EnerSys NP7-12T 12V 7Ah F2 Sealed Lead Acid Battery

I needed a replacement back-up battery for our home security system. I received quotes from our monitoring company of $65 for the battery and $75 for the service call. A friend told me check on Amazon as they have just about any battery ever made available and you can watch a U-Tube video to show you how to change out your existing battery safely. Long story short, I went to Amazon and put in the name of the existing battery I needed to replace and sure enough they had one for $24.75 with free shipping. Took about a week to receive the battery because of some availability issues. I watched a 2 minute U-Tube video to safely install and sure enough our security system is working perfectly with the new back up battery. All for about $25 instead of paying about $140 from our monitoring company to replace. Great value, great service. Thank you Amazon.

This is a backup battery for many home security systems. I didn't realize my old battery was bad until a recent power failure, followed a couple of hours later by a shutdown of the security system (triggering a call from the security company). The old battery was about 10 years old, and I probably should have replaced it sooner as PM.This battery arrived quickly and serves the purpose. It is absolutely identical to the old battery. Installation is simple, and the savings for doing it yourself instead of a service call will pay for a very nice dinner to two.

Batteries work just great but we were replacing old ones in my stairlift. Ordered the exact same size, brand, numbers on the side matched what we had exactly. Got the batteries and the terminals were larger than what we had. Fortunately my husband was able to wire appropriate sized connectors to the stairlift wires and hook them up. But not everyone is so handy.

When I worked for an alarm company we use to try all kinds of brands of batteries. Many brands were garbage and as a serviceman I was able to tell how cheap it was by the lead weight in them.Commercial accounts, under maintenance agreements, always got the best equipment. If we had to go back yearly we were wasting money on replacement equipment and in paying employees wages for free service calls. Yuasa was our number 1 brand. It tends to cost more than the other brands but the life expectancy was the longest. Residential customers got whatever was the flavor of the month per the company. They paid us for the service call and for the battery on a 100-150% markup. Most generic batteries would last 1-3 years whereas some of our Yuasa's were going strong at 5 years.As with most alarm batteries, if your power is out for an extended period of time, be sure to unplug the battery before it dies completely. If you drain it dead it won't recover - the cells will be permanently damaged. Leave the alarm box wide open so you remember to plug the battery back in when the power returns though.PROS:- longevity if not cooked by charging circuit- quality lead acid- not likely to leak or swell up unless cooked by charging circuitCONS:- tend to cost more than other brands

There w2ere a lot of batteries priced 10-15% lower, but my experience with price-leaders hasn't been great. I have many of the 12v sealed lead-acid in various power backup units and I've learned the cheaper the battery the more often it's replaced. And replacement is a pain in a UPS, since it means the UPS is either beeping 24 hours a day or it's failed altogether.This battery was purchased for my smallest APC UPS, which loads the battery through a hinged door in the bottom. The original battery lasted several years and really didn't owe me a thing when it died. I wanted to have the same experience the second time, so I researched brands and YUASA is a very well-known and respected brand.Delivery was very quick, the next day after I ordered, and the fit and finish is smooth and solid. Installation was very quick, although one of the electrodes lays pretty parallel to the case and that made lead attachment a small challenge. The UPS was back in service in under five minutes and the battery seemed to be fully charged. I topped it off anyway before applying the load.I do feel this is worth the 10-15% up-charge over the bargain units, and I'm hopeful I'll get 5-6 years out of it.Another point to make is the old battery is recycled through many local sites, including the Radio Shack stores and the local office supply chains, so you don't need to keep aq stack in the garage or toss these in the dump. Just take them down the street and they'll be made into a new battery.

Work perfectly to replace my backup battery for my PC.

It’s straight forward

I only ordered from here because it said Yuasa brand. I received the product in few days but it was different brand. I kept them becaused I needed for my gate to function but still upset its not the ones I ordered. The battery is working fine so far but Yuasa lasted for about 6 years and another imitation only lasted 2 years. I will find out how long this one lasts. Sellers need to make it clear if they are selling different brand and not put pictures of brands that they are not selling!!!!!!!!!!!
