On average most walkie talkie batteries will last around 18 to 24 months, depending on the quality of the battery, how you use your walkie talkie and charging cycle.
If you are wondering how long batteries will last until they need to be recharged, then it does depend a lot on how much you are using your walkie talkie,and which type of walkie talkie you have. However, the average walkie talkie would last around a day with normal use.
Most walkie talkie, if used moderately, will easily last an eight hour shift. If you need your walkie talkie to last should you have to work overtime, then you will need to consider different battery sizes and types.
The 5-5-90% cycle
There is spesific cycle in radio amature community. It’s called the 5-5-90% cycle time assumption. This basically means that when you use a walkie talkie, 5% of your time is spent transmitting, 5% receiving and 90% on standby. When you use a mobile phone and someone calls you, you are always talking and listening, whereas with a walkie talkie, on some occasions you may only be doing one of these things.
For examples, you might need to listen to instructions given by a team leader but not have to reply or respond to these instructions. Or you may just need to speak occasionally on your walkie talkie to give updates to your team as to what is going on, without needing a reply.
By using this system on a walkie talkie, and not always having to simultaneously talk and listen, you save battery. Mobile phone struggle to compete with walkie talkies when it comes to battery life. If a user goes over the 5-5-90 cycle time, then a walkie talkie with a higher capacity battery may be needed. Mobile phones only really have two states, in call or on standby (in use or not in use). However, walkie talkies have three states, in-use where it’s transmitting, receiving a call or on standby.
Looking after your batteries
There are many ways you can help your batteries to last longer. Only use your walkie talkie to communicate when necessary and storing your batteries in a cool, dry place. If you leave your batteries in a hot or very cold environment, it can significantly reduce their battery life. Overcharging your walkie talkie can also reduce battery life.
