Old light... New battery?

I have an old Cygolight that is powered by 6 "D-cell" batteries........ I know the new Cygo light plugs into my light but is the watt. or amps to much? I am curious as it would be nice to have a back-up battery..etc!!

TIA
Aaron

Depends on the voltage. Check with Cygo. Your system, if you are correct about the number of cells, is 7.2V for NiCd or NiMH.

6 D cells is 9V. So, any 9V battery pack should work just fine. A lower voltage battery pack won't hurt the light, but it might not be as bright.

6 D cells in alkaline are 9V. Not in Nickel chemistry. 6 cells @ 1.2V per cell is 7.2V.

Don't worry, I thought the same thing until I realized that there aren't any 9V systems that I could think of out there.

That's true, but was the original light designed for alkaline or rechargeables? In any case, the light will be brighter at 9V and still be operating at a safe voltage. Batteryspace.com has both 8.4V and 9.6V nimh packs, either of these would work fine (as would a 7.2V pack)

An 8.4V pack might work but the 9.6V would probably be too much. A 7.2V is pushing a 6V bulb 10%, I'm not sure you can push them 30% and still have any useful life for the battery.

Most of the Cygo systems I've ever seen are rechargeable. All battery has a very nice 4500 mAh RC car battery for around $30.

I am not certain what you are asking? Do you have a current battery and plug? Does your current light have a jack? Regardless, I have two cygolites. One charger says 7.2 and the other says 6 volt. They both have the same plugs and both power "6 volt" systems.
