I've just bought a wired Geared Motor 12VDC 8RPM which I'd like to use as part of a rotating spit set up, and wonder what would be the best battery to hook it up with and use for maximum output; I did see info on this elsewhere, but lost the link on my browser crash, so just hoping to get some advice on this to ensure I don't burn it out!

Thanks!

Without the rating of the motor it is not possible to help.
what is the motor rating, it will (should) be on a plate or sticker on the motor.
With this info we can help
 
for example if your motor is about 1 amp/12watt will run for around 6h30-7h on a 7.2 ah battery

you will only burn out the motor if you overload it
12v is the engine and ah is the fuel tank
 
Hi, and thanks for the replies...it's this one I've got:

you need to know the power consumption to know the battery required
but on such a small motor a 7 ah battery would should last the average bbq length off around 4hrs but purely a guess without the power consumption figures

Indeed, but whether such a tiny motor even with its gearing, would be able to turn a significantly loaded BBQ spit is, I would have thought, a less certain matter.

a gearing off several hundred to 1 even several thousand to one suspect it will have the power if not the strength in the gearing

Very unlikely. AH capacities are quoted at the 20 hour rate, i.e. your 7.2AH bayberry would last 20 hours at 0.36A. At higher loads the capacity drops.

Gearing will not increase the power, only the torque, but you may be right. However, I definitely would not out any money on it!

i fully agree unless it is specifically made for the purpose off rotating several kilos of badly balanced meat it will fail
 
Plus the heat travelling up the spit shaft will melt the plastic gear wheels that model motors invariably contain
 
... a wired Geared Motor 12VDCThanks!..

You can not burn it out unless yo give it more than 12V.
We can't say how much current or power it needs. The data plate you showed missed that important detail out.

Post a picture, and we'll have a guess. Or have another look at the spec's and if there are any figures stating Amps or Watts, or even HP, then reply.

are you saying the battery would be far more inefficient at 1 amp ??
i have made the assumption off 3-10% loss at 1 amp ??

Yes.
