7 best battery for cyberpowers

CyberPower is a well-known manufacturer of Uninterruptible Power Supplies (UPS) and related power protection products. Batteries are a crucial component of these UPS devices, as they provide backup power in case of electrical outages or fluctuations. Here's what you should know about batteries for CyberPower UPS systems:

Types of Batteries:
- CyberPower UPS units typically use sealed lead-acid (SLA) batteries or lithium-ion batteries.
- Sealed Lead-Acid Batteries: These are the most common type of batteries used in UPS systems. They are reliable, relatively low-cost, and suitable for standby power applications.
- Lithium-Ion Batteries: Some high-end CyberPower UPS models may feature lithium-ion batteries, which are known for their longer lifespan and lighter weight compared to SLA batteries.
Battery Backup:
- CyberPower UPS systems provide battery backup power during electrical outages. This allows connected devices such as computers, servers, and networking equipment to continue running temporarily, giving users time to save work and shut down systems properly.
Runtime:
- The runtime of a CyberPower UPS depends on factors such as the UPS model, the load (the total power demand of connected devices), and the capacity of the battery.CyberPower often provides runtime estimations for specific models and loads to help users determine how long their devices can run on battery power.
Battery Replacement:
- Like all batteries, those in CyberPower UPS units have a limited lifespan. Over time, their capacity can degrade, reducing the backup runtime.
- CyberPower typically offers replacement battery kits that include new batteries and instructions for safe replacement. Users can extend the life of their UPS by replacing the batteries when needed.
Maintenance-Free Batteries:
- Many CyberPower UPS units come equipped with maintenance-free batteries, meaning they do not require periodic electrolyte refilling or other maintenance tasks. This adds to the convenience of using these UPS systems.
Testing and Self-Diagnostics:
- CyberPower UPS units often include self-diagnostic features that periodically test the battery and alert the user if any issues are detected. Regular testing ensures the battery's readiness for use during power outages.
Compatibility:
- When replacing a battery in a CyberPower UPS, it's essential to use a compatible battery kit recommended by the manufacturer to ensure proper fit and performance.
Warranty:
- CyberPower typically offers warranties on their UPS systems, which may include coverage for the batteries. Be sure to check the specific warranty terms for your UPS model.

In summary, batteries are a critical component of CyberPower Uninterruptible Power Supplies (UPS). They provide backup power during electrical outages, allowing connected devices to continue running. Understanding the type of battery your UPS uses, its runtime, and when to replace it is essential to ensure reliable power protection for your electronic equipment.

