## Questions & Answers

**Q: what a confusing description and picture... ffs what are they selling!? a 1 set battery or a 2 set ?...  a bell box needs 2x packs of batteries...**
A: This is for 1 battery, this is a single battery not this twin pack kit with cable. Older models require 1 battery not 2.

**Q: Hi i could not understand. is it comes as like as on advert picture is it? package included;  two batteries wired together x2 and 2xstickers**
A: It is, two 3.5 ah lithium batteries in a sealed unit for the outside security alarm. On mine there are 2 required. I would imagine the number required on your unit should have the connections inside. The batteries last 3/4  years as for the stickers, they are just advertising, if you want to add them to the outside of the alarm it's up to you.
