An interesting thing to be concerned about, given average temperature exposures compared to consumer electronics devices with usually inadequate cooling, compared to LiFePo4 in a UPS, which has been my baseline for years now as SLA's age out. -----Original Message----- From: Mark Tinka <mark@tinka.africa> Sent: Wednesday, April 9, 2025 7:47 AM To: Vasilenko Eduard <vasilenko.eduard@huawei.com>; Gary Sparkes <gary@kisaracorporation.com>; North American Network Operators Group <nanog@lists.nanog.org> Subject: Re: [NANOG] Re: Small Capacity UPS On 4/9/25 10:56, Vasilenko Eduard wrote:
Your first 3 UPSes are lithium-ion. I am scared of lithium-ion in the apartment.
In a UPS, even I would be concerned. It's such a cramped space, and Li-Ion are not as resilient as LA when exposed to high ambient temperatures. That does not mean they will catch fire, but it surely means they will age significantly faster. But for a standard home stationery backup, Li-Ion just fine. I'm coming up on 6 years for my deployment, which is housed in my garage. 700Ah battery pack spread across 7x 100Ah 48V LFP batteries. Mark.
