RC battery Help

Attempting to recommission my sons GrassHopper - ordered two replacement battery's @2100ma.
Plugged into car and had a blast for 20 mins or so - however now when i've plugged them into the charger I was given (Vector NX85) nothing seems to happen.
The power indicator illuminates,
The fast charging indicator stay's unlit
The charged / trickle stay's unlit
I've tried using 1.0A and 2.0A selections ?
Any ideas ?

How did you charge them before use? If both are not charing, then it is either an issue with the charger or user error most likely.Plugged into car and had a blast for 20 mins or so - however now when i've plugged them into the charger I was given (Vector NX85) nothing seems to happen.

Sorry forum wasn't letting me reply till now ...
Fully agree it's user error, but i just dont see where.
The batteries are NIMH stick type. The charger has a tamiya type connector, as do the batteries - so Im' not sure it's possible to connect them up incorrectly.
This is the charger ,,,
ignore the connectors being unplugged etc, i'd ran out of hands

lol, not saying it was user error. But it would be unlikely that 2 batteries would fail at the same time. Therefore it leaves only 2 options:
1. The charger has gone faulty or has a problem (blown fuse etc.)
2. The charger is fine and you did something wrong
If you don't think it was number 2, then it must be number 1.
NiMh can be a pain to charge though sometimes. They can false peak and don't like to be too flat either (unlike NiCd).
Getting yourself a modern smart charger might be an option and maybe a multi meter so you can check the batteries.
I use one of these:

However there are loads of options these days. But you don't need to spend loads on a charger if you don't want too.
And a multimeter like this is handy to have:
