Specifications HR03
Before installing the product in an electrical device, it will not be out of place to find out about the characteristics of this power source. The main parameters of HR03 include:
| Parameter | Value |
|---|---|
| Basic designation | AAA |
| The form | Cylinder |
| View | Ni-mh |
| Capacity | 550-1500 mA / h |
| Voltage | 1.2 v |
| Analogs HR03 | Read more HERE |
| Height | 44.5 mm |
| Diameter | 10.5 mm |
| Weight | ~ 12 gr |
| Operating temperature range | from -20˚С to + 50˚С |
| Number of recharge cycles | up to 1000 |
In size, they completely coincide with the little batteries, only the latter have a voltage of 1.5 Volts.
Analogs and what can be replaced HR03
If necessary, the HR03 battery can be replaced with an analog or a battery of the same size, provided that the circuit of the electrical device is resistant to a slight increase in voltage. Complete “substitutes” for the original battery are:
- Saline R03 - 1.5 v.
- Alkaline LR03 - 1.5 v.
- Lithium FR03 - 1.5 v.
- Nickel Cadmium Batteries KR03 - 1.2 v.
- ZR03 nickel-zinc batteries - 1.65 v.
the first three with a voltage of 1.5 volts are ordinary batteries. All of these analogues are able to completely replace the original. Some products have a significantly larger number of charge cycles, and this feature always affects the retail value of the product up.
Battery Applications
The battery can be used in any portable devices of relatively high power, for example:
- Flash units.
- Digital camcorders.
- MP3 players.
- Kids toys.
The HR03 battery can also be used in small power devices, which include various remote controls, calculators and fire alarm elements.
Note! The packaging always shows where it is best to use a power source.
How to charge battery HR03
In order for the nickel-metal hydride battery to last as long as possible, each charging process must be carried out in accordance with the manufacturer's instructions. For the HR03 battery, it is important to observe the following rules when restoring electrical capacity:
- Do not use “fast charge" if the cell is discharged below 0.8 Volts.
- The battery should not heat up when charging above + 50 ° C.
- Do not charge the product at an ambient temperature below + 5 ° C.
- Connect the battery to the charger only with the correct polarity.
Unlike galvanic cells, battery performance can be restored hundreds of times, but the number of such recharges depends on the manufacturing technology of the product, as well as on the correct charging and operation of the cell.
Popular manufacturers and their features
You can buy a AAA battery in almost any specialized store. The HR03 element is most often found under the following brands:
Of good quality, you can buy HR03 batteries under the FinePower brand, which also have a relatively low cost with standard capacity and the number of recharge cycles.
What to look for when purchasing
When buying pinky batteries, you should first of all pay attention to the capacity of the product.The larger this parameter, the less often it will be necessary to charge the product, thereby significantly postponing the date of purchase of the item for replacement.
If the capacity is small, but the manufacturer gives a guarantee for a large number of charge / discharge cycles, then this is also a sign of the longevity of the purchased product.
If the device consumes a significant amount of electricity, then the most preferable option is to buy a battery with a large capacity and the number of recharge cycles of at least 1000. Despite the high cost of such products, their operation will be much cheaper, since it will be less necessary to charge.
The listed designations are always applied to the product packaging. The battery case marking may also contain basic information, including:
- Voltage.
- Capacity.
- The number of charge / discharge cycles.
- The name of the manufacturer.
Having picked up the most suitable element, you should make sure that the product has not been subjected to excessive physical exertion. If the battery is of perfect cylindrical shape and its size corresponds to the AAA type, then you can safely purchase the product and use it in various portable devices.
It is better to buy a new battery in specialized stores or on well-known online sites. On open shelves, products can be exposed to negative temperature effects, as well as high humidity, therefore, it is not recommended to purchase a battery of type HR03 on the market.
