NPP HR1224W 12V 6Ah Rechargeable Battery – 12Volt 144Watts 24Watt/ Cell High Rate AGM Sealed Lead Acid UPS Battery Replacement for NS1250, Alarm System Emergency Light, Flame Retardant F2 Terminal

Let me cut to the chase — if you’re looking for a 12V replacement battery for your UPS for this specific size, this NPP HR1224W is a solid pick.After researching through countless options, I landed on this one because it has decent reviews, the right size, and a much better price than the OEM options.1. It’s for UPS systems that need a 12V sealed lead acid battery that is 5.94 x 2.01 x 3.87 inches.2. It is the same size as the 12V 6Ah RT1250B battery used by some APC and SKE models.3. I’m currently using it in my APC BE600M1 600VA/330W UPS and it’s working great so far. It might have slightly less capacity than the original, but for the price difference, it’s a great trade-off.4. It also physically fits in the SKE VL425 425VA/240W UPS, though I haven’t needed to replace that battery yet.Bottom line: if your UPS needs a 12V 6Ah replacement with dimensions 5.94 x 2.01 x 3.87 inches. This one was a perfect fit for mine. Highly recommend!

Perfect low cost solution to get my APC BGE70 back in service

Some other products which purport to be replacements for the RT1255H are in fact slightly larger in at least 1 dimension. This is an exact match. It arrived quickly and was fully charged. It was simple to install and worked 1st time.

Works well.

It costs more to ship this back than what you pay.

Fit my pressure washer

Met all "as Advertised Form/Fit/Function " & my expectations except for delivery time .. I thought shippingwas covered under Prime but the seller used USPS.. ...longer wait than expected..

This is one of only a hand full of batteries that will fit a razor E90 scooter. Works greats. All the 12v 7 ah are to wide to lay down in this scooter and fit. You have to use a 12v 6ah for the razor e90 scooter
