I got a pdf from GivEnergy (after doing a search) on how to disconnect the batteries, remove the cover and attach the leads to the correct positive and negative

Good. That's the right approach.

If the PSU (power supply unit) is only capable of delivering 5A, then your connecting leads need be no bigger than 0.75mm².
That's the size of flex used for a table lamp.

I tend to use spare pieces of (solid-core) household wire which I strip out of cable for a lighting circuit (1.5mm²) or power circuit (2.5mm²).
The "old" wiring is great because it gives me a red and a black. 🙂

Set the PSU to deliver an output of 50v to start with, and leave the Amps as high as they'll go.

If you want guidance on making the connection at the battery end, post a photo here so we can see what you're presented with.

The connections need to be 'firm' in order to allow maximum current to flow. Dodgy connections have greater resistance, which will show up on the PSUs ammeter as low-current.

did contact Premium GE last night and they did reply, saying this is a known issue with these batteries and only solution is to bring the voltage up - but only an electrician should do this.

That's not a legal requirement for apparatus which operates below 75v. It's designated ELV (Extra Low Voltage).

But they're right to urge caution.
You must take care not to cause a short circuit across the battery.


Save energy... recycle electrons!
