    Emergency lamp won't stay on

    I got a used emergency fluorescent lamp for a good price, or so I thought.
    It is MAJOR TECH REL360
    6v lead acid battery.
    It charges (as in red charge led lights up)
    But the lamps(1 or 2),only stay lit for a minute.
    I swopped the battery with a known good one, with the same result.
    I hooked a battery charger to the battery wires, and the lamps STAY lit, so that must be a definate clue.
    I thought capacitor, as it stores electricity.
    I removed the little circuit board, and don't see swollen caps, and nothing burnt, so unless you good folk can offer a solution, it is destined for the dustbin,as I don't have the electrical knowledge to fix, however, I can hold a soldering iron, lol.

    Measuring, we have 6v when off.
    when lamps are on, then the battery stops to 4.5v
    Both batteries have this behaviour.

    I can't take it back, as I damaged the body when dismantling.
