UPS battery capacity in ah

[cavedog]

So I got a battery from the China shop because well it's cheap. R100 for a new battery made in Vietnam that fits in a UPS.

The problem is usually they are displayed in ah if I'm not mistaken such as 7.2ah or something like that but this battery is showing 12V 26W.

So what is the capacity of this battery compared to the 7.2ah battery?

Thanks

I = W / V

Therefore

? = 26/12
Current= 2.17A


i might of read wrong im on my phone in a rather bumpy car ride

Found the battery details. 12V 7.2aH/28W battery. R100 is not a bad price. Wonder where they get their batteries but they have like 40 of them at the China Shop where I bought them. Bought 3 of them.

Most likely 26w is a model number or indication of the power of solar panel to use to charge it. If it looks like an alarm/gate motor battery most likely it is around 7Ah. Have seen similar batteries in China malls with that capacity on the label.

Well do work great to be honest. Not sure how long they are going to last but they do work well for now.

What kind of load are you applying to it?

You get 9ah batteries with the same physical dimensions, cost a bit more. Got one in my UPS.

I was initially looking for those but could only find decent priced ones online. I have 1 old 600va ups that needed a battery and bought a new 1200va ups.

If I link them would it cause any damage?

I'm not looking to run on a ups as a backup I got a generator for that but feel the single ups for all these things pulls it empty fast especially if everything is on.

BS.

You running that on a 7ah battery?

Yes. I was not gaming just browsing the net so the gaming pc was not pulling too much power. The ps4 and tv was also just on not gaming on it and the battery lasted like 5min give or take from full power.

CSB is one of the best brands around for SLA batteries. There are fakes around however. That sounds a bit cheap for CSB
