Which is why generally you shouldn't buy the genuine battery replacements.Good to know, thanks.
Although when the UPS are on offer, it still closes the gap.
Feels a bit like printers, cheaper to buy a new one than refill it. Lol. But the e-waste really bugs me.
E.g. that £97.99 650VA APC BACK-UPS linked above
The genuine RBC110 battery is around £60
UPS Trader has them for £15.17!
