    5-STARS and a WOW. Excellent value. Best price I've found. Item was exactly as described. If fit perfectly into my APC UPS BK280. The battery was factory fresh - 4 months old. SLA batteries are considered factory fresh if 6 months old or less. LIGHTNING SHIPPING! Only 48 hours between order and delivery. VERY SAFELY packed - double boxed and padded. Communications were fast, friendly, and very helpful. We had three exchanges and they answered within 24 hours. A+++

  • Good battery for 1, maybe 2, year(s)

    Solid product as advertised. My battery got to the point where it wouldn't hold enough charge to be useful after over a year (maybe 1.5 years) of using my Roomba about once a week. For the replacement, this time I'm eyeing Li-Ion batteries since they are only about twice as much (~$40 currently). If Li-Ion batteries didn't exist, I would probably buy this again.
