Chrome Battery went online some years ago. Initially, it manufactured in the USA. Quality control was top-notch. Later, manufacturing was transferred to China, because there no more lead mines in the USA, and to cut costs. Since then the quality control has become unacceptable, at least to me. Some of Chrome's SLA batteries fail after three years, with no discharges between installation and failure.
Service is bad. The last three orders I placed I was shipped the wrong product. Correcting the errors was no biggie. No extra cost but my time and frustration. And, the prices are about the same as better batteries made by superior producers.
Verdict: if the battery is used in a critical application, keep looking!
