At a glance: Built for UPS and standby systems, the Long MSK440 carries the rating 440Ah 2V. Terminal position is the detail people most often forget.
Electricians often order the Long MSK440 during routine maintenance visits. Sealed construction lets it sit in a cabinet for years. Batteries online for alarms and UPS are filed by maker and code.
With 440Ah, it outlasts most batteries for UPS and standby systems on a single charge. With 29.7 kg on the scales, it weighs less than many batteries of similar capacity.
An alarm panel beeping at three in the morning usually means its battery is low. Recycle old batteries through an authorised scheme. Batteries that look perfect from outside can still fail under load.
Valve-regulated construction keeps an AGM case closed during normal life. Backup systems rely on AGM because it can wait, fully charged, for years without fuss. Replace an AGM battery whose case has bulged.
It is a good idea. All batteries lose some charge on the shelf, so a top-up before fitting helps.
At 197 × 170 × 342.5 mm and 29.7 kg, it needs a tray of that size and a careful lift.
