M41 Walker Bulldog battery charge

Hello,
I just got a M41A3 tank from Taigen. This is my first one. I've never done R/C tanks before.
The instructions are pretty rough.
There is no indications on how long I should charge the battery. It has an AC adaptor and I could easily see how to plug the battery into the AC charger. But there is no indication on how long I should charge the battery or an indication on over charging.

So does anyone know what I'm doing here?
How long should I charge the battery from the AC adaptor and how do I keep from over charging?

Thanks,

M

Thanks so much for the reply!!


OK I will upload the picture but I think it drove itself back onto the sprocket because it appears to be fine now.

Also the battery is a 7.2V battery.

2 more questions:
(I'm discovering this stuff as I go)

It has an airsoft gun in it but the bb's just roll out of the barrel when I fire it. I don't even know how to get to the gun to fix it. And I guess I don't know how to fix it when I am able to access it.

It said it was a 2 speed drive on the advertisement. Well, how do I switch gears?

7.2V battery

Charge time depends on cell type & charger rating

If Taigen ship like Heng Long then good chance you have basic crap gear
1700 or 1800mAh Ni-CD rechargable battery with about 20-30min run time

upgrading to Ni-Mh type with higher mAh will increase your playtime
example I'm running 4600mah 7.2v Ni-Mh

Wall Charger will be 400ma or 500ma rated
approx 1.5hr -2.3hr charge time

again upgrade to a real one
The Ansman ACS 67P+ is a microprocessor controlled charger for NiCd & NiMH RC battery packs with 6 or 7 cells (7.2v - 8.4v).

Cheers for now

No Gear Shift ( No Stick Shift ) 2 speed = fast & slow in both forward & reverse direction, non 2speed was Fast & dead Stop

BTW- its a Shida 2000 mAh battery.

I was worried about over charging. What if I leave it on the charge too long? Will it damage itself?
