My Dynamix 1700 UPS no longer functions as a UPS - if there is a power outage, it just dies.

I am assuming the battery is dead and needs replacing. Does anyone have a good source for such a battery?

itpower.co.nz is the best place to go for batteries.

Cheap UPS devices including the Dynamix brand are IMHO a fire hazard and should be sent to the recyclers ASAP. (I like the Dynamix brand otherwise.) Source: My own experience of cheap UPS smoking and an Industrial Electrician friend.

Had my batteries go also. Pieces can vary from about $35 to $60 depending where you go. Also I found there are two types on connector T1 t2 they vary in size

Just wander down to Radcliffe or similar... also stick a date on the side of your ups so you know when you changed them. I find at 18months they are fine..ish and at two years they are completely stuffed

I'll never buy a dynamix ups again. When my line voltage drops below 220v, the dynamix ups boosts the voltage to 258v.

All it powers now is my modem and switch. My server gave me hell hen it was on it.

I've had a dynamix UPS burst into flames once however I was trying to run a vacuum cleaner off it outside.

Protip: Never run a vacuum cleaner off a UPS unless if you want to intentionally destroy a dynamix UPS.

All good tips, but this one is the best!

I've seen 3 Dynamix UPS overheat and burn out, one was so hot you couldn't touch it. A fire hazard for sure.

Never buy a cheap UPS. It's worth spending the money on a better quality one

apart from needing to replace batteries ive never had an issue with the 10 dynamix ups we use on the ship for the desktop PC's. The ship is a hugely more demanding environment for the ups thank what you have at home. the input voltage varies from 210-240v, there are brownouts when compressors start anywhere up to 30 times a day, at least once or twice a week its running off batteries, and once a month it would have a complete discharge due to damage control training where there is no power to the ship for about an hour or so.

I dont know why so many of you are having issues, unless you are overloading it or its getting way to hot where you keep it.

@geektastic you need to find out what size batteries it uses then just jump on google and find a local supplier for them. it may or may not be easy to replace in the 1700w model, i know they 400w models you have to pull a lot of it apart to get the battery out.

I've had two Dynamix UPS over the years. They both last about 3 years then died.

I just bought a new UPS yesterday, "Blazer III" 1200-something. I charged it overnight and will install it this morning.

I use UPS for small but important powered devices like my mains-power phone, my router and my NAS (22.5 watts). It should keep everything running for a couple of hours. Usually good enough to keep me online though any outage.

I've been passive. I pay about $150 for these things and after 3 years I'm ready for an update anyway.

+1 Get a good one, or don't get one at all. The cheapest ones are worse than useless, and sometimes a safety hazard.

That is impressive, I would expect you have to replace the batteries pretty frequently? I've had bad times with Blazer, Dynamix or other cheap brands and will always pay the bit more for APC et al now.

EDIT: Installed my new Sentry Lite 12V DC UPS last night with an old 14AH battery, powering my Fritz!Box and Meraki wireless AP. Nice piece of kit, I don't think the 14AH has much life left in it after my last DIY UPS over-discharged it, but I tested it for two hours before work this morning and was still up before turning mains back on

APC had a basic "Battery backup" at PB Tech. It didn't say "line interactive" anywhere on the box. Is there a class of devices that are manual backups and not line interactive? It was pretty cheap - about $110.

Yeah the cheap ones are offline and just switch in really fast when the mains fails or drops below a certain voltage. I use a couple of the 'giant power board' models on my broadband gear, cordless phone, and our iMac at home, configuring the software to shut the computer down after 1 minute without mains power but it leaves the mains on for the cordless phone and router.

get about 3 years out of them, but don't replace the battery's just replace them as they are only about $70.
