Yes it will work, I sell these chargers they come in different outputs.
Even the 300 mAh Output will charge it.
FYI The Lower the mAh output of the charger the longer the charging time. Its OK to slow charge, I actually prefer it, my
batteries last longer, even though there free LOL...
But you should read that manual, the unit should probably start off with a full 12 hour charge 3 to 4 times, (meaning charge it 1st time of 12 hours straight, then let it run down almost completely before recharging again for 12 hours, repeat this cycle), after that you can top it off with a hour a two charge. These method is the standard they don't usually tell you...
I know some smart ... is going to say different, but I could give a rat's ....
I will have to pick on of these up, if there any good I might sell them.
