Installation and maintenance tips
Emergency lights in a stairwell have to last their full test duration every time. Note the fitting date on the case. Choosing on size alone and ignoring terminal width leads to connectors that will not fit.
About the technology: AGM
Valve-regulated construction keeps an AGM case closed during normal life. AGM suits UPS and standby systems where a maintenance-free battery makes life easier. A full charge now and then helps an AGM battery that mostly works part-charged.
Before you order: a quick checklist
- ✓ Capacity is 28Ah. Aim for the same figure as your old battery or slightly above, never much lower.
- ✓ Chemistry: AGM. Some vehicles and chargers are programmed for a specific type, so check before swapping.
- ✓ Will it fit? The Long WPL28-12TN measures 166 × 125.5 × 176 mm, so compare length first, then width, then height with the lid or bonnet closed.
