HOW TO CHOOSE BATTERY CHARGER - good battery charger, which one to buy

Summer, Odessa, you walk with your mouth open, barely managing to take cool pictures for Instagram. And then my batteries run out! And the moment is very difficult: the wife and mother-in-law have just finished sitting on the Twelfth Chair on Deribasovskaya. They are followed by fifty people who you cannot ask to wait a minute while I run off to get new batteries ...

In general, the women I love drilled my brain. Mother-in-law turned on sarcasm (his battery never runs out) and said that she was ready to give me money for "good batteries". You understand, I could not miss this opportunity to recoup - and pointed to the charger for the batteries and a set of reusable batteries.

Killed all the birds with one stone. But then I realized the main thing: I stopped spending money on batteries, which at current prices come out "gold". This is no longer savings, but a net profit!

What you need to know when buying rechargeable batteries

Now that I have experience using reusable "fingers", I will tell you how to choose them and what kind of charging should be for rechargeable batteries.

Disposable batteries and rechargeable batteries are very similar, so in order not to buy a regular Alcaline alkaline battery, look for the words “Rechargeable” on them.

There are nickel-metal hydride (Ni-MH) and lithium-ion (Li-ion) batteries. The latter are used in mobile phones, laptops, tablets, and less often in the "battery" format. Therefore, we will not consider them here.

Nickel metal hydride batteries:

  • withstand up to 1000 recharges,
  • they can be stored for a long time,
  • work at low temperatures,
  • resistant to short circuits,
  • recharge quickly.

Early Ni-MH models had a self-discharge problem during storage. The new generation of such batteries has a low self-discharge and is designated LSD (low self-discharge).

When choosing a battery charger, adhere to the principle of versatility. First, it must accept both AA (finger) and AAA (little finger) batteries. Secondly, a good battery charger should combine two charging modes - high and low current. In it, the batteries will charge faster than in a slow one, but more carefully than in a fast one, that is, in general, they will last longer.

How to use batteries correctly

The more power the device consumes, the higher the battery capacity should be. It is indicated on the case and is expressed in milliamperes per hour (mAh). For remote controls, up to 1000 mAh will be enough, for children's cars and powerful flashlights, over 2500 mAh will be required.

If you are not using the device for a long time, remove the batteries from the device and store them separately. Also, do not leave batteries in chargers. Thanks to this, they will last longer.

Ni-MH rechargeable batteries have another secret - the memory effect. If you charge an incompletely discharged battery, then with the next use it will discharge only up to the limit from which it began to charge. Therefore, do not recharge your batteries for future use, but bring them to a full discharge. Or buy a battery charger that can “discharge” them before charging.
