If you pull of the back cover you will find two small fuses near power supply, one of these allows power from battery pack, check with voltmeter for open circuit, I take it that it is not just one battery it does this with.

    I was electrician on construction site and we had same issue twice, the fuse blew twice once when we inserted a battery that a backhoe had reshaped and the other time was caused by chargeing packs on gen set that ran out of fuel.

    If you only have one battery it will be that battery is stuffed, if on the other hand it does it with at least two known working battery and you are sure it is not one of the two 2AG fuses then, check battery contacts on radio, if it aint that then it will be the only board in it has a problem(or lead to it), if you know how to use a multi meter then check from where the battery connects, after contacts, to board, threw components ie trace it to where the power stops and there is your problem "where it stops". without plug into mains, but with battery in, wont kill you, is only 13.6v i think.

    Battery, fuse, connector terminals, cable. board, are your possibilitys in order of likelyness.

My dewalt dw911 radio was working great. I put it away at the end of the day and in the morning the aux was not working properly. It only plays through the left speaker and half the channel is missing...

Is the Aux jack plug or USB or other? its probably a poor connection, slide the plug/or USB in & out untill it works. the sliding in & out will cause the contacts to rub against each other and usually removes enough oxide to allow a connection again.

I have a Dewalt radio (Dw911) that will only play off the battery, not the power cord. I have checked both fuses and found both to be good. It sounds as if this is a common issue but I have found no...

Mine had the same problem .Try swapping the fuses. Although the fuse looked good mine was bad. Easy fix I hope. Going to auto parts store for new ones.

My dewalt dw911 radio/charger works on either mains or battery but wont charge a battery and blows an internal fuse when both are used together

More than likely your internal charger is faulty. Inside your inernal charger unit check the 2 anmp fuse which is white in colour.

Sorry but does the dw911 xe type 1 radio charge the battery

Yes, the DeWalt radio will recharge the batteries, from the 12 Volt to 18 Volt versions. However, even with the radio plugged into an AC outlet, you have to either have the radio turned on, or have the unit in the AUX setting, in order for the batteries to get charged.

It typicaly takes about an hour +/- to fully charge a discharged battery. I normally don't put batteries directly into a charger right after they become discharged from being used in a tool, since they are still warm from use and charging them will generate more heat in the recharging

Heat is the enemy of rechargeable batteries, so to get the longest working life out of your batteries, I'd let them cool down first, before recharging them, unless you absolutely need to use them right away, then go ahead and recharge them. If you can delay recharging them until they've cooled down, you'll get a more fuller recharge out of them.

Hope you find this Very Helpful and best regards!

Have you changed the AA Batteries, this is often the fault, when they are flat they lock the radio out. HHM Dewalt Service
