How to extend the life of your bite alarms

1 "Always use alkaline batteries such as Duracell," suggests Gary Peet, co owner of The Tackle Box in Kent. "Not only do the cheaper alternatives have a shorter life, but the way in which the voltage changes as it gets older can cause problems with modern electronics."

2 "If you have the option, always keep a PP3 battery in an upright position as the damp always lays in the bottom of the casing of an alarm and that may cause corrosion and connectivity issues."

3 "Always dry out and air alarms after being wet. Also be aware that some covers designed to protect the alarms from knocks and bumps keep in damp. Although the waterproof coatings that are used on the circuit boards protect them in the short-term, extended periods exposed to water can be detrimental, it is a bit like being in the bath too long when your skin absorbs water. It's worth noting that Delkim offer a re-proofing service."

4 "Don't clean the plastic cases of alarms with WD40 as this can lead to the drying of the plastic and cracks can appear and in the worst cases the plastic can become porous. WD40 can also cause problems with the electronics."

5 "The positive battery post of a Duracell PP3 is thicker at the top than other PP3 batteries and this can sometimes cause problems when the battery is changed, the connector from the alarm can stretch and cause a loose connection. Although it feels a good fit due to the feel of connection on to the negative post."

6 "Always remove batteries if storing for long periods."
