Look­ing af­ter your bat­tery

Cycling Weekly - - Focus On Winter -

The most com­mon type of bat­tery in a mod­ern bike light is the lithium-ion (Li-ion) type. The beam strength or flash set­ting you se­lect will dic­tate how much run time you get from the bat­tery. Most lights will give you sev­eral hours on the low­est or flash­ing set­tings, but as soon as you move from lit streets to darker lanes, you’ll prob­a­bly need the bright­est set­ting, which can sig­nif­i­cantly re­duce the run time.

The life­span of a Li-ion bat­tery is be­tween 300-500 charge/dis­charge cy­cles. It’s ob­vi­ously im­pos­si­ble to say how many years that equates to be­cause it de­pends how of­ten it’s used.

Li-ion bat­ter­ies do not have a charge ‘mem­ory’, as the older type of Ni­cad bat­ter­ies did, so it is not nec­es­sary to com­pletely dis­charge and charge them. Many man­u­fac­tur­ers rec­om­mend charg­ing lit­tle and of­ten, with the oc­ca­sional com­plete dis­charge so that the bat­tery’s power gauge can re­cal­i­brate.

Dur­ing the sum­mer, it’s best to store a Li-ion bat­tery in a cool place at about 40 per cent charge. Stor­ing it ‘flat’ will re­duce its ca­pac­ity.
