Using it day to day: practical tips
Home alarm panels beep at night when their batteries weaken. Ventilate battery cabinets properly. Mixing old and new batteries in one UPS cuts runtime and harms the new blocks.
About the technology: AGM
Glass-mat batteries are sealed, with small valves that only open if pressure builds up. Leisure vehicles choose AGM when the battery lives under a seat. Old-fashioned chargers without automatic cut-off are a poor match for glass-mat batteries.
Quick compatibility checklist
- ✓ Built with AGM technology: if your vehicle or system was set up for another chemistry, check the charging settings first.
- ✓ Make room for 90 × 34 × 65 mm, including clearance above the posts.
- ✓ Plus post on this one: positive on the left-hand side. Make sure the cable lengths reach.
Common questions about the Fulbat FP4-3.5
Can one person lift this battery?
It weighs 0.45 kg. Use the handle if fitted and lift with your legs, not your back.
Do size and polarity both match my current battery?
Check two things together: size (90 × 34 × 65 mm) and orientation (positive on the left-hand side). Both must match.
How should I store the Fulbat FP4-3.5 if I don't fit it immediately?
Yes, gradually. Lead batteries lose a little charge each month, lithium much less. A quick charge before use is a good idea.
Dimensions and weight of this model?
Overall it is 90 × 34 × 65 mm (L × W × H) and tips the scales at 0.45 kg. Weight is a good clue to how much active material is inside.
