UTL and UT battery terminals with threaded studs require a torque of 95 – 105 in-lb (79 – 88 ft-lb). For bolt-thru terminals such as large and small L and Offset S, the recommended torque is 100-120 in-lb (83 – 10 ft-lb).
Does terminal size matter
There is no one size that fits all when it comes to terminals. Regular car batteries often have the well known round post type of terminal, but the negative is slightly smaller than the positive post. They don’t really change size for different capacities.

Can I use a metal wrench on a car battery?
Hi Tom,
The danger from car batteries is not so much electrocution as it is explosion. If you touch both terminals with a metal wrench, for instance, you can create a spark that can ignite hydrogen gas in the battery. That can send pieces of battery and acid flying.
So be careful around car batteries, and if you’re not sure what you’re doing, it’s best to leave it to a professional.
Thanks,
AJ

Final Words
There is no definitive answer to this question as the size of spanner required for battery terminals will depend on the specific make and model of the battery. However, as a general guide, a small to medium sized spanner should be suitable for most battery terminals.
The most important thing to consider when choosing a size spanner for your battery terminals is the width of the terminal posts. You’ll want to make sure the spanner you choose is narrow enough to fit between the posts without touching the sides, otherwise you risk shorting out the battery. Once you’ve determined the width of your posts, you can then choose a spanner size that is comfortable for you to use.
