Is Power-Sonic on Sale? November 2026

Questions and answers

What is the difference between the PS-121000 and the PS-121000U?

The U version carries UL recognition on the cell and is the one buyers pick when an inspector or insurer asks for it. The two are otherwise the same 12V 100Ah sealed lead acid block with the same terminal layout and footprint.

What can a 12V 100Ah battery run?

It suits UPS and telecom backup, alarm and access control panels, mobility scooters, trolling motors, and small solar setups. Expect roughly 100Ah at a 20-hour rate, less when drawn hard. Deep discharges shorten life, so size the bank above your load.

How long do Power-Sonic SLA batteries last?

Typically three to five years in float service at room temperature, less in heat or with frequent deep cycling. Capacity fades gradually, so test with a load rather than trusting voltage alone. Keep them charged and never store them flat.

Does Power-Sonic offer a warranty?

Power-Sonic backs its SLA blocks with a limited warranty against manufacturing defects, handled through the seller or distributor you bought from. Keep the receipt and check the terms for your model, since coverage length varies by product line.

Can these batteries be shipped and returned?

Sealed lead acid blocks ship as non-spillable regulated goods, so some carriers and sellers restrict air shipping. Returns are usually accepted unused and in original packaging, but lead acid is often excluded from free-return policies, so confirm before ordering.

Are there Power-Sonic discount codes?

Deal.ai checks what Power-Sonic products actually cost at every store, so a real markdown shows on this page as a deal as soon as it starts, and each product's page has its price history to tell a sale from its usual price.
