Prostar GP7-12 best rechargeable lead acid battery 12v 7ah

Prostar GP7-12 best rechargeable lead acid battery 12v 7ah is only enough electrolyte in the mat to keep it wet, and if the battery is punctured the electrolyte will not flow out of the mats.

The storage battery or secondary battery is such a battery where electrical energy can be stored as chemical energy and this chemical energy is then converted to electrical energy as and when required. The conversion of electrical energy into chemical energy by applying external electrical source is known as charging of battery. Whereas conversion of chemical energy into electrical energy for supplying the external load is known as discharging of secondary battery.

Despite having a very low energy-to-weight ratio and a low energy-to-volume ratio, lead-acid batteries have an economically acceptable power-to-weight ratio. This feature, along with their low cost, makes the lead-acid batteries to be attractive for use in motor vehicles to provide the high current required by automobile starter motors and suitable for a number of stand-by applications.

Lead-acid batteries are composed of a Lead-dioxide cathode, a sponge metallic Lead anode and a Sulphuric acid solution electrolyte. This heavy metal element makes them toxic and improper disposal can be hazardous to the environment.

Features of Sealed Lead Acid Batteries

1. Sealed/Maintenance-free

The valve regulated spill proof construction allows trouble-free safe operation in any position. There is no need to add electrolyte, as gases generated during the charge phase are recombined in a unique “ oxygen cycle”.

Prostar sealed lead acid battery can be operated in virtually any orientation without the loss of capacity or electrolyte leakage. However, upside down operation is not recommended.

2. Long Shelf Life

A low self-discharge rate, up to approximately 3% per month, may allow storage of fully charged batteries for up to a year, depending on storage temperatures, before charging becomes critical. However, we strongly recommend that all batteries should be recharged within six months of receipt as it will enhance their long term life.

3. Design Flexibility

Same model batteries may be used in series and/or parallel to obtain choice of voltage and capacity. The same battery may be used in either cyclic or standby applications.

4. Deep Discharge Recovery

Special separators, advanced plate composition and a carefully balanced electrolyte system ensure that the battery has the ability to recover from excessively deep discharge.

5. Economical

The high watt-hour per dollar value is made possible by the materials used in a sealed lead-acid battery; they are readily available and low in cost.

6. Easy Handling

No special handling precautions or shipping containers, surface or air, are required due to the leak-proof construction.

7. Compact

Prostar batteries utilize state of the art design, high grade materials, and a carefully controlled plate-making process to provide excellent output per cell. The high energy density results in superior power/volume and power/weight ratios.

8. Low Pressure Valve Regulators

All batteries feature a series of low pressure one-way relief valves. These valves safely release any excessive accumulation of gas inside the battery and then reseal.

9. High Discharge Rate

Low internal resistance allows discharge currents of up to 10 times the rated capacity of the battery. Relatively small batteries may thus be specified in applications requiring high peak currents.

10. Rugged Construction

The high impact resistant battery case is made of nonconductive ABS plastic. The case materials impart great resistance to shock, vibration, chemicals and heat.
