Introduction
Batteries are used to supply power to different devices, like mobiles, laptops, and car engines. Varieties of batteries are available in the market, depending on the materials used in them. Alkaline batteries are the primary batteries that use alkaline compounds as electrolytes, preferably potassium hydroxide (KOH). Electrodes can be zinc-carbon or other active chemicals that can react well in this alkaline electrolyte. Alkaline batteries are now highly preferred as their shelf-life is much longer than other batteries. The alkaline batteries are of two varieties, namely rechargeable and non-rechargeable batteries.
How to recharge non rechargeable alkaline batteries?
Despite its name, non-rechargeable alkaline batteries can also be recharged when completely out of charge. But it is essential to buy the most suitable charger that fits into that alkaline battery. Usually, rechargeable alkaline batteries lose their capacity with each recharge.
Non-rechargeable alkaline batteries need specially designed chargers, which are quite different from NiMH chargers used for charging other kinds of batteries. This kind of charger can recharge alkaline batteries 10 – 30 times. The manual provided with the charger should be consulted to know all the required details about the proper use of the device.
Several dead alkaline batteries are taken for the recharging process. But these batteries should not be leaking. First of all, it should be checked whether the batteries are still capable of recharging.
A battery tester is also needed that is easy to use and applicable for alkaline batteries of all sizes, including AA, AAA, 9V, C, and D. All the dead batteries in hand should be tested individually for leakage with this tester. Some batteries may be found as live and they do not need a recharge at all. A higher standard tester may be used for checking the voltage of the battery
A versatile battery charger is preferred for recharging dead alkaline batteries, which is capable of recharging all types of batteries. This type of charger is quite affordable and can be used for recharging alkaline batteries of all sizes. It can be used for recharging multiple alkaline batteries at a time.
The charger has an LCD display where it will show CHA, which means ‘Charging” when the battery is attached to the charger and switched on. It shows that the battery can be recharged. If it is written BAD on the LCD screen, it means the battery is damaged and cannot be recharged.
There are three indicator lights on the battery charger. The green light is on when a battery is fully recharged. The fixed red light is on as long as the battery is undergoing the recharge process. If the indicator light flashes red, it means the battery cannot be recharged. Each charging slot has an individual set of indicator lights, which will glow as per the condition of the battery plugged into that slot.
Normally, an AA battery takes 5 hours to be recharged while an AAA battery needs only two and half hours for being fully recharged. A C battery and D battery need 6 hours and 10 hours respectively.
When the recharging process is complete and the green light of the charger is on, the charger turns to trickle charge mode. Though the recharging process stops, the charger continues to supply power to the battery till it is unplugged and removed from the charger.
What happens if you charge non rechargeable batteries?
A non-rechargeable battery can be heated up easily while recharging, mainly when the recharging process is over. However, any leakage in the battery can cause an explosion if the seals on both sides are not intact. The electrolyte of the battery will be sprayed out when the battery leaks or explodes. A toxic gas is also released in this case, which can be harmful to human health. Moreover, the battery charger is also likely to be damaged due to such an explosion. So, it is best to be very careful while handling the recharging process of non-rechargeable batteries. Only a high-quality charger and tester should be used for recharging non-rechargeable alkaline batteries.
How to recharge batteries without a charger?
If no suitable charger is available for recharging a regular or non-rechargeable battery, one can follow some simple steps for recharging without a charger. Also, it may be difficult to carry a charger all the time and an old battery can be fully discharged at any instant, making the concerned device unusable.
The dead battery is removed from the device if it is accessible as per the manufacturing design of that device. Only the Apple products cannot be recharged in this process, as the batteries are inbuilt there and cannot be taken out.
Then some common household batteries should be taken, which are well charged. Any AA, AAA, or 9V battery can be chosen for this purpose. The power is the same in all kinds of batteries. But the voltage and amperage of the entire circuit should be correct so that batteries are not damaged in this process.
The positive and negative points of the chosen battery should be checked before proceeding with this recharging process. Usually, the connector nearest to the edge of a battery has a positive charge while the connector on the opposite end away from the edge should be the negative one.
The voltage of the battery to be recharged and the power supplier battery should be the matching to meet the requirement. The voltage of a common battery of a mobile phone should be more than 3.7V DC for being recharged with another battery. Hence, more than one AA, AAA, or 9V batteries are needed to recharge such batteries.
Two short pieces of metal wires are needed to join the batteries. All the batteries are connected in a series. Then, the negative point of the rechargeable battery will be joined to the negative point of this series. However, the batteries cannot be fully charged through this procedure of recharging without a charger.
Therefore, it is best to recharge an alkaline battery with the help of a perfect charger, to make it fully recharged for more use.
