, if I "tape-off" the pin that touches the radio terminals, would it affect the actual battery charging cycle? Without affecting the radio itself?

Thank you all again,
