What is the difference between 12a and 20a batteries?
2 Answers
Here is an introduction to the differences between 12a and 20a batteries: 1. Battery capacity: The 20Ah battery has 8Ah more capacity than the 12Ah battery; a 12Ah battery can discharge for 6 hours, while a 20Ah battery can discharge for 10 hours, providing 4 more hours of discharge. 2. Charger: A 20A charger for electric vehicles cannot charge a 12A battery because the 12Ah battery has a smaller capacity; normally, using a 12Ah charger to charge a 20Ah battery once in a while can extend the battery's lifespan. 3. Price: The 20Ah battery is more expensive, while the 12Ah battery is relatively cheaper.
The difference between 12a and 20a batteries, I've driven for over a decade and deeply experienced it. 12a usually refers to a 12 amp-hour capacity, which is more compact and lightweight, suitable for motorcycles, electric bikes, or small generators. It's cheaper but stores less power and discharges quickly. If used in vehicles with high demands, it might struggle to start or stall in cold winters. As for 20a, it has a significantly larger capacity, storing about 40% more power, with stronger endurance. It's more stable when used in small cars or equipment with large audio systems, less likely to fail. It's also heavier, so be sure to secure it properly in the trunk. The actual choice depends on the vehicle model. Small cars with 12a save money and hassle, but for long trips or cold regions, 20a is more reliable. The size may also vary greatly, so measure the space before installation to avoid getting stuck.
