9/10's is about the trickle charging area. At 1.8 that is on the low side as it's more for 1800 mah packs so it's still going to charge slowly.

Default nimh battery

Yeah like 1.8 amps is just above a trickle charge for a 5000ma battery. Normal charge rate is 1C or for a 5000ma is 5 amps, fast charge is 2-3C or 10 to 12 amps so you are not going to hurt it with a 1.8 amp charger. 5 amp charger will take 10 to 15 min to charge it. Find an rc car guy near by they will have a charger laying around you can pick up for $20 -$35 that will charge 0-10 amps. Most cars now run LIPo batteries now so they have bought new chargers. Good luck!
