One of the commonly used batteries in microelectronic devices are tablet batteries. In devices that consume relatively little power, such as watches, the L736 batteries are widely used.

L736 Battery Specifications
These are durable galvanic current sources that use an alkaline (alkaline) electrolyte (usually sodium oxide), a zinc cathode (minus), and also an anode of manganese dioxide.
In disc batteries, nickel-plated metal electrodes are part of the housing. The anode is a large part of their cylindrical body, and the cathode is a contact area with a smaller diameter inside the battery case.
They have a round shape resembling a tablet and the following specifications:
- diameter: 7.9 mm;
- height: 3.6 mm;
- weight 0.5-0.64 grams
- capacity up to 45 mAh;
- voltage of 1.5 volts;
- low self-discharge;
- electrochemical formula of MnO2;
- long shelf life (5-10 years);
- working temperature from -18 to +55 degrees.

Power supplies with silver oxide (ZnAg2O electrochemical formula) have better parameters than alkaline products: a large capacity (35-45 mAh when the voltage drops to 1.2 volts), a slightly higher voltage (1.55 volts).
They can operate at temperatures from zero to +60 degrees and have a longer shelf life and use (up to 10 years) compared with alkaline sources. They have the same weight (about 0.57-0.62 grams) and the temperature mode of operation (from zero to +60 degrees), but they cost 2-2.5 times more expensive.
Battery Applications
L736 disk batteries are very often used in the following devices:
- clock;
- remote controls;
- calculators;
- Kids toys;
- calculators.
Can I charge the L736 battery
Any disposable power sources, unlike batteries, are not subject to charge recovery due to the almost complete irreversibility of the chemical reactions that occur in them.
You should not try to win a couple of days of additional work of used batteries, because as a result of trying to charge them, excess pressure accumulates, damage to the case and subsequent leakage of electrolyte from them.
Leaked electrolyte from the battery damages the contacts, the housing of the electronic device, and in some cases its electronic components, which ultimately leads to many times more expenses for repair and cleaning of equipment than the hypothetically saved cost of a new power source.
Popular manufacturers and their features
Various manufacturers produce identical-sized batteries that have their own marking. Their parameters differ due to the applied electrochemical formula.
A great advantage of silver oxide cells is the lower likelihood of electrolyte leakage compared to low-cost alkaline cells, which is why it is better to use them in expensive watches.
The letters SW (analogue LD - low duty) and W (analogue HD - high duty) in the marking of batteries with silver oxide indicate reduced and increased power, respectively affecting their service life.
In the case of using similar active components, small changes in current sources may be associated with differences in manufacturing technology used by each company.
Guaranteed high quality products are available from manufacturers such as Energizer (Eveready), Duracell, Rayovac, Maxell, SONY, Varta, Konnoc, Philips, Mallory, Omega, Camelion, Panasonic, GP, Renata, Seiko, Citizen.
Cheaper products with appropriate quality are produced by manufacturers under the Cosmos and Our Strength brands (alkaline batteries G3 and AG3)
What to look for when purchasing
The purchase of power supplies from reliable manufacturers can significantly increase the life of electronic devices. When choosing them, you need to pay attention to details that will help protect yourself from fakes and from products spoiled by improper storage.
When buying a battery, you need to pay attention to such features:
- packaging integrity;
- compliance with the storage period;
- lack of streaks, oxides and deformation;
- high-quality printing on the packaging and clear markings on the battery case.
