Default how long charging glow plug ignitor

Im just getting back into playing with my 1/8 scale nitros (Ofna and monster truck) but I just bought a lightly used Losi 8ight and it runs great. I start it with my old glow plug ignitor but I dont remember how long its supposed to charge since Ive been out of playing for years. Also can I leave it plugged in while at the track without damaging battery? I dont know the model anymore but it does have a green/red meter on top and it charges with a wall charger with a glow plug looking attachment. Thanks for the help

Wall chargers are trickle chargers so they can't damage the battery so you need to leave them plugged in overnight usually for a complete charge.
nothing to see here................................

The charger may have the output written on the label, I had one that only charged at 100mAh, if I'm right, a 1000mAh battery would take 10hrs at that charge rate.
10hrs x 100mAh = 100mAh.
I ended up cutting the lead off the wall charger, put a couple of wire fitting on & hooked it up to the battery lead on my LiFe/LiPo charger. Much faster charging.

With such chargers the formula is:

time = 1.4x capacity / current

If the current is 1/10th of the capacity or lower the battery will not be harmed.
The quality of an answer comes with the quality of the question.

I charge them on my charger at .4-.6 amps anything more than that and I feel they show a false peak.

Default charging

You can buy a charge lead so you can use a normal charger. If it's NiCad charge it at 4 amps and if it does false peak hit it again. sometimes they can be stubborn but they are designed to be charged at 3-4 amps.

NiMh like to be charged a little lower. I charge them at 3 amps. It may false peak but just hit it again to make sure. You will be surprised at how much better they work being charged correctly.

I charge both of mine at .8 amps on my Onyx NIMH/NICD charger.

It goes the full 90 minutes and then stops. I don't know if it ever gets fully charged or not. Seems to work good and lasts a couple weeks.