User questions & answers

Question:	I am in doubt between CP1500PFCLCD and CP1500AVRLCD for my Home Theater. Which one will fit me better ? Do I really need the PFC feature
Answer:	Yes, you do need the PFC feature. I have both a CP1500PFCLCD and 2 CP1500AVRT's for my desktop (see the first and last 2 minutes):https://youtu.be/pwNJto6VWE8I connected my Altec Lansing 2.1 speakers to the CP1500AVRT. While I had a power outage, the speakers would not work. They only worked when I used the CP1500PFCLCD. I believe it has something to do with the way the cheaper CP1500AVRT outputs power. Also, the way the cheaper UPS's output power may damage the sensitive electronic components of your stereo and TV. This happened to my TV which was connected to another cheaper UPS, a 500VA Blackout Buster. I never found out why the TV was damaged..
Question:	I noticed the 900 watt rating, will this unit protect and back up a computer with a 1200 watt internal power supply
Answer:	IMPORTANT ---> READ: With my new desktop bought last year, the original computer power supply was a ThermalTake 800 watt unit. I knew from the running wattage draw that was/is a nominal 150-165 watts or so, this 800 watt OUTPUT CAPABLE- NOT WHAT IT DRAWS FROM THE WALL, ThermalTake would shut down my computer when the power bumped off or during a self test. I thought my original 900 watt Cyberpower sine wave UPS would/should handle this relatively LIGHT LOAD of the 165 watts if/when it transferred to BU power, but, it DID NOT. SO, I returned this 900 watt CP UPS for the 1500 Pure Sine Wave unit thinking, hell, NOW this sob should not shut down my computer if/when a power bump occurred. AGAIN, even with this 1500 watt CP UPS, the damn computer kept shutting down. After lots of research I discovered that this ThermalTake model, as well as their other models, DO NOT HAVE ANY CURRENT LIMITING CIRCUITRY that limits the INRUSH CURRENT when the computer - power supply first kicks on. I returned and bought a EVGA 650 G5 that DOES HAVE INRUSH CURRENT LIMITING. After replacing the POS ThermalTake wit this PROPERLY DESIGNED PS - EVGA, my computer has never shut down during power bumps or self tests. SO, lesson here is that these computer power supplies are rated as to WHAT POWER THEY CAN OUTPUT - NOT AS TO WHAT THEY DRAW from the wall outlet. As mentioned before my desktop only draws a nominal 165 watts or so and with using a better quality, PROPERLY DESIGNED computer power supply, EVGA for one, I could have kept/used the original 900 watt CP UPS without any issues.... IF you are still having any transfer issues with your UPS not switching over and shutting down your computer, LOOK AT THE DAMN computer power supply as the definite culprit......
Question:	The Box says CP1500FCLCD ADAPTIVE SINE WAVE . The spec sheet says "Output Waveform" ADAPTIVE SINE WAVE
Answer:	I am familiar with oscilloscopes and plugging one up to a wall outlet can be frightening. My problem is not my hydroelectric, but while the frig and electric range/oven, have their own circuits, I have just too much stuff on a couple 15 AMP circuits, and the microwave and toaster oven and laser printer can brown out a circuit and my UPS will kick in. The Automatic Voltage Regulator will pull more of the brown out (lower voltage) electricity until the UPS saves the day. Even when the UPS does not kick in, I'm sure the AVR is doing my electronics a marvelous service. The brief sag in voltage when a motor or laser, or the same thing, a laser printer starts up should be avoided. Never, ever, by the way plug a laser printer, refrigerator, etc. into this UPS!!! The pure analogue sine wave of the falling water generator v. "adaptive sine wave" of this UPS, reminds me of when CDs first came out, eventually to replace vinyl records. The CD's were condemned as they have digitized the nigh infinite bumps and valleys of a vinyl record. Personally, I could never hear the difference, while tapes are so linear and jumping between tracks meant feet of tape. Recording was very difficult to mix. Sorting out ones music was bulky, and time consuming. Probably, the CD's lack the dynamic range of vinyl records, but let's remember, CD's were the first widely sold and owned digital media. Another myth busted is that digital cameras would never replace film. Every other UPS I had bought was short lived, and this unit, of which I use three, is a marvelous buy for me. This is a more expensive version, but unless your corporate requires the extra certification for the more expensive model, get this one. And I LOVE that if you overload this UPS, the unit will not let you do it. Let's say we wanted a "PURE (ANALOGUE) SINE WAVE?" Well, the UPS battery could spin a generator, which is mechanical and will require maintenance and will not kick in soon enough. This will show my age: once upon a time Dove soap advertised that it was 99.44% pure soap. Some chemist tested the soap, and when all the percents of the compounds were added together, 0.56% was unaccounted. We should not have said that Dove soap was pure soap and they chose to advertise that Dove is 99.44% pure soap, which made it a mysterious, almost pure soap, which when rounded out, was 1% MIA. Nowadays we should say that Dove soap is ADAPTIVE SOAP. I have an electric piano hooked up to one of my UPS. I have my NAS hooked up to another. I have my TV and desktop computer and game console hooked up to my third. (I am not going to run the desktop and game console at the same time.) These UPSs are quite far from each other. I believe ALL my electronics, apart from the mechanical hard drive in the game console, will outlive me. When there is a brown out, all the electronics lose the battle to draw more current. This UPS feeds within tolerances, EXACTLY what is PERFECT for my electronics. Final Bonus Advice: This UPS has electronics, and using the battery, charging the battery, generates heat. The unit does not have a fan and doesn't need one, but it needs to breath as in ventilate. Do not put this unit in a cabinet and close the door. HEAT IS THE ENEMY OF ELECTRONICS! Semiconductors are semi passing the electricity along, and semi producing heat. Besides surge protection, and besides the UPS not allowing the equivalent of pulling the plug, this UPS has two more fabulous features, which will benefit your electronics: 1. The Automatic Voltage Regulation means that small brownouts and spikes will be addressed. 2. The ADAPTIVE SINE WAVE is as pretty as the oscilloscope of the original Outer Limits. 3. (The USB charging ports are way cool, nifty, dynamite, keen.)
Question:	What is the power draw of CP1500PFCLCD with no attached devices? Competitors are 100-130W, but "save up to 75% energy" doesn't tell me anything
Answer:	I watched a couple Youtube video reviews where people used meters to check and it seems there is between 11 and 16 watts in over head while the battery is charging. If the unit is turned off and still plugged into the wall outlet the battery will still charge to keep it at 100% but not actually output power to it's outlets. If the battery is 100% charged then there is no draw what so ever.The only way to know for sure what is going on is for you to actually test your unit to see how much power it is consuming. From what I saw in the video's on Youtube it ranged between 0 and 19 watts, depending on the charge state of the batteries.

User questions & answers

Question:	When my heater or dishwasher first kicks on, my big screen TV shuts off (then comes back on seconds later). Will the 650VA LCD UPS fix this? I live in an old house
Answer:	When a large motorized appliance such as a dish washer or a heater blower turns on, the initial startup draws a lot of current, much more current than it draws after it gets going a few seconds later. A UPS can help prevent such short-term voltage drops. But it us important to size the UPS correctly to the TV size. It is important to find out how much power in Watts, or Volt-Amps is your Big screen TV consuming. Perhaps you can find out on Google, the owners manual or in the back of the TV. For example, if your TV draws 400 Watts. then 650 volt-amp UPS will do. You want your UPS to be rated to be one and a half times bigger in Volt-amps than your TV rating. If your TV draws 500 watts, then get a 750 volt-amp UPS.
Question:	how much time do i have to shut all things off and down
Answer:	It depends on how much of that 510watts you're using according to cyberpower you have10.4 Minutes when using 210 Watts, and 2.15 Minutes when using 425 Watts and probably 1min or less if you're under max loadThe power went off at my house recently for a couple minutes and before i could shutdown my htpc the power came back and my htpc never shut offMind you my htpc is using a 600watt power supply but computers don't use the full wattage, especially if it's idle
Question:	I've had my pc shut down twice since plugging this is and the battery backup has not kicked on. its plugged in thru usb, software is installed
Answer:	Several Power Supply Units are not compatible with this UPS. The reason is that this UPS generates a simulated sine wave when the battery kicks in. Power Factor Correction PSUs automatically shut down when they receive this simulated waves because it doesn't match its internal "requirements" for power.

Question:	Is the battery replaceable
Answer:	I almost bought a brand new unit. I have two EC850LCD and the battery is replaceable. Its as simple as purchasing the correct replacement 3rd party battery, removing 4 screws and the battery connectors. Make sure that the specs of the battery matches the original Leoch SLA. Dimension is 5.9 x 2.5 x 3.7 inches. I replaced with https://www.amazon.com/gp/product/B003S1RQ2S/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1. (ExpertPower 12V 7 Amp EXP1270 Rechargeable Lead Acid Battery). Tested by unplugging from wall and my systems stayed up for 10-15 minutes.
