The 4/400LAHT-B-AMP is a 4.8V 4000mAh Ni-MH (Nickel Metal Hydride) battery pack featuring a 250mm lead with AMP connector. It is specifically designed and cross-referenced for use in emergency lighting systems and other high-durability industrial applications.

Our batteries and battery packs are NOT to be used in any lighting fitting used in inflammable or hazardous areas. Hazardous areas are explosive atmospheres created by gases, vapours and ignitable dusts or fibres. These can be present in installations such as processing refineries, chemical production facilities, oil/gas platforms, flammable liquids storage facilities, fuel transportation, petrol stations, paint production, paper production etc. It is the customers responsibility to check on the environment that the battery / battery-pack is to be used in.

The 4/400LAHT-B-AMP emergency lighting battery is a NiMH stick design battery specially designed to handle industrial high temperatures plus is RoHS certified.

The rechargeable batteries are used when there is a mains failure providing light enabling safe evacuation.

NIMH Batteries

NiMH (nickel-metal hydride) batteries are rechargeable power sources that use a hydrogen-absorbing alloy at the negative terminal and nickel oxide hydroxide at the positive terminal.

They offer higher energy density than older NiCd batteries and are more environmentally friendly, but they have a higher self-discharge rate than newer technologies like lithium-ion. NiMH batteries are commonly used in household electronics, cordless phones, and some hybrid vehicles.

How they work

During a discharge cycle, the negative electrode (metal hydride) releases stored hydrogen, and the positive electrode (nickel oxyhydroxide) absorbs hydroxide ions, generating electricity.

During a charge cycle, the process is reversed, with electrons flowing from the charger to the positive electrode and then to the negative electrode, storing energy.

Advantages

Higher capacity: Typically have two to three times the capacity of NiCd batteries.

Environmentally friendly: Contain fewer toxic elements than NiCd batteries, making them safer to dispose of and recycle.

Less prone to memory effect: Less sensitive to the memory effect than NiCd batteries.

Good performance: Can operate well at a wide range of temperatures and are efficient at high-rate discharges.

Disadvantages

Higher self-discharge: They lose their charge faster than some other battery types when not in use, though low self-discharge (LSD) versions are available.

Shorter lifespan: Generally have a shorter cycle life and lifespan compared to modern alternatives like lithium-ion batteries.

Susceptible to heat: High temperatures can degrade their performance and reduce their service life.

Lower energy density: Have lower energy density than lithium-ion batteries, limiting their use in high-performance or very compact devices.

Common Uses

Consumer Electronics: Remote controls, digital cameras, toys.
Tools: Cordless devices.
Automotive: Older hybrid electric vehicles.
Robotics & IT: Industrial applications.
