We currently support a fleet of these defibs within the Trust, and had risk assessed,increased our test/replacement frequency, and use the Panasonic mainstream pack from Euro energy.
Our fleet is little more than 3 years old

We have just been advised that Panasonic (who manufacture packs both under licence to Philips, and to the wider market), are ceasing manufacure of this type.
Euro energy have dropped this pack from their catalogue as a result, and we can find no other battery manufacturer producing this pack. Yet Philips say they will continue to supply as necessary (at a cost/cell of £70+ as opposed to £28)?

This has significant implications for our maintenance programme, and so before we undertake a major transition;

Does anyone else on the forum support these defibs?
How do you deal with the question of battery management?

I would be grateful for your views/experiences

Best regards
