Load the plastic carrier with the NiMH or NiCd batteries. This will give you 9.6v 9.6v is fine for your router. I you feel that you must drop the .6v, put a silicon diode in series with the pack. That will give you 8.9v The router has an internal voltage regulator. It is quite normal to feed the router with 9V but the router actually uses 5V. You cannot "just use a 9v battery" if you need 800ma. The battery pack has no problem recharging with batteries in series (I wonder what he was smoking at the time). Here is what I did.... All of my network devices are now 5volt. I built a 5A 5V power supply, and all of my hubs, routers, wifi hardware, are now powered by the 5v supply. No more wall warts! and when the power fails, the big UPS powers the 5V supply.... the 5v supply is actually just a regulator off the batteries inthe UPS.<a href="http://www.popwebshop.com/health/"> ►BobB◄</a> just buy an 8 cell battery pack.

Boy it is impossible because series battery cannot be charged, but i can give you 2 alternate ideas . when you connect the 8 batt erys in series the Voltage is increased that is 1.2 x 8 but the current is same . when the batterys are charged the charger circuit takes the battery as if a 9V 2000 ma battery is connected. so all the battery want get charged. so how can u use it. . i think there is no 9v rechargeable battery iam not sure, but u can use a 12V1.5A battery just simply add a 3 volt bulb inbetween. . the simple way is just use computer UPS which will give you a good back ( microtec double backup ) . .

Personally, I'f get a 12V gel cell and charger, and run the router/modem off of that, if not an actual UPS.<a href="http://www.felinehealthguide.com/feline-breed.htm"> classicsat</a> Just hook them in series.

You would have to buy some sort of low-power relay to switch power to the batteries when the power is out. The backup wouldn't last very long, but it does have a high enough amperage.<a href="http://www.besthomeorganizers.com/700"> James</a> connect batteries in series, you can go to electronic hobby stores and buy battery packs for this.

Actually you may need more than one, because a single battery, may not provide enough power. Back to the original question. 6 1.5V batteries in series will give you 9 V, but I doubt you will have enough current to power a router.<a href="http://www.prohomeschool.com/free-homeschool-worksheets.htm"> TV guy</a> And why don’t you just buy a 9V battery?
