cqr used to have clear plastic & you could see them inside I use to find them inside cables upto 1m or so, I reckon they crawled in, & each time one crawled in behind the they;d move up more ? battery in sounder will last 2yrs or 20 yrs....

pizeo's vibrate, thrips / thunder bugs or whatever climb inside stuff & don;t vibrate no more...

When you completely down-power It remembers the codes zone settings ect in the NVM. But it wont keep the clock going while its down powered, that will default to watchdog

Pretty standard yep.

just snip them individually that way you will know what colour goes where when you put it back/replace it. No need to down power completely just be aware the alarm will tamper

It puts more load on the psu it pulls more current than the psu is designed to provide, and eventually burns out the charging circuit

Brown tape yes

And not cut the spares off ......

As above But battery can sometimes prematurely die , might be example in a loft where I seen them die quicker , or sometimes boiler room and so on Yes load test , try it But you might be running all wireless aswell?

Yuasa rate NP batteries as 5 year service life for use within alarm systems, other manufacturers maybe different. From experience you could get 10 years from a Yuasa one but it's best to swap before it's deteriorating.

Hi, The battery should be replaced every four years. This is the manufacturers expected lifetime guidelines. I have known batteries to continue to hold good life long after four years, but accredited installers have to follow the manufactures guidelines. The performance of the battery is effected by many things, the quality of the electricity more spikes and fluctuations will reduce the life of the battery. The quality of the charging system (HKC is generally good) power cuts discharging and charging the battery will reduce its life. The size of the battery should reflect the current pulled from the system.
