Industry Drilling hole in battery terminal
Used to drill, and weld, battery terminals and cables all the time when I worked on electric/hybrid vehicles back in the ''70s. Definitely use a variable speed drill, and go slow. Lead will grab the bit big-time, and rip the drill right out of your hand. I have the scars to prove it. Regards, Ray L.

6 Frequently Asked Questions about “Can the screw holes of lead-acid batteries be welded ”
How does welding affect a battery?
Thus the welding method has a minimal impact on the battery as there are no catalyzing reactions in the battery caused by the heat. On the other hand deformation may occur if too great of a welding force is applied by the electrodes. This deformation may alter the temperature distribution and hinder the current from flowing the shortest path.
Can a battery cell casing be welded?
The findings are applicable to all kinds of battery cell casings. Additionally, the three welding techniques are compared quantitatively in terms of ultimate tensile strength, heat input into a battery cell caused by the welding process, and electrical contact resistance.
How do you Weld a battery?
The search was then performed using Uppsala University's Library database and Google scholar which cover a wide range of articles and sources. Three methods for welding batteries were given in the template, being laser beam-, ultrasonic-, and resistance spot welding.
Which welding techniques can be used for connecting battery cells?
Brass (CuZn37) test samples are used for the quantitative comparison of the welding techniques, as this metal can be processed by all three welding techniques. At the end of the presented work, the suitability of resistance spot, ultrasonic and laser beam welding for connecting battery cells is evaluated.
Can keyhole welding be used on battery tabs & connector bars?
Furthermore, battery tabs or connector bars with a thickness of several millimeters can be joined by keyhole welding , . Especially for metal surfaces, the reflection of the laser beam is problematic, because it can damage objects in close vicinity.
How does resistance welding affect a battery cell?
4.1.2 Effect on the battery cell Small-scale resistance welding is often the preferred method for joining Li–ion batteries into battery packs. This process ensures strong joints with an almost complete elimination of the heat impact on the joined workpieces during a short time.
