UPS batteries

Discussion in 'Tech Talk' started by CitizenOfDreams, Mar 24, 2013.

  1. I just found out (the hard way, naturally) that the batteries in my UPS are dead.

    Can anyone recommend a good battery brand that won't cost me more than a new UPS? Any experience with "ChromeBattery"?

    Go to your local batteries plus. The battery is around $35 if it's the same one I have.

    This if you have one. Finding it for less on line can still cost more with shipping.
  4. They are $39 each at my local BatteriesPlus. That's almost as much as a new UPS with batteries. And I never heard of "Werker" brand either; it's probably made in the same province of China as the "ChromeBattery" that's $18 shipped. :dunno:
  5. Well, I rolled the dice. Bought two "Chrome Battery" brand SLAs, $36 for both of them with free shipping. Hopefully I won't get too many power blackouts until they arrive.

    How much was your UPS? Must be a cheap one. Mine are all around 100. But they are APC.
  7. A new UPS with similar specs is around $120. Doesn't make much sense to buy $80 worth of batteries (it takes two) for the old one.

    Try Amazon, Ebay or other online sources, you can usually get them cheaper there - and you might find them on Amazon with free super saver shipping to.

    Don't know what size you need but here is one from Amazon:

    $18.99 and free shipping.

    "open source" UPS ? :tongueout:
  10. It's more like a pirated copy of a Tripp-Lite UPS. :supergrin: But it worked great until the batteries finally died after who knows how many years.
  11. So, I got my new "Chrome Batteries" today. They seem to work fine, except for one little problem - the stupid UPS cycled the power on and off when I plugged them in. I thought that sun-on-a-beach was supposed to be hotswappable! :faint:
  12. I've heard that you should actually replace the entire UPS every few years anyway.

    If it takes a few hits from power surges, it weakens or eliminates its surge protection capabilities.

    I use APC and have good results with them. A basic model for a desktop/laptop or two can be had for like $40-50 online.

    I'd just replace the whole thing, if you didn't already purchase the new battery.
  13. I'm not really worried about surges. A UPS is not going protect my equipment from something like a direct lightning strike anyway. And for less serious overvoltages most power supplies have their own MOVs.

  14. Over the past year, I've seen a lot of equipment damaged when the power comes back on after a brief outage - not even any storms involved, just a simple power outage.

    I'm paying more attention to ensuring my clients have real surge protectors - not just cheap power strips - and battery backups when necessary.

    I have two different UPS's. One is a APC 1000 UPS feeding a brand X 300 UPC that handles my office. The UPC is rated at 1000 Watts for 15 minutes which means it has small batteries in it that are going gonzo to keep things running and will shut down in 15 minutes or less. In my Ham Radio Shack I have an APC 1500 UPS that is fed by two Group 27 Batteries in series (24VDC UPS) that will run things for 24 hours. Most of what you get off of the local stores will work for 15 minutes and that is all. Beep, Beep!
  16. 15-minute discharge is a perfectly acceptable working mode for lead acid batteries. :dunno:
    That's what a typical home computer needs - 15 minutes of runtime to give you enough time to reset a tripped breaker or to save your work and shut down. Most home users wouldn't want to pay thousands of dollars for a real UPS, or keep a pair of car batteries on the shelf.
