Long WPS40-12 in everyday use

Data centres replace whole strings of batteries on a schedule. Photograph the terminal type and connector positions before removing the old blocks. A UPS that shuts down seconds after a cut needs new batteries.

How AGM batteries work and how to look after them

Open up an AGM battery in your imagination and you would find the acid soaked into thin glass-fibre sheets squeezed against each plate. Alarm panels and UPS units are classic homes for small AGM blocks. Do not mix AGM and flooded batteries in one bank.

Before you order: a quick checklist

✓ Measure the space available: the case takes up 199 × 166 × 171 mm, and a few millimetres too many can stop the hold-down from closing.
✓ Stored energy reserve: 40Ah. Going much lower than your current battery can leave you short on cold mornings or long stops.
✓ Check that the alternator or controller suits AGM.

Common questions about the Long WPS40-12

Will the Long WPS40-12 replace my old battery?

Compare four things: the voltage, the amp-hours, the outer dimensions and which side the plus post is on. If all match, or capacity is slightly higher, it is a suitable replacement.
