Title: battery backup stopped working in a month
Review: The Chinese-made battery in this unit failed in a few weeks after only providing a total of about thirty seconds of backup. I have had similar experiences with power tool and lantern battery replacements made in China; they provide only a fraction of the service time of the Japanese or American originals. I support dozens of cordless items from numerous manufacturers, and I've collected enough bad experiences to advise people to avoid Chinese-made rechargeable batteries when possible.
