What is the best battery choice?

What is the best battery choice? What is the best battery choice? The

requirements differ between personal users and fleet operators. The

personal user can choose batteries in various sizes and chemistries.

Cost is a factor for many. If a smaller and less energy-dense battery

is chosen, a spare battery may be carried to assure continued

service. The energy requirements are quite different with fleet operators. The

equipment is matched with a battery designed to run for a specified number of

hours per shift. A degradation factor to compensate for battery aging is taken into

account. A reserve capacity is added to allow for unforeseen

activities. Allowing an aging degradation factor of 20 percent and

providing a reserve capacity of 20 percent will reduce the usable

battery capacity from 100 percent to 60 percent in a worst-case

scenario. Such a large percentage of reserve capacity may not always

be practical but the equipment manufacturers should consider these

safety factors when fitting the portable devices with a battery. The best choice is not necessarily an oversized battery, but one that has

sufficient safety margin and is well maintained. This is especially

true of NiCd batteries. When adding large safety margins, the reserve

capacity should be depleted once per month, if this is not done

already through normal use. more info:www.good-
