The battery is the most critical single element of an emergency power or lighting system.

It is also the most misunderstood and forgotten part of the system. They suffer from MISUSE and NEGLECT.

MISUSE - A battery used in emergency lighting, exit or UPS equipment must be capable of providing a measured amount of current for a sustained period of time.

Whereas, batteries used in automotive applications must provide a high current for a short period of time. (Cranking or starting power.)

Car batteries cannot, and must not, be used as replacements in UPS's and equipment used for emergency lighting equipment !

The NFPA Life Safety code 101, SECTION 5-9 - EMERGENCY LIGHTING,  states in part . . . .

  • "5-9.2.4 Battery operated emergency lights shall use only reliable types of rechargeable batteries provided with suitable facilities for maintaining them in properly charged condition. Batteries used in such lights or units shall be approved for their intended use and shall comply with NFPA 70, National Electrical Code."

NEGLECT - Battery, as well as system, maintenance is not only good practice but also in the case of emergency lighting equipment is a matter of LAW.

There is a great amount of information about batteries available from a variety of sources. Some of it is even true and may be applicable to your systems.

ELESCO got its start as a Master Distributor of batteries.

With over 45 years of continuous experience in servicing both batteries and emergency lighting equipment there is one thing that we have found to be universal.

  • General information can get you into trouble.
  • Specific information is what you need to get the maximum performance from battery operated emergency equipment.

Some of the generalities are:

  • Store batteries at a low temperature if possible - 5 deg C is ideal. Although capacity goes up with temperature, the life of a battery goes down.
  • The self discharge rate goes down with temperature. At room temperature, recharge stored batteries every 6 months; storage at 5 deg C lets you wait 18 months before recharging.
