UPS Battery replacement

[x7razor]

Hi so i need to replace batteries on 2 x 850va's

Currently they have a Yuasa NPW45-12 installed. Where is the best place to buy replacements in CPT and what brand will be the best to buy or are they all more or less the same?

That is a 12 volt 4.5 amp/hour battery
RSEC in Bergvliet
This is not a very common size and all the available brands are much the same

Looks like it's actually a 7.5 amp/hour battery... ! (pretty deceptive, I know...)

So you should be able to replace it with any standard 7, 7.5, or 9Ah security-type battery as they are usually all the same dimension. The standard 7ah lead-acid variety is the cheapest. If you want good quality, go for a 9ah gel type

If you really want to go modern and future-proof, there are also lithium-ion drop-in replacements (eg: Blue Nova) available in this form factor, but they aren't cheap...
