Note carefully, the Boss PSA-240 9V power supply must have the centre pin negative. This is very important. Many generic 9V power supplies have the centre pin as positve, and this would damage any Boss pedal that requries a PSA-240. You can buy a generic 9V power supply. Just make sure the centre pin is negative, and the rating is at least 0.5A.

Invented by the French physician Gaston Planté in 1859, lead acid was the first rechargeable battery for commercial use. Despite its advanced age, the lead chemistry continues to be in wide use today. There are good reasons for its popularity; lead acid is dependable and inexpensive on a cost-per-watt base.

At its most basic, battery voltage is a measure of the electrical potential difference between the two terminals of a battery—the positive terminal and the negative terminal. It''s this difference that pushes the flow of electrons through a circuit, enabling the battery to power your devices.

Any use of a battery degrades it. In the end this is creating less reduction in capacity compared to disconnecting the power adapter and allowing it to be used on battery power. The battery is also needed to have full capabilities. A battery can supply considerably more peak current than the power adapter is capable of supplying.

It's main task is to provide power from an internal battery if the mains supply fails. A laptop's battery is purely a DC supply with no ripple and noise, so while a battery doesn't condition the power, there is no noise and ripple to remove, so the effect is the same.
A laptop uses power from the wall outlet when plugged in. It charges the battery while connected. The laptop operates on AC power when the battery is fully charged. It does not consume battery power in this mode, except during a power interruption. Battery health is another vital aspect. Modern laptops are designed with smart charging technology.
