Lithium vs Lead-Acid Golf Cart Batteries: A Comprehensive

With the improved power-to-weight ratio provided by lithium batteries, golf carts can reach higher top speeds compared to those powered by lead-acid batteries. Most lithium-powered golf carts can achieve speeds of up to 25-30 mph, depending on the model and the specific setup of the cart. This is a noticeable increase over the typical 20 mph limit seen in carts with lead-acid

Innovations of Lead-Acid Batteries

ingly low energy-to-volume ratio, lead-acid batteries have a high ability to supply large surge currents. In other words, they have a large power-to-weight ratio. Another serious demerit of lead-acid batteries is a rela-tively short life-time. The main reason for the deteriora-tion has been said to be the softening of the positive elec- trodes.

6 FAQs about [Inspection ratio of lead-acid batteries]

What is included in a battery inspection?

Quarterly inspections include same measurements as monthly inspection and in addition, voltage of each cell, specific gravity of 10% of the cells of the battery and float charging current, temperature of a representative sample of 10% or more of the battery cells.

What are the standards for battery testing?

There are a number of standards and company practices for battery testing. Usually they comprise inspections (observations, actions and measurements done under normal float condition) and capacity tests. Most well-known are the IEEE standards:

What are the standards for battery maintenance?

Most well-known are the IEEE standards: IEEE 450, “IEEE Recommended Practice for Maintenance, Testing and Replacement of Vented Lead-acid Batteries for Stationary Applications” describes the frequency and type of measurements that need to be taken to validate the condition of the battery.

Can internal ohmic readings be used as acceptance criteria for lead-acid batteries?

There were variations in the internal ohmic readings that were unrelated to the test variables. Based on the preliminary results of this study, it is recommended that internal ohmic readings not be used as the sole acceptance criteria for lead-acid batteries.

How do you test a lead-antimony battery?

In the case of a lead-antimony battery, measure and record the specific gravity of 10% of the cells and float charging current. For chemistries other than lead-antimony and where float current is not used to monitor the state of charge, measure and record the specific gravity 10% or more of the battery cells.
