Hi Alan and others,
Alan, you suggested: "Naturally with these batteries you need to charge, then
flatten, charge,
flatten, charge, flatten and naturally, charge before going out into the field.
They also last
longer with full discharging and charging each time."
If the torch uses Ni-Cad or Nimh cells then your suggestion is reasonable. But
if the torch uses
lead-acid cells (the so-called motorcycle battery) the suggestion is not so
good. It is not really
advisable to continually fully discharge lead acid batteries.
Doing so will shorten their working life and can make them harder, if not impossible, to recharge
with standard battery chargers.
This goes for the liquid or gel type electrolyte batteries.
The lead acid type batteries are probably better for spotlight applications as
they hold their
charge better between outings. And they don't have to be fully discharged before recharging. In
other words, they can simply be topped up, something that the other types of rechargeable batteries
don't tolerate so well. Although the Nimh type are better than the Ni-cad type in this regard.
