Best batteries for UPS

[Downaski]

Both my UPS (Uninterruptible Power Supply) batteries have died. What are some good batteries for UPS that are durable?

Btw, I am also considering solar for power backup but atm, it seems a big investment.

Hi there!

When choosing durable batteries for your UPS, there are a few solid options to consider.

Sealed Lead Acid (SLA) batteries are a popular choice because they’re reliable and affordable. Brands like APC and Exide have good reputations, and you can usually find them at most electronics stores or online retailers.

If you're looking for something with a longer lifespan and maintenance-free, Absorbent Glass Mat (AGM) batteries are worth considering. They’re a bit pricier but offer better performance. Brands like VMAXTANKS and Renogy are known for their quality AGM batteries.

Another option is Lithium-Ion batteries. While they have a higher upfront cost, they last longer and charge faster, making them a great investment in the long run. Companies like Eaton and CyberPower have some good models specifically designed for UPS systems.

If you have a larger UPS setup or need extended backup time, look into deep cycle batteries from brands like Trojan or Deka, which are built to handle longer discharge periods.

As for solar power, it can be a big investment initially, but it often pays off over time with savings on your energy bills. Plus, there might be tax incentives available that can help offset the costs. If you’re interested, you could start small with a solar generator or a few panels to see how it fits your needs before going for a larger system.

How much do Lithium-Ion batteries cost? Any rough estimate?

[TinyTool]

The cost can vary significantly based on factors like capacity, brand, and intended use. For UPS systems, you can expect to pay roughly:

Small lithium-ion batteries (around 12V, 7Ah): Typically between $100 and $200.
Mid-range batteries (around 12V, 100Ah): These can range from $300 to $700.
Larger batteries (for larger UPS systems or solar storage, like 48V): Prices can start around $800 and go up to $2,000 or more, depending on the capacity and features.

Keep in mind that while lithium-ion batteries have a higher initial cost, they often offer longer lifespans and better performance than traditional lead-acid batteries, which can make them more cost-effective in the long run. Always check for warranties and reviews to ensure you're getting a quality product!

Not that bad. Thank you for the information.

Just came to say to remember to recycle your old batteries! You can search to find a local drop off location or if the batteries are APC, this link might help: https://www.apc.com/us/en/who-we-are...ng-options.jsp
