I concluded that the easiest solution for most people is to substitute an inexpensive #675 hearing-aid battery (with a spacer ring if needed to fit your battery compartment).
While Wein cells are indeed effective for this, photographers have often speculated whether there is anything special about them. The Wein replacement for a PX13 or PX625 battery does have some physical differences from a 675.
The Wein battery has the same dimensions as the 675 hearing-aid size, but adds a metal ring crimped around it. I have no insider knowledge of how Wein produces these batteries; and my only test equipment consists of a simple Radio Shack multi-meter. Yet I made some curious discoveries about the voltage of zinc-air batteries (of both types), which photographers using these cells ought to know about. While researching my earlier post, I became curious exactly how much current a typical camera meter circuit was drawing. It was more convenient and accurate to use a simple resistor rather than a camera as my dummy load when comparing batteries.
But in fairness, we should note that even this solution can give different voltages depending on the specific diode chosen, and the current draw of the meter circuit. Given all these uncertainties, I continue to feel hearing-aid batteries are the most sensible real-world mercury replacement for many photographers. Hi Mike, an extra few tenths of a volt pose no danger of frying the meter—it’s just an accuracy issue. The short answer is that a zinc-air hearing aid battery (or a Wein cell if you care to pay the extra price) will be fine, *if* you turn on the meter and uncap the lens a few minutes before you start taking meter readings.
It is generally accepted that the most economic and practical depth of discharge (DOD) for an AGM battery is 50%. This begs the question, what Ah rating of AGM batteries would be the equivalent of the 3.8 kWh useable energy of the Lithium-ion battery?
Based on this you might immediately conclude that Lithium is not cost effective, however useable energy compared to price is only part of the story. Increasing the current draw (as the graphs below show) can affect the useable energy available and battery voltage. Much that we have seen in the discharge process is also true in the converse process of charging. Higher charge rates will heat up the battery (temperature compensation, voltage sensing and good ventilation are absolutely needed in such a case to prevent thermal runaway), and due to internal resistance the absorption voltage will be reached when the battery is charged at only 60% or less, resulting in a longer absorption time needed to fully charge the battery.
High rate charging will therefore not substantially reduce the charging time of a lead-acid technology battery.
Depending how you treat a battery you can reasonably expect the range of cycles below, subject to the DOD and the battery banks being properly sized for the loads.


No matter what battery choice you make there is also both a capital cost and technological risk at the outset.
To maximize the life of your Rolls AGM battery, it is important that it is properly charged. Bulk stage - the charger should deliver the initial current I1 until the voltage limit U0 is reached.
Absorption stage - the charger should maintain the voltage U0 until the current tapers to I2.
Float stage and termination – the charger can maintain the current I1 indefinitely or until the charger is shut off or unplugged. Constant Current Charger - IUIA constant current charger can also be used, however it is important to adhere to the termination criteria mentioned below to minimize the chance of excessive over-charge.
Bulk stage - the charger should deliver the initial current I1 until the voltage limit U0 is reached. Absorption stage - the charger should maintain the voltage U until the current tapers to I2.

Do the small blue spheres represent positive or negative charges?Which side of the batterey is labeled positive, and which side is negative?How can you determine which side of the battery is positive and negative just by the location of the blue charges? This can be important in making electrical contact with some battery compartments, for example the metered Yashica Mat models. By making temporary connections to the battery compartment of my Olympus OM-1, I found that with its meter needle centered, it drew roughly 0.2 milliamps from its PX-13 mercury cell.
The voltage of a mercury or silver-oxide battery scarcely changed when put under this load—a drop of maybe 0.005 volts. Far more significant for accurate exposures is that you turn on the meter several minutes before taking a reading. By introducing this small voltage drop, a very close approximation to the mercury battery voltage can be obtained.
When you go out shooting, switch on the camera, uncover the lens cap, and leave it that way. For Lithium-iron-phosphate (LiFePO4 or LFP) which is the safest of the mainstream Li-ion battery types, 80% DOD is used. This was fine in the days of light loads, but as the number of loads and the size of loads has increased over time, we also need to look at high short term loads, medium and longer term ones for differing types of equipment. Don’t be put off by the large generator sizes shown below, as this blog merely shows a range of scenarios.


It is worth bearing this in mind as this entails time, installation and transportation costs, which further negates the higher initial capital cost of Lithium as does the lower cost of recharging Lithium. If you are in a position of having the capital for the higher upfront costs of Lithium, you might find that life is easier and that choice is a cost effective one over time.
Select the battery voltage and little stick figures move charges from one end of the battery to the other. With either zinc-air battery type, the voltage will be too high immediately after turning on the camera—possibly leading to underexposure. Frans de Gruijter discusses both these factors at some length in his definitive battery-adapter article downloadable here. As we use only 50% of the battery we can see that the voltage will still be 24 V at 50% DOD for a 5 Amp load over 10 hours, and therefore we would have consumed 50 Ah. The reason we plot Discharge Capacity (instead of Discharge Time) is that Lithium has a higher and more stable terminal voltage than AGM, so plotting the curves with Discharge Capacity in mind gives a more accurate comparison of the chemistries, showing that Lithium increases useable energy at higher loads due to higher and more stable terminal voltages.
Personally I think the time is right to consider Lithium in the marine industry as a cost effective, reliable, high performance solution. Just note that the Freshdesk service is pretty big on some cookies (we love the choco-chip ones), and some portions of Freshdesk may not work properly if you disable cookies. Once you become aware of this effect, you will definitely notice your needle drifting for the first few minutes, even when metering a scene with unchanging light.
At the extremes we might have air conditioning running for 10 hours using 10 kW, compared to an LED light using 100 Watts in that time. Whilst you may consider this a grey area (in part too due to the varying internal resistance of batteries also) it is probably the only true way to compare the technologies.
First let’s compare charge efficiency of Lead Acid on the left to Lithium on the right, during the complete charge cycle. Note this does not take into account, the ageing of the batteries, temperature derating or the effect of higher loads. Charging the last 20% of a lead acid technology battery is always slow and inefficient when compared to Lithium. Good management practices are your insurance against early failure, regardless of the technology used. With a large pack as shown below to achieve this, it becomes clear just how heavy Lead Acid can be compared to Lithium. This is borne out in the fuel costs (or whatever charging source you use) in the images further down.
