6V versus 4.8V - does the T2 care?

[Spiff]

Am wondering if the T2 will be finicky and require four 1.5V alkaline cells, which I assume are in series, for a 6 volt total, or if four NiMH rechargeables at 4.8V (1.2V x 4) will suffice. Will the lower voltage affect performance?

I don't suppose there is room internally to replace the 4-cell battery pack with a 6-cell version? One could jumper the sixth slot with a wire and run five NiMH's yeilding: 5 x 1.2 = 6V

I havent used rechargeables in mine. I have researched the different voltages between alk. and rechargeables. What i have learned is that the reson for the rechargeables having a lower voltage is That They are more stable with less fluxuation in voltage readings. Where as the alkaline voltage fluxuates up and down alot and is more unstable, and to compensate for these fluxuations the voltage is higher. The t2 should do fine with rechargeables....just get batteries with a higher rating.

It states in the manual rechargeables may be used. I put a set of NimH that were partially discharged in as my first set and ran it for several hours with no problems.

There is probably a regulator in the circuit. The circuit may actually operate on 3v, and the higher battery voltage is reduced to that level. Thus, the typical AA can be at a fairly low voltage and still work.

The battery companrt is split in two sets of two AA's. Adding cells would be a serious mod. You'd be better off adding a single holder outboard and leave the machine unmolested inside.

I doubt it would matter much anyway. Maybe a bit longer battery life.

Rechargeables produce 1.2v versus alkaline's 1.5. For 4 cells in series, if that's how it is wired, yes you do lose 1.2v when using rechargeables.

My guess is it's regulated below tht figure, so any amount over is just regulated down anyway, thus no difference in how it would operate.

Regargeables can dump more current faster than an alkaline, in high-power use, this does result is less voltage drop.

I doubt the T2 is a high-current device or it would only last a couple three hours on a set.

So, not an issue, in my mind, which type you use.

You'll get fewer hours with rechargeables, this is why a higher capacity cell is better, it'll last longer between charges. It won't
"amp up" the detector in any way over alkalines.

It's already almost too hot, why worry about hopping it up even more?

Thanks for the reply, Ed (and others). That's all I needed to hear: "the manual says rechargeables are ok". Think I'll plan on using some 2500mah Energizers. Cabelas is about to hear from me!
