Say half an hour, then 24 V 24+ A supply. Replacing a battery from a battery-operated equipment with a power supply can be tricky. Especially when the equipment uses an electric motor. The problem is that an electric motor can draw very large startup current - it can be as 10-20 times the nominal for a couple of seconds.
A battery is able to supply that current, while a typical power supply with overcurrent protecton may latch or enter hiccup mode, from which it cant escape. First of all you need to determine the nominal motor current and the maximum current. The maximum current flows when the motor is mechanically overloaded.
Many devices have built-in batteries that are either very difficult or impossible to replace. If you own a laptop with a built-in battery and want to replace it, you are better off letting professionals take care of it. There are many companies that specialize in such work.
This sort of replacement is feasible with the new lithium-ion cells as well as with the older NiMH batteries. Repairs can nevertheless only be successful if the problem is really caused by the battery cells and not defective electronics. We recommend having a specialized workshop carry out such repairs.
Completely disassembling the device to get to the battery is a lot of work, even for professionals. Replacement by a specialist can cost 90 euros or more in this case. How long does a laptop battery last? Although battery runtime differs from device to device, most laptop batteries should last at least 3 hours.
With a new battery, the device will work like new. Look for a suitable battery and install it yourself, or give the device to a workshop without further ado. Once the battery is installed, all you have to do is charge it and then you can already make full use of your device again.
