What does “Multi-Ah” mean?
We often come across physical units in everyday life without understanding exactly what they mean. The “Ah” stands for “ampere hours”, which is a unit of electrical charge. It indicates the amount of charge a (rechargeable) battery can hold, i.e. its capacity. The number of ampere hours indicates how long a battery can be used before it needs recharging. The higher the capacity, the longer the battery will work. The actual time for which the battery can supply current depends on the user and environmental factors.
At Einhell, we use “multi” to refer to a battery that can operate with more than one capacity. Einhell Multi-Ah batteries can switch between the two available amounts of charge at any time. Our range currently includes batteries that can be switched between 4 and 6 Ah and 5 and 8 Ah, respectively. The voltage remains unchanged at 18 V, no matter which capacity setting you select. In this article, we will explain exactly how this switchover works.
