Power-Sonic PSH-1255F2 FR battery (12 volt, 6 amp, flame retardant)

This battery (my UPS needs two of them) works fine with my Belkin UPS. The leads seem to be properly attached, and the batteries are sized appropriately so they fit in the compartment.

Received the item as it was advertised, the item is performing as advertised on Amazon and was in perfect condition upon receipt.

Works Great

This is a good sealed, lead-acid battery. I've almost never had a Powersonic Battery fail pre-maturely. It is always a good idea to make sure they are fully charged before using them, as they could be only partially charged if they've been on the shelf for a few months or more. You can do that by connecting them to a smart charger or....a DC power supply set for 14.5 volts, with a maximum current of 1/20 C (C= battery capacity in ampere-hours) until the charging current falls to 1/100 C.

Purchased these to replace the batteries in my APC Smart UPS 2200. After searching around, I found these to be the best cells due to the fact of the higher amperage compared to the stock 5A cells. Now my UPS has gained around 5 minutes of run time at a 1200W load. I am very impressed, and will be buying more of these in the years to come if needed!

I used two of these to build a replacement pack for my Worx Lawn mower, WAY better than the cheap OEMs! No joke, last 30-50% longer, and had them almost a year and still going strong (for a repeated high discharge that is really good).Not only that, they deliver more AMPs to my little toy mower now keeps up with its gas powered ancestors and mulches no problem!

Nice heavy duty battery

Very Happy. Works great.
