Garden blowers and vacuums with dual battery operation

Operation on two batteries

— operating with two batteries means that the tool simultaneously uses two battery packs, typically from the same series. This is often done to increase power and voltage (for example, a pair of 18-volt batteries provides 36V), as well as to significantly extend the operating time without recharging. Such models are better at handling wet and compacted leaves, cleaning long paths, large lawns, and yards, especially when a single battery "doesn't last to the end of the lot." While the device becomes heavier and requires two functioning batteries, it is convenient for owners of an entire battery ecosystem to use existing packs from other garden tools. Such blowers-vacuums are more often chosen for regular cleaning of large areas and by users who want to achieve almost "mains" power in a completely autonomous format.
