![]() Vs APC units that you may not know have a 'dead' battery until a self test fails (which only happens on power up, not useful for 24/7 'on' applications) or when there's a power issue and the terminal just dies. The battery is somehow 'part of the circuit' even when running on mains power. The only problem I've ever had with CyberPower UPS units is when the voltage dies across the battery the UPS dies with em. Luckily I had a spare UPS I could immediately deploy, but the QC issues (even if it was an isolated incident) and lack of response has been entirely frustrating, especially considering the potential for damage/injury this could have caused! I have called multiple times since then, and started a claim on their website, but still no return call or email yet. ![]() The claims department was apparently not taking calls, so I spoke with a general CSR, and left a message. I called CyberPower to start a claims process on Friday. Luckily I had a large bag of baking soda to neutralize the acid before any major damage occurred, but this was definitely a surprising and somewhat scary situation. I pulled open the battery compartment before I realized that the SLA batteries were no longer 'sealed', and had leaked battery acid all over the UPS case, and now my hands and arms. I pulled the unit to check on the batteries, and noticed there was a sticky substance covering the lower sides and bottom of the unit. ![]() To my surprise, the UPS immediately shut down when mains power was removed. Approaching the height of fire/power outage season, last Thursday night I ran a load test and pulled the UPS to check on the battery health. I have a 2.5 year old CyberPower CP1500PFCLCD sitting on a shelf at the bottom of my rack, powering two servers and a switch.
