It’s too early to write an accurate review yet. After my first charge, I left the house after 45 minutes of vacuuming and it was still going strong. The recharge took more time than I remembered, but that’s ok if the stored charge is good.
The battery has an adapter connector wire, so there is an extra connector to fit in the battery compartment. It does fit! I’m hoping it was a smart buy. Time will give the answer.
