2. Battery charger - Wikipedia

   en.wikipedia.org/wiki/Battery_charger

   For example, for a battery with a capacity of 500 mAh, a discharge rate of 5000 mA (i.e., 5 A) corresponds to a C-rate of 10C, meaning that such a current can discharge 10 such batteries in one hour. Likewise, for the same battery a charge current of 250 mA corresponds to a C-rate of C/2, meaning that this current will increase the state of ...

3. Nickel–metal hydride battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–metal_hydride_battery

   Most manufacturers claim that overcharging is safe at very low currents, below 0.1 C (C/10) (where C is the current equivalent to the capacity of the battery divided by one hour). [23] The Panasonic NiMH charging manual warns that overcharging for long enough can damage a battery and suggests limiting the total charging time to 10–20 hours. [22]

4. List of battery sizes - Wikipedia

   en.wikipedia.org/wiki/List_of_battery_sizes

   This is a list of the sizes, shapes, and general characteristics of some common primary and secondary battery types in household, automotive and light industrial use. The complete nomenclature for a battery specifies size, chemistry, terminal arrangement, and special characteristics.

5. Nickel–iron battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–iron_battery

   The active materials are held in nickel-plated steel tubes or perforated pockets. It is a very robust battery which is tolerant of abuse, (overcharge, overdischarge, and short-circuiting) and can have very long life even if so treated. [7] It is often used in backup situations where it can be continuously charged and can last for more than 20 ...

6. Lithium polymer battery - Wikipedia

   en.wikipedia.org/wiki/Lithium_polymer_battery

   The battery used to start a vehicle engine is typically 12 V or 24 V, so a portable jump starter or battery booster uses three or six LiPo batteries in series (3S1P/6S1P) to start the vehicle in an emergency instead of the other jump-start methods. The price of a lead-acid jump starter is less but they are bigger and heavier than comparable ...

7. Lithium iron phosphate battery - Wikipedia

   en.wikipedia.org/wiki/Lithium_iron_phosphate_battery

   The specific energy of LFP batteries is lower than that of other common lithium-ion battery types such as nickel manganese cobalt (NMC) and nickel cobalt aluminum (NCA). As of 2024, the specific energy of CATL's LFP battery is currently 205 watt-hours per kilogram (Wh/kg) on the cell level. [13] BYD's LFP battery specific energy is 150 Wh/kg ...

8. California's piers may not be able to withstand climate change

   Climate change continues to worsen the coastal storms that batter California's aging piers. The result is frequent and expensive repairs.

9. Nickel–cadmium battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–cadmium_battery

   This results from repeated overcharging; the symptom is that the battery appears to be fully charged but discharges quickly after only a brief period of operation. In rare cases, much of the lost capacity can be recovered by a few deep-discharge cycles, a function often provided by automatic battery chargers.
