Wait. You threw away the charger but managed to hang on to the manual?
What kind of frickery is that?

For fricks sake, it was a joke, not a serious reply 
It didn’t need clarification .

Are you sure that battery is still good?
I would use a voltmeter on ohms to figure out the polarity of the plug. Most of the time, the center pin is positive. Hook one lead of the mti.eter to the ground on the battery and then the other lead to the outside of the barrel connector on the car. If you have a dead short then the center pin is positive.
Pretty sure the charger would work on either 7.5 or 9v but most of these toys don't have the circuitry built in to regulate the charge to the battery so leaving it plugged in longer than they recommend may ruin the battery capacity due to overcharging.

Yeah I can’t say I have ever seen something need 8 V
If he is feeling handy he can get an adjustable voltage regulator and a potentiometer and solder up an adapter to step it down to 8 V

7.2 is the optimal charging voltage for a 6 volt battery.
Posted on 2/15/18 at 8:24 pm to MiloDanglers
that'll work. just make sure you have the charger set to 6v

You can also just get a short piece of picture hanger wire, add a large paper clip to the loose end and leave it in contact with the charger. Set the charger on 9v and it will bleed some charge off down to about 8v.

nah, a 6 volt battery is basically dead at 6 volts. no different than your phone, 3.7 volt battery but the charger is 5 volts.

Google the brain or super brain battery charger. The one I had would read the battery’s requirement and charge at the rate it determines. We used it for r/c battery charging.

Don’t know if your car will charge but the house will definitely burn down if you plug that in.
Posted on 2/15/18 at 11:03 pm to MiloDanglers
Buy the exact same car again and when one battery is down the other will be still rolling.
Duh.
Duh.

I just solved the same issue last weekend with an old laptop. The charging port had been out on it for years, and never had it replaced so I decided to try bypassing it just to see if it would work. Cut the end of power adapter, which will have a positive and negative, and ran each of those to a 4pin molex(had plenty from old PSU's), then took enough of laptop apart to reach charge port where I removed port and then ran wiring(positive and negative) to another 4pin molex. Works like a charm.
You just need to make sure that whatever adapter you use, if you use a different one not made for that product, pushes the right amount of voltage.

Highly technical?
Posted on 2/16/18 at 7:14 am to MiloDanglers
The DC output nees to be 8V and as near 1000mA as possible.

My wife keeps manuals for EVERYTHING and never throws them away. I went thru our file cabinet a few months ago and found at least 20 manuals for items we no longer have. Her reply was "it doesn't hurt to keep them". What?
Never has submitted a warranty card though.

Check ebay for replacement charger. Some poor little guy in China is turning these out by the thousands every day...
