Battery Analogs LR43
Problems with the purchase of the LR43 battery usually do not arise, but if you need to replace it with an analog, the following batteries will be most suitable for this purpose:
- G12;
- AG12;
- RW84;
- 1167A;
- V12GA;
- SR43W;
- GP86A;
- LR1142.
Depending on the analog and manufacturer, the capacitance and voltage may vary slightly. The larger the capacity, the longer the device will last. The voltage can differ by 0.05 volts, for most devices this error does not matter.
Can I charge the LR43 battery
Batteries of this type are not intended for recharging. Ignoring this rule can lead to a sad consequence. Even if it is possible to restore the battery for a short time by supplying constant electric power of small power to its contacts, the battery installed back into the electronic device may leak. As a result of electrolyte spills, the device may be completely damaged.
It is also possible that the battery is overheated during charging, which can cause an explosion or fire.
Popular manufacturers and their features
Better buy batteries made by trusted manufacturers. On sale you can find LR436 batteries manufactured under various brands, but the following brands are the most popular:
- Robiton
- Smartbuy
- Rexant
- Energizer
- Perfeo;
- Minamoto;
- GP;
- Camelion
- Vinnic;
- Space.
The products of all the listed manufacturers have a standard shape and voltage. Also, batteries practically do not differ in quality, but the cost of products can vary significantly depending on the fame of the manufacturer.
Information about the manufacturer can be read on plastic or paper packaging. Also, the logo or company name is applied to the positive contact of the battery.
What to look for when purchasing
The acquisition of counterfeit products can lead to disappointment, which will be much stronger than the joy of buying an inexpensive product. This does not mean that the store always needs to choose the most expensive battery.The price of products of famous brands always includes the cost of an advertising campaign, so in this case, wasting money can be from 50 to 100 percent. The main rule is not to purchase batteries at a price well below the average for this type of battery.
In the case when the battery was made strictly according to the technological rules, but it was not stored correctly or the shelf life of the product came to an end, the buyer will also receive a practically inoperative element. To protect yourself from such a purchase, you should carefully study the signs on the packaging or on the battery case. If the expiration date is about to end, then you should not purchase such a product. In the event that there are traces of abrasions or strong mechanical stress in the form of scratches and dents on the battery, the purchase should also be abandoned.
