SLA may refer to any of the following:
1. Short for Service-level agreement, SLA is the measurable level of service a company guarantees to offer the user. Many ISPs and web hosts provide their customers with an SLA that outlines the measurable expectations the user can expect. Below are examples of what may be included in an SLA.
- The percentage of uptime, e.g., 99.9% guaranteed uptime.
- The guaranteed response time from a help desk, e.g., a response time of 15 minutes or less.
- The overall expected performance or benchmark of a connection or product.
- The expected penalty or credit if the SLA is not met.
2. Sealed lead-acid, or SLA, is a type of rechargeable lead-acid battery developed in the 1970s. It is also called a valve-regulated lead-acid battery, or VRLA. It features a relatively low energy-to-weight and energy-to-volume ratios. However, it is capable of providing high surge currents, so its power-to-weight ratio is relatively high.
