Familiar, Yet Freshened
By John Florian
This is the 3rd ... er 1st of these that I've owned. Probably 15 years ago I'd bought a Best Fortress 750 and it had served me well. I needed another but Best had been acquired by PowerWare and had a migration map to a nearly identical model (PW 5115), which I bought and would describe as the same but with improved battery management and simpler indicators. The PowerWare is now better than 8 years old and still on the OEM batteries.Meanwhile the once trusty Fortress has, either by age or increased on-battery time or poorer quality replacement batteries, I don't know but the replacements just seem to last for fewer years each time, despite always buying the same make/model batteries. Compared to the PowerWare, still chugging along on the OEM batteries, the Fortress now started to irk me every time it wanted feeding. Then a new warning, continuous beep. Consulting manual tells me that it has an internal failure.Time to shop and Amazon doesn't disappoint by offering this -- I'll call it 3rd gen. -- model, now known as the Eaton PowerWare 5115. The "Eaton" part is new and must represent another acquisition, I suppose. I elected to buy it and had it with usual Amazon Prime speed, two-day UPS. I saw one other 'net retailer with a lower price with shipping, but would be shipping across the US to me and I thought about the shipping time. Rather than gamble with the other retailer, I chose Amazon. Smartly as it turned out because now the Fortress was overheating the batteries. A day after I place my order!Once again, this "model" has been improved and now offers USB in addition to the traditional DB9 serial port for monitoring. Also on the back are (4) 5-15 power receptacles arranged 2x2 without enough room for power-packs but plenty for a standard 120V plug. Also there are 2 RJ45 connectors for Ethernet (or phone IIRC). It mostly seems like the good ol' PowerWare 5115 I've come to depend on for just working w/o fuss, but improved.It does have one design flaw that with proper respect can be coped with. There are two batteries, typical small 12V units, shaped like that of a motorcycle's and they are arranged with their bottoms facing each other. This "vertical" part is fine as they are of no-spill design. However the UPS hookup wires consist of one short wire at the front (first off, last on) and another longer wire from the internal rear (last off, first on). This longer wire has to coil up somewhere and tends towards a battery pack guide rail. If you don't "steer" the wire clear purposely you might, while moving the battery pack in/out, damage the wire's protective sleeve and maybe the insulation too.If this 5115 turns out as good as my old 5115, I could only appreciate it more if it came colored black instead and maybe had a simpler LCD panel instead of the discrete LEDs. Maybe in another 10 years!
