      had to order online--none carried at store. Could not find this specific 4 volt battery anywhere. I would have preferred a different brand as the last Enersys only lasted 2 years. My previous batteries (original installation) lasted 10 years.

                      As an burglar and fire alarm technician, I recommend these batteries to my customers willing to change out the batteries for themselves. If I I have to make a service call to change it, I charge a little more than twice the cost of this battery (for parts, gas, etc.)

                      Please note that if you have a 12v 8Ah battery and you switch to a 12v 4Ah battery, the 4Ah battery will not provide back-up power for your equipment as long as an 8Ah can. This is especially important if you have a lot of powered devices on your alarm system (multiple keypads, motion detectors, glass-breakage detectors, smoke detectors, etc.)
