A UPS battery lives a strange life: years at float voltage doing nothing, then a few minutes of violent discharge on the worst day of the building’s year. XD Battery supplies batteries across the full span of that duty — the company’s range includes UPS systems themselves from 500 VA to 800 kVA, and the battery lines that feed them, from small-office blocks to plant-room strings. The documented anchor model is the 12V 150Ah UPS battery: a deep-cycle-capable sealed block with good sealing performance, documented at a one-piece MOQ with a three-year warranty, listed for UPS, solar and standby service.
UPS battery selection is a sizing exercise before it is a shopping exercise. The load (kVA and power factor), the required autonomy (minutes at full load), the UPS DC bus voltage and the discharge rate together determine the block count and capacity — and high-rate discharge means the nameplate amp-hours are never the usable amp-hours. Our UPS battery replacement guide works through the arithmetic and the replacement discipline; our team applies the same method to your UPS model when you inquire.
The replacement reality
Most UPS batteries are bought as replacements, not first fits — and replacements are bought late, under time pressure, one string at a time. The defences are boring and effective: replace strings as matched sets, record installation dates, and test under load annually. Blocks from this range serve exactly that trade; the documented 12V 150Ah UPS model carries a one-piece MOQ, other models are confirmed at quotation, and the manufacturer answers the phone.
Can I replace one failed block in a string?
In an emergency, yes; as a policy, no. A new block in an aged string is overcharged while its neighbours undercharge. Matched-set replacement is the professional standard — see the replacement guide.
How long should a UPS battery last?
Design float life and real life differ with temperature above all. The documented models carry a three-year warranty; service life expectations for your conditions are part of the quotation conversation.
