I can recommend buying a so-called "battery-backed" powersupply for
atomics. They are built to be usedin fire-alarms, burglar-alarms
etc, and consist of a power-supply that understands how to charge
SLA's and a box. Mostly one has to buy the batteries separately.
They come in 12V and 24V versions.
Look for instance at RS-components 310-2058

Never attribute to malice what can adequately be explained by incompetence.
