Our best advice is to charge the system without any load until fully charged, if you have the opportunity, which helps it reset to a new energy level properly.

Fitted in a Compaq 242689-04 UPS, you could expect a battery life span of between 2 and 5 years. However, usage over time will determine this.

While it may well be capable of much more, it will shorten battery life, so it's a balancing act.

These batteries can be mounted on the side without any issues, no leaking, which means they can be used in tower or rack mountable situations, they are the recommended VRLA type and benefit from AGM technology they are not-hazardous so safe for use in critical environments.
