How long a battery can last?

The service design life of a battery are vary considerably with how it is used, how it is maintained and charged, temperature, and other factors.

Are lead acid batteries recyclable?

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.

What is battery cycle life?

One cycle of a battery is a discharge from full charge to full discharge and a return to full charge again. The total number of cycles a battery can perform before failure is called its Cycle Life. Moat battery manufacturers will not discus the Cycle Life of their product. Many advertised Deep Cycle batteries have not been tested, or, which is the case with cranking batteries, were never designed for long Cycle Life .


Storage Battery  is a kind of chemical energy directly into electrical energy device, is designed according to the rechargeable Battery, it recharge by reversible

chemical reactions, usually is refers to the lead-acid Battery, it is one of the Battery, belongs to the secondary Battery.How it works: when charging use external

power to make the internal active substances, to store the electric energy to chemical energy, need discharge to convert chemical energy to electrical energy output,

such as mobile phone battery is commonly used in life.Accurate charging method can maintain the life of the battery, there are some in the process of charging charging

error such as: early charge, to supplement the charging, battery charging, charging polarity reverse filling, etc.Right electric device charging method was that the

positive battery anode, battery cathode to connect power cathode;Then initial charge in two stages: first with the initial charging current into the electrolyte to

emit bubbles, the single voltage up to 2.3 ~ 2.4 V.Then reduced to 1/2 at the beginning of charging current, continue to electrolyte filling out severe bubbles, stable

voltage for 3 h.All the charging time is about 45 ~ 65 h;Should be used in the process of charging the electrolyte temperature measured in current by half, stop

charging or cooling method, the temperature control in 35 ~ 40 ℃, when the initial charge, if the proportion of the electrolyte illegal, application of distilled

water or electrolyte specific gravity of 1.4.Adjust the recharging after 2 h, until density conform to the rules.
