NiMh Battery Charge Timeout

[SXFoxstar]

I am pretty sure this is me and not the battery but I am charging a 5100mah NiMh battery with the SkyRc T200. 
 

I keep getting timeouts on this battery. My 3000 and 1800mah batteries charge fine in respective amperage.

 

I am using NiMh auto charge and using a cautious 4.8a charge setting. Nearly every, but not all charges I have to charge a second time to get a proper charge due to it timing out. Is it just I need to up the amperage (I thought you could go as low as you wanted it just takes longer) or is it suggesting something “off” with the battery?

 

Thanks

You could bump it up to 5a but I'd be turning off the time limit if you can

@Fred barlow Now I feel a silly boy ☺️ I’d assumed the “auto” charge was all singing all dancing. Didn’t realise it was as simple as increasing the timeout limit, thanks.
