Comparison of 4 batteries that work on acid and lead

Nickel-cadmium batteries are the most widespread and used among all rechargeable batteries, due to their light weight and can be manufactured in small sizes such as (AA) and even (AAA) that are used in finger-light batteries.
But the problem with these batteries is that they have memory meaning that if we recharge a battery
Nickel Cadmium has not been partially discharged several times, so we will remember the partial charge and never accept the full charge after that. However, the memory can be erased very often, by completely discharging and recharging three or four times.
Also, nickel-cadmium batteries lose their strength within two or three months when they are not in use
usage, and it should be recharged after each such period in order to keep it in good condition. If this is not achieved, nickel-cadmium batteries become vulnerable to the dilemmas of deep discharge of charge, which means that they lose charge and dry out extensively, which makes them not rechargeable again.

Acid/lead batteries:
Electronic flashes now provide another type of power source, which is a modern redesign of an old and reliable design, namely the lead-acid cell. These new lead cells use a sealed, rolled plate design.

These lead-acid batteries accept recharging as is the case with nickel-cadmium batteries, but unlike nickel-cadmium batteries, we find that they are strong and can withstand a lot of abuse, such as: fast charging and discharging rates, and overcharging without suffering from the dilemmas of leakage and discharge. Nickel-cadmium batteries suffer, and while they are stored, lead-acid batteries do not need to be recharged once a year.

Unlike the case with nickel-cadmium batteries as well, we find these sealed six-volt lead cells and are of the type that can be recharged at any time during their discharge cycle without memory effect.
The lead cells are external energy sources that provide between 100 and 200 full-energy light flashes per charge, with a return to standby period of six to seven seconds, and this is an ability that far exceeds that of nickel-cadmium batteries. As for automatic operation, the acid / lead cells will provide a much larger number of light flashes, the amount of which depends on the distance between the flash and the subject. The four models:
There are currently four 6-volt lead acid batteries designed to power most of the electronic flashes commonly used today: Quantum Battery I, Protech Elimina tor Professional, and Spiratone Super Gel Pack. And Simon Supercharger (Supercharger).
. All four are used in conjunction with a model that resembles a group of four AA batteries. The model group is inserted into the battery compartment of the flash. It is worth noting that the lead/acid battery attached to the waist or shoulder belt persists in providing a constant energy rate even before its charge is discharged by a few flashes of light.
This, and because of the wires that connect the modules to the battery packs, we find that the battery compartment doors on the flash drives will not close completely. Many flashes can be used without modification. However, there are some doors for the battery compartment that must be notched in order to accommodate the measuring unit and the wire.
The Quantum Battery I, is the only one of the four that features special modules for the unusual battery shapes found in flashers like Olympus and Minolta Maxum. Only two units, the “Battery A” and the “Supergel Pack”, have two power transmission ports that operate two flashes simultaneously. The Spiraton also has automatic windings for Nikon, Minolta and Canon cameras. Energy can be supplied to it with its Super Gel Pack at the same time while it secures power to flash. And when securing energy for two flashes, the two regain their readiness to work at the same rate as one flash, all that is required is that we have to explain the total number of available light flashes by half.
It also has two power outlets, but: each provides a different re-readiness rate. The normal port restores readiness in less than twice the time required for the standby port of either «Simon Supercharger Super. Then to use the super port with a standard L wire, we can get an adapter from the shop we deal with.
f- For battery I, an on/off switch to save battery power. As for the “supercharger”, it uses the on / off switch in the flash to cut off the power. As for the supergel pack
and “The Eliminator,” so they cut off their energy by removing the plug from the battery, and an internal start/stop switch appears.
This and the “I battery” are packed in a leather box to provide a good look and to protect them from shocks, while the other three are packed in hard plastic boxes.
And the four batteries use a group (LED) on their pages (LED). This also informs us when we make a mistake in installing the measurement unit in the flash. The four batteries also have a protection circuit to stay aware of the remaining energy in them. The L group works so that it will not damage the flash or the battery if the unit of measurement is entered incorrectly ⏹
