4 best back up batteries

Back-up batteries, in the context of generators and portable power for outdoor use (related to Patio Lawn Garden), are crucial components that provide electrical power in case of power outages or when you need a portable source of electricity. Here's what you need to know about back-up batteries:

Generators: Back-up batteries are often used in conjunction with generators. Generators are devices that convert mechanical energy into electrical energy. They are commonly used as a back-up power source during power outages or in outdoor settings where access to electricity is limited. The back-up batteries in generators serve to start the generator and provide initial power before it stabilizes.
Portable Power: Back-up batteries are also used in various portable power solutions. These can include portable battery packs, power stations, and solar generators. They are designed to provide a source of electricity when you're away from traditional power sources, making them ideal for camping, outdoor events, or emergency situations.
Patio, Lawn, and Garden: In the context of Patio Lawn Garden, back-up batteries can be used for various purposes. For instance, battery-powered lawn and garden tools, such as lawnmowers or trimmers, rely on back-up batteries to provide the necessary power for operation. Additionally, outdoor lighting systems, like solar-powered garden lights, use back-up batteries to store energy collected during the day for nighttime illumination.
Types of Batteries: Back-up batteries can come in various types, including lead-acid batteries, lithium-ion batteries, and even specialized batteries designed for specific purposes.The choice of battery type often depends on factors like capacity, weight, and intended use.
Maintenance: To ensure the reliability of back-up batteries, regular maintenance is essential. This can include checking and maintaining the battery's charge, cleaning terminals, and replacing batteries when they reach the end of their lifespan. Proper maintenance helps extend the life of the battery and ensures it will perform when needed.
Safety: When working with back-up batteries, it's important to follow safety precautions to prevent accidents. This includes proper storage, handling, and disposal of batteries, especially in the case of lead-acid batteries, which can be hazardous if mishandled.

Back-up batteries play a critical role in providing reliable and portable power solutions for both indoor and outdoor applications. Whether you're looking for a source of emergency power during blackouts or seeking a convenient way to power your outdoor equipment and lighting, understanding the role of back-up batteries is essential for making informed decisions.

User questions & answers

Question:	weird Q: a recent outage trapped elder lady in her power recliner. can this be used
Answer:	We have a dual electric recliner sofa. After being temporarily "trapped" during an power outage, we purchased the APC UPS, 600VA BE600M1 APC UPS Battery Backup system. This week we had a 3 day outage, and the UPS worked like a champ. A must have for anybody with electric recliner chair or sofa.
Question:	How long will it power my system while the power is off
Answer:	I had my desktop computer, 2 monitors, and my modem/router combo plugged into the ups battery power. It lasted less than 20 minutes when the power went out, and there was no additional warning when the battery was about to shut off. It just had this intermittent double beep for about 15- 20 minutes, then bang, everything off. Pretty disappointed. I guess you get what you pay for.
Question:	How often does the battery need to be replaced
Answer:	I have had APC batteries last 7-8 years, the shortest was 13 months (12-month warranty, figures!). I have bought replacement batteries from other vendors, don't last at all. I had a beautiful APOC SUA1500, Batteries Plus sold me 2 x SLA batteries duct taped together (yes, literally) and they were NOT made for a backup power suppl;y as they stated, leaked, corroded the entire inside of my very expensive unit! I certainly regret that decision! Batteries Plus said they had the APC batteries, but when I got to the store they did not, ordering them, would take a long time, so I tried their option - will NEVER shop at Batteries Plus again! Just yesterday I had one APC battery die. Bought new unit Dec 17, 2017, today is March 31, 2020. Just over 3 years, their average. No complaints.
Question:	Does it have ethernet ports
Answer:	No, and generally you'll want to avoid surge protectors or UPS's with built in surge protectors that have multiple ports (i.e. coaxial, Ethernet, phone) since these devices turn on at different voltage levels. So once a surge comes in on the LINE (HOT) side of the AC outlet and the voltage has reached a certain level, the surge will be directed to both the NEUTRAL and the SAFETY GROUND, but as soon as that happens, some of the surge makes it's way into the COAX, ETHERNET, and PHONE ports and if you have something plugged into those ports then it goes into the devices. A recent study (see: http://incompliancemag.com/article/lightning-surge-damage-to-ethernet-and-pots-ports-connected-to-inside-wiring/) confirms this. The best place to secure PHONE, and COAX connections is where they enter the house and where they can have a short (less than 10 foot connection to a buried GROUND ROD). If you secure phone & coax at the service entrance and protect your electronics with Type 3 Surge Protectors you won't need to secure the Ethernet connections.Also, it's not a good idea to rely on the Surge Protector inside a UPS as those have a higher clamping voltage generally in the 650-800 Volt range and that means until the voltage reaches 800 volts, your electronics is getting zapped. You can't plug a UPS with an MOV surge protector into an existing MOV based surge protector for compliance (safety) issues, but you can plug a UPS with an MOV surge protector or an MOV surge protector into a Series Mode filter since the filter does not rely on sacrificial MOV's. The Series Mode filter starts to work at 121.4 VAC on a 120 VAC line and it totally eliminates the surge instead of diverting it and hoping the surge can make it's way back through your house wiring to the buried ground rod from the main electrical panel.

Question:	How long does the battery last
Answer:	I just purchased mine but from past experiences it should last 5 years and you can use it without a battery but without the software or battery back up.
Question:	How long will the 425 model run a 5 watt device
Answer:	My UPS 650 software says I have up to 35 minutes when hooked up to a desktop monitor and modem. I would think the 425 would be 20 minutes or less if the same power consumption is demanded. 5 watts isn't much, so it should last longer.
Question:	There really has been no direct answer to the question about disabling the alarm (forget installing software). Is there a way by "holding" the button
Answer:	If you read the manual they make available on this page for the 600AH batteries and up, you will see that you CAN TURN OFF ALL ALARMS! I would not recommend turning off the LOW BATTERY alarm, but you can turn that off too! Not sure about the 425 though. Though, you can look up the manuals for all of them as the not only make them available but ENCOURAGE you to read them BEFORE you buy them!! Kinda like that kind of information being there.
