May read instructions and see if charger is compatible of charging the two types of batteries you are charging ,,,,I have 32 dewalt 18v dc9096 batteries and 1d dewalt 18v dc9099 battery

Firstly I would suggest that you check whether the problem is really with the charger or the Dc9099 Battery itself. All rechargeable batteries deteriorate over time, especially if they are left fully discharged for a long time or are frequently left on charge for extended periods.
If you have a spare battery try charging that.
You can test the charger itself with a digital multimeter (electrical test meter). 1) plug in your battery charger to mains supply and switch on. 2) Set the scale on the test meter to 200 volts DC Voltage (V--) 3) Insert the test meter probe wires in the sockets on the meter marked "Com" (black) and "V/Ohm (red) 4) Touch the other ends of the probes onto the metal contacts on the charger. It doesn't matter which way round you do it
If the voltage reads in the region 20-25V (will be either + or - depending on which way round you place the probes on the contacts )the charger is probably working okay.
If you have a battery charger that is for US Voltage (110)volts you can buy a 240V-110V step down converter quite cheaply here. http://cpc.farnell.com/_/mw2p-045/45w-230-110v-ac-ac-adaptor/dp/PW00942?crosssellid=PW00942&crosssell=true&in_merch=true&

Here is a link to a number of 220v chargers that will work for you. You can, of course, use the 110v charger with a down converter.

Hi mate,you need a step down/step up transformer,try e-bay they sell tons of them..50-100 AU$

You will need he correct charger, the 24V will destry a very expensive battery.

is this a north american model.all i can find is model DC727 & DC728 model. charger model 9116 & battery is DC9096 may work.charger volts 110v ac. if your buying the individual part like batt & chgr its more expensive than buying the whole kit is cheaper. hope i answer your question

all you needs is a step tranformer from 110v to 220v ac
