Common Battery Terminology
Understanding battery terminology can be confusing, but it’s essential for making informed decisions. Terms like voltage, capacity, and CCA (Cold Cranking Amps) are commonly used. Voltage refers to the electrical potential difference, while capacity indicates how much charge a battery can hold. CCA measures the battery’s ability to start an engine in cold temperatures.
- Voltage : Electrical potential difference.
- Capacity : Amount of charge a battery can hold.
- CCA : Cold Cranking Amps, crucial for starting engines in cold weather.
Decoding LH and RH on Batteries
The terms LH (Left Hand) and RH (Right Hand) are used to describe the orientation of the battery terminals. LH means the positive terminal is on the left, while RH means it’s on the right. This distinction is vital for ensuring that the battery fits correctly and functions properly in your vehicle or equipment.
- LH (Left Hand) : Positive terminal on the left.
- RH (Right Hand) : Positive terminal on the right.
