Frequently Asked Questions

You may purchase Tesla Power USA Battery from any authorized dealer near you. Also, you may locate and visit the nearest available Tesla Power Shop to buy the products offline.
Overheating can reduce the lifespan of a battery. Excessive temperature boosts the rate of fluid loss which results in the internal damage of the battery and reduces its charge.
A battery is created by alternating two different metals such as Lead Dioxide (PbO2), the positive plates, and Sponge lead (Pb), the negative plates. Then the plates are immersed in diluted sulfuric acid (H2SO4), the electrolyte. The types of metals and the electrolyte used will determine the output of a cell. A typical fully charged lead acid battery produces approximately above 2.1 volts per cell. The action of the lead acid storage battery is determined by chemicals used, state-of-charge, temperature, porosity, diffusion, and load.
When the active material in the plates can no longer sustain a discharge current, a battery "dies / ages". Normally a battery dies as the active positive plate material sheds (or flakes off) due to the normal expansion and contraction that occurs during the discharge and charge cycles. This causes a loss of plate capacity and brown sediment called sludge or "mud," that builds up in the bottom of the case can short the plates of a cell out. This will kill the battery as soon as the short occurs. In hot climates additional causes of failure are positive grid growth, positive grid metal corrosion, negative grid shrinkage, buckling of plates or loss of water. Deep discharge, heat, vibration, fast charging and over charging all accelerate the "aging" process. Approximately 50% of premature battery failures are caused by the loss of water due to the lack of maintenance, evaporation from high under hood heat or over charging. Positive grid growth and undercharging causing sulfation also cause premature failures."
20 Hour capacity in the battery industry means what amount of amps can the battery deliver at a constant rate at 80 F before getting discharged.
A Pro-rata warranty refers to a partial warranty used for non-repairable products. Under this scheme, if a product fails before the end of the warranty period, the manufacturer replaces it at a cost that depends on the age of the item at the time of the complaint. This type of warranty covers only a part of the initial cost. However, the replaced product is then covered by an equal new warranty. If your battery fails in the pro-rata warranty cycle, then depending on the value of the storm, you will get a discount on the current price of the newly replaced battery. The pro-rata warranty is counted from the date of purchase to the date of complaint. For example, if a battery has 12+12 (free of cost + pro-rata) months of warranty and it fails in the 18th month, then 75% (as 75% of its duty cycle is over) value of the battery will be deducted from its current price at that point of time. You will get a 25% discount on the MRP of the newly replaced battery.
Yes, Lead acid batteries are 100% recyclable. Lead is the most recycled metal in the world today. The plastic containers and covers of old batteries are neutralized, reground and used in the manufacture of new battery cases. The electrolyte can be processed for recycled waste water uses. In some cases, the electrolyte is cleaned and reprocessed and sold as battery grade electrolyte. In other instances, the sulfate content is removed as Ammonia Sulfate and used in fertilizers. The separators are often used as a fuel source for the recycling process.
A rating that is used in the battery industry to define its ability to start an engine in low temperatures. The number of amps that a 12-volt battery will deliver for 30 sec at 0°F while maintaining a voltage of at least 7.2 volts. The higher the CCA rankings, the higher its starting power will be.
A dry-charged battery can be assumed a backup battery as it can be stored for a long period of time without any fear of getting damaged or corrosion. The dry-charged batteries do not have electrolytes installed in them.
