AI Customer ServiceThe lead acid battery works well at cold temperatures and is superior to lithium-ion when operating in sub-zero conditions. Lead acid batteries can be divided into two main classes: vented lead acid batteries (spillable) and valve regulated lead acid (VRLA) batteries (sealed or non-spillable). 2. Vented Lead Acid Batteries
The nominal capacity of sealed lead acid battery is calculated according to JIS C8702-1 Standard with using 20-hour discharge rate. For example, the capacity of WP5-12 battery is 5Ah, which means that when the battery is discharged with C20 rate, i.e., 0.25 amperes, the discharge time will be 20 hours.
Various capacity parameters of lead-acid batteries are: energy density is 60-75 Wh/l, specific energy is 30-40 Wh/Kg, charge/discharge efficiency is 50-92%, specific power is 180 W/kg, self discharge rate is 3-20%/month, cycle durability is 500-800 cycles and nominal cell voltage is 2.105 V . [...]
3. Valve Regulated Lead Acid Batteries (VRLA) Valve regulated lead acid (VRLA) batteries, also known as “sealed lead acid (SLA)”, “gel cell”, or “maintenance free” batteries, are low maintenance rechargeable sealed lead acid batteries. They limit inflow and outflow of gas to the cell, thus the term “valve regulated”.
Stored lead acid batteries create no heat. High ambient temperatures will shorten the storage life of all lead acid batteries. Vented lead acid batteries would normally be stored with shipping (protecting) plugs installed, in which case they release no gas.
2. Vented Lead Acid Batteries Vented lead acid batteries are commonly called “flooded”, “spillable” or “wet cell” batteries because of their conspicuous use of liquid electrolyte (Figure 2). These batteries have a negative and a positive terminal on their top or sides along with vent caps on their top.
