Batteries & Battery Packs

This page gathers batteries for everyday devices and for security and fire equipment: alkaline cells in sizes such as AA, AAA, C, D and 9V, GP zinc chloride and NiMH rechargeable cells, lithium, coin, button and hearing aid batteries, replacement packs for alarm panels, detectors and access control, and Yuasa sealed lead-acid standby batteries. It also carries the kit around the cells: battery leads and harnesses, chargers, power banks and battery testers.

Choosing Batteries & Battery Packs

Decide first whether the battery goes in an everyday device or in security equipment: household cells are chosen by size and chemistry, system batteries by the part number of the equipment they power.

Household cells

Alkaline cells from Duracell, Energizer and GP cover the everyday sizes, with bulk options such as the Energizer 656.930UK AA 24 pack and Duracell Procell Constant boxes of 10. GP Greencell zinc chloride cells such as the 656.053UK AAA suit low to medium drain devices like clocks and remote controls, and ReCyko+ NiMH cells such as the 656.855UK can be recharged hundreds of times. GP supplies the largest share of the batteries on this page.

Alarm, fire and access control batteries

Security batteries are usually made for one system, so work from the part number. Ajax internal batteries such as the 149035.375.WH give the Superior Hub G3 up to 16 hours of backup to Grade 2, and the 132037.349.NC is a 6.4V 36Ah LiFePO4 pack for the Hub BP Jeweller. JCI Visonic packs such as the 0-9912-L power PowerMax panels. Comelit PAC CR2 and CR123A lithium cells (PLCYLB02, PLHDLB02) serve PAC Access Central access control.

Standby lead-acid batteries

Yuasa sealed lead-acid VRLA batteries come in 12V sizes such as the NP2.1-12 (2.1Ah), NP12-12 (12Ah) and NP17-12I (17Ah), and the C-TEC BC286/2 links two 12V batteries into a 24V 7Ah pack.

Chargers, power banks and testers

The page also carries battery chargers, such as the Veracity VAD-CHGR spare charger for the VAD-PS PointSource battery PoE injector. The Mercury 421.770UK is an emergency USB power bank that runs on 4 AA batteries, and the Chord 421.779UK is a 10,000mAh power bank with two 9V outputs for effect pedals. The Mercury 600.095UK digital and 600.098UK analogue testers measure cells under load.

Frequently asked questions

What types of battery are there?

Batteries split into single-use primary cells and rechargeable types. Everyday primary cells include alkaline, zinc chloride and lithium, in sizes such as AA, AAA, C, D, 9V and coin cells. Rechargeables include NiMH cells for household devices and sealed lead-acid batteries for alarm and fire panel standby power. Some alarm equipment uses a dedicated lithium pack made for one system.

How do I find a compatible battery pack?

Start with the model or part number of the equipment the battery powers, then match the pack's voltage, capacity, chemistry and connector. Alarm hubs, keyfobs and detectors often take a battery made for that one system, so the maker's part number is the safest guide. For standby lead-acid batteries, check the case size and terminal type too, such as Faston tabs or screw terminals.

What is a battery?

A battery is a portable source of power that turns stored chemical energy into electricity when it is connected to a circuit. It is made of one or more cells, in which a positive and a negative electrode sit in an electrolyte. Some batteries are single-use and others can be recharged many times. The range here includes household cells, coin cells, alarm batteries, standby batteries and chargers.
