Perfect battery for the alarm system display. Lasts for years.

Good battery, cleared the trouble on the alarm.

Fit perfectly on my Honeywell system. Swapped it directly out with the OEM battery. Wire was a perfect length as well. Installation time was probably 5 mins. No more beeping! Hallelujah.

works well, always think batteries are too expensive so only gets a 4. have no had long enough for longevity question. recharges well

Used this for my security control panel. It is a backup battery cause security system is hard wired with a back up battery in the control panel. Most IMPORTANT: the NEW battery will have to charge once you put it in the panel. So the security control panel message may still read low battery for awhile....just forget about it for about 3 hours and then your low battery message goes away! The wires from the battery were plenty long enough to reach the plug inside the panel. Evidently, you have to watch out for short wires on some of these batteries. I looked at the pictures of the different wires on the batteries and then decided. I have not measured the length of the wire so I can't help with that determination. So I highly recommend this product...has a long wire, charged up quick ONCE INSTALLED, Great Price.

Battery didn't last long

Direct replacement for my home alarm. On my alarm, you open the panel by depressing the two tabs on the top of the control box (it's hinged at the bottom and swings down), unplug the old battery, unscrew the plastic bar holding in the battery, and put in the new battery pack in the reverse order. Very easy. Now we don't get the "low battery" alert.

Excelente producto, las compre hace mas de un año y siguen funcionando como el primer día, solo asegurate de no dejarlas cargando mas de 3 horas

Es el remplazo adecuado para la bateria de mi alarma Honeywell, lynks, no puedo decir mucho sobre el desempeno por que aun tiene un par de semanas instalado, hay que esperar a ver si no se degradan muy rapido las baterias, las originales duraron cerca de 10 años. El conector es el correcto

Good quality packing. Works well with my alarm system. However I only need 1 pack but the minimum order is 2 packs.

I needed a new battery pack for my alarm system, and this worked perfectly. It is exactly as described, and was charged within just a few hours.

Works great. Exactly as described!

I tend to replace these about once per year. Not sure my panel actually recharges the batteries, so they die off if we lose power. Cheaper than a new alarm panel I guess !
