most UPS batteries is replaceable, but some don't accept 3rd party batteries

What’s the UPS brand ? They are most likely replaceable, pcandparts has battery replacement btw.

Mission Accomplished , 36000 LBP two batteries , and I replaced them my self ; better than paying 140 usd for a good 1200 VA UPS as this UPS

Hi there. Do you have information regarding choosing the correct battery? I asked around and was told all are 12V batteries but some are 7Ah and some 9Ah.

My question is if i have a 1200VA (2battery) or 1500VA (2battery of course) broken UPS, do i get the same batteries for both UPSs?
Also where did you get your batteries from? Macrocity has the PCE12V 7Ah battery for 16.7$ and PCE9Ah for 26.6$ including VAT.

Re: Are the UPS Batteries Replaceable

Same sort of question here,
My ups consists of 4 batteries of 7A.
Thing is u already own 2 new 9A ones, and I don't want to buy 4 new 7A ones.
So is it safe if I buy 2 new 9A ones and replace the batteries of the ups with 4 9As?

As long as the voltage rating is the same, and the current rating is the same (you either hook all 7 Ah or all 9Ah batteries, don't ever mix them when placed in series), it's ok to use either batteries. But there will be compromises and trade-offs in specific cases:

- when using a set of 12VDC 7Ah batteries to replace 12VDC 9Ah, you lose 2Ah: your UPS loses the capacity to provide appropriate current within 1 hour (2A to be specific). This move is not recommended mostly since your setup will mostly be needing that 9A/hr.

- when using a set of 12VDC 9Ah batteries to replace 12VDC 7Ah, you gain 2Ah but charging time for the batteries increases by at least 30min. This is an ok tradeoff for most UPSes, but some don't allow you to change the nominal voltage and current ratings for the batteries and will sound off an alarm for that. so best consult a user manual for that before buying and installing them.

check my answer above for more details, but getting 2 extra 12VDC 9Ah batteries should be fine as long as you are 100% sure your other batteries as still good (storing batteries while being fully charged decreases the life cycle of the batteries, hope you depleted or at least discharged half of it's current capacity before placing them aside; humidity also shortens the shelf life of batteries).

Pro tip: pay attention to the brand of the batteries before you buy them. E.K.T has HW and BigBat, both ok brands but require change every 3 years. The best on the market are the original Yuasa batteries (best life cycle amongst all), but generally require change after 7 to 10 years of consumption (depending on regular use). They are also the most expensive on the market. Is it worth the price tag? Absolutely.

It depends also on UPS. If you have crappy UPS that dont have 3-stage decent charger, you will flush your money in the toilet buying yuasa batteries for it.
