How much spare capacity should a battery have?

The allowable capacity range is 80-100%; a spare capacity of 20 percent is recommended for critical use. Allow more capacity reserve when operating at cold temperature. To verify sufficient spare capacity in a battery fleet, identify batteries that are close to retirement and spot-check their capacities after a busy day with a battery analyzer.

How important is a battery's reserve capacity?

Often looked past or misunderstood, a battery’s reserve capacity is quite important to reliability. Batteries can have strong cranking health, but poor reserve capacity health. Reserve capacity refers to how many minutes the battery can deliver 25 amps at around 80F before it drops to 10.5 volts.

Do batteries have good cranking health?

Batteries can have strong cranking health, but poor reserve capacity health. Reserve capacity refers to how many minutes the battery can deliver 25 amps at around 80F before it drops to 10.5 volts. Poor reserve capacity can leave a driver without enough energy to restart their engine unexpectedly.

Do larger batteries have higher reserve capacity?

Battery Size and Weight: In general, larger batteries tend to possess higher reserve capacities. However, it’s important to strike a balance between the reserve capacity and the physical size and weight of the battery, as the application may have limitations in terms of space and portability.

How do I check a battery's spare capacity?

To verify sufficient spare capacity in a battery fleet, identify batteries that are close to retirement and spot-check their capacities after a busy day with a battery analyzer. The Cadex analyzer provides this function on the “Prime” program in that it applies a discharge before charge.

What should the battery voltage be?

If the temperature is 70°F (21°C) or higher, the battery voltage should be at or above 9.60V. If so, the battery can be returned to service. If below 9.60V, the battery should be rejected. This procedure should help determine whether the battery has sufficient cranking power and capacity.
