The convenience of having a quality cordless phone is indisputable. In addition to freedom from a cord, cordless phones grace us with a myriad of benefits, including a large coverage area, substantial range, expandable handsets, long-lasting and rechargeable batteries. These batteries vary from one cordless phone model to another and are designed to serve you for up to three years.
Even with proper maintenance practices, cordless phone batteries usually lose functionality once the charging cycles are depleted. Such an occurrence could be a deal-breaker, especially when it happens unexpectedly. Fortunately, these batteries often exhibit warning signs before they seize functioning. Therefore, it is crucial to know how to tell if cordless phone battery is bad so that you can prepare yourself beforehand.
Cordless phone batteries deteriorate gradually, especially after prolonged use. You can tell if your cordless phone’s battery is bad by looking out for specific signs such as rapid discharge. Failure of your phone’s battery to hold a charge for as long as it used to is among the major indications that the battery is defective.
Other common signs to look out for include bulging, overheating, and battery failure to power on or attain maximum charge even after charging for the required amount of time. Read on to know more about the signs of a bad cordless phone battery, which will help you establish whether a repair or a replacement is the way to go.
Signs of a Bad Phone Battery
After efficiently serving you for at least one year, your cordless phone may misbehave depending on the usage and maintenance practices. During such instances, most cordless phone users often purchase a new handset when all they could have done was repair the battery. Therefore, before you embark on replacing your handset, consider looking out for the following signs of a bad phone battery:
Battery bulging
You can confirm whether your phone’s battery is swollen by placing it on a flat surface such as a table and looking out for any wobbling. Whether subtle or prominent, you shouldn’t ignore the swelling as it could be hazardous.
Battery swelling is often a result of overcharging your phone or repeatedly using an incompatible charger. If your cordless phone battery is swollen, it is advisable to avoid using your phone in that state. Fortunately, the problem can be easily resolved by a phone technician.
Overheating
One of the most emphasized maintenance practices for cordless phone batteries is storing them in a cool, dry place. Exposing the battery to a very high temperature will most likely result in overheating. Excessive charging is also a probable cause. Overheating may cause malfunctioning and, in the long run, compromise the battery’s ability to hold charge efficiently.
Failure to hold a charge
Having to constantly recharge your phone’s battery within short intervals due to rapid discharge is a sign of a faulty battery. Some cordless phone models use nickel-cadmium (NiCad) batteries, which are prone to memory effects. Due to the memory effect, failure to completely use up your battery before recharging compromises its runtime since the battery becomes unconscious of the unused percentage.
Failure to attain maximum charge
If you have plugged the battery into the charger for a significant amount of time, but it still fails to attain a full charge, the battery is faulty. However, ensure you confirm whether the charging system is effective by testing the charger on a different handset before concluding that the problem lies in the battery.
When should I replace my cordless phone battery?
The lifespan of your cordless phone’s battery mainly depends on its total number of cycles. A cycle consists of complete battery depletion followed by a full recharge without any disruptions. Most cordless phones feature up to 1000 cycles, which can last for about twelve months. It is therefore advisable to replace your cordless phone’s battery after every twelve months.
Additionally, if your phone’s battery exhibits one or more of the signs mentioned above, it may be time to replace it.
How long do batteries last in cordless phones?
Rechargeable batteries in cordless phones are designed to last for up to three years. However, their longevity largely depends on whether or not you handle the battery with care. Proper maintenance practices such as storing the battery at room temperature can go a long way in extending your cordless phone’s battery life. However, the battery tends to rapidly lose its ability to hold a charge without these practices and may last for barely one year.
How to test cordless phone batteries
You can test cordless phone batteries using a multimeter by following the steps below:
- Charge the battery for the required amount of time as stated by the manufacturer.
- Subsequently, ensure you turn on your multimeter and set it to the direct current voltage setting, often labeled as DCV.
- Connect the multimeter’s red probe to the battery’s positive terminal.
- Similarly, attach the black probe to the negative terminal.
- Check the voltage reading on the multimeter. The reading should correspond to the battery’s total voltage (usually indicated on the battery) to indicate that the battery attained a full charge for a well functional battery.
FAQS
- What happens if you put normal batteries in a rechargeable phone?
Putting normal batteries in a rechargeable phone may come in handy during emergencies when the rechargeable batteries are depleted. However, note that not all rechargeable phone brands are compatible with normal batteries.
More importantly, even if your rechargeable phone is compatible, refrain from charging non-rechargeable batteries as this is hazardous. Non-rechargeable batteries feature an irreversible electrochemical reaction. Charging them may therefore cause overheating and leaking of harmful chemicals or, even worse, an explosion.
- Can you replace batteries in cordless phones?
Yes. If anything, you should replace cordless phone batteries at least once in three years, depending on usage. These batteries are made up of chemicals that generate many replenishable electrons. However, once the chemicals are depleted, you remain with a defective battery, and even recharging the battery may not renew the electrons. At this point, you should opt for quality and compatible replacement batteries.
- Does putting batteries in a freezer recharge them?
Putting batteries in a freezer barely recharges them. Rather than recharging, freezing the battery mainly slows down its discharging rate. Freezing, therefore, extends the battery’s runtime by enabling it to retain charge for a longer time than usual. However, you should ensure the battery reverts to room temperature before reusing it for safety purposes. Moreover, the action may have detrimental effects on your battery and should be done only during an emergency.
- Do rechargeable phone batteries wear out?
Yes, they do. The rate of wearing out, however, depends on how well you maintain the batteries. The battery can last for two or more years with proper maintenance; otherwise, the battery may begin malfunctioning in a year or less. Here are some effective maintenance tips to help extend your battery’s lifespan:
- Clean the battery terminals every once in a while, preferably using rubbing alcohol to prevent the accumulation of debris.
- Excercise the battery rather than leaving it idle for months.
- Cycle charge the battery at least once a month by discharging and recharging it fully.
Additionally, despite proper maintenance, the battery is bound to wear out eventually. Once the battery uses up all its cycles, it’s time to replace it so that your phone functions efficiently.
Conclusion
Having to replace your handset’s battery every once in a while may be a bitter pill to swallow, but it is necessary so that you can continue enjoying the convenience of your cordless phone. It would be best if to avoid waiting until your phone’s battery fails before contacting a technician or getting yourself a replacement. The functionality of cordless phone batteries declines gradually, giving you ample time to prepare yourself beforehand.
During this time, look out for warning signs such as battery swelling, overheating, and failure to hold or attain maximum charge. Consider reaching out to a technician once you notice any of these symptoms. Although inevitable, battery incapacitation can be slowed down by exercising the aforementioned maintenance practices.
