Px625 Battery
Overview
Product sourcing insights & recommendations
The phrase 'PX625 battery' refers to the classic 1.35V mercury battery, widely used in vintage film cameras (e.g., Leica M5, Canon F1). Since mercury batteries were banned for environmental reasons, the market has pivoted toward several replacement technologies, each with distinct technical trade-offs.
Market Trends & Insights
* The "Accuracy Crisis": Vintage camera light meters were designed for a steady 1.35V output. Modern Alkaline (625A/LR9) replacements AmazonAlibaba output 1.5V, which typically causes underexposure (about 1 stop) and loses accuracy as voltage drops during use. Photo
* Niche Enthusiast Demand: There is a sustained, high-value niche for Zinc-Air (e.g., WeinCell MRB625) and Silver Oxide batteries with voltage-reducing adapters. JoshualowcockPhoto
* Shift to Adapters: The "gold standard" market trend among serious collectors is the MR-9 adapter, which uses a Schottky diode to drop a stable 1.55V silver oxide cell to the required 1.35V. Joshualowcock
PX625 Replacement Comparison
| Battery Type | Voltage | Pros | Cons |
|---|---|---|---|
| Zinc-Air | 1.35V–1.4V | Accurate voltage; direct fit. Photo | Short life (1–3 months) once activated. Photo |
| Alkaline (625A) | 1.5V | Cheap; long shelf life; direct fit. Amazon | Inaccurate metering; sloping discharge. Photo |
| Silver Oxide | 1.55V | Very stable; long life; no leaks. Photo | Requires adapter or camera recalibration. Photo |
Sourcing Opportunities
* Retail Performance: Top-selling alkaline PX625A variants on consumer platforms see monthly volumes of ~460 units with high ratings (4.5★), indicating strong demand for simple, non-critical replacements. Amazon
* B2B Wholesale: Large-scale manufacturers (e.g., Winpow, Picell) offer bulk alkaline 625A batteries for as low as $0.09/piece, primarily targeting high-volume retail or budget camera repair. AlibabaAlibaba

IEA (2026), Global battery markets are growing strongly – and so are the supply risks, IEA, Paris https://www.iea.org/commentaries/global-battery-markets-are-growing-strongly-and-so-are-the-supply-risks, Licence: CC BY 4.0 Copy to clipboard ... The global lithium-ion battery market exceeded USD 150 billion in 2025, an increase of over 20% from 2024, but its economic and strategic significance extends far beyond market size. Battery factories in Europe and the United States rely heavily on imports for the majority of their battery components, which come mostly from China. The lack of investment in midstream supply chains in these markets poses a growing risk to global supply security, a topic that will be examined in depth in the upcoming IEA publication Energy Technology Perspectives 2026. As the strategic role of batteries in energy systems and beyond continues to rise, the IEA will continue to monitor these trends in order to provide timely analysis and policy advice. Extensive analyses on the supply chain security of batteries and other energy technologies will be released in the IEA’s forthcoming flagship technology publication Energy Technology Perspectives 2026. Global lithium-ion battery deployment in 2025 was six times as high as in 2020. Electric vehicles remain the dominant driver of demand, with global sales reaching a new record and accounting for one-in-four cars sold globally. Electric vehicles account for more than 70% of total lithium-ion battery deployment.
Electric vehicle batteries – Global EV Outlook 2026 – Analysis ...
www.iea.org
Electric vehicles (EVs) remained the primary source of global battery deployment, accounting for more than 70% of the total in 2025, slightly down from almost 80% in 2024. In 2025, EV battery deployment reached 1.2 TWh, an increase of almost 30% compared to 2024, and more than 7 times greater than in 2020. In 2025, LFP batteries accounted for over 55% of EV batteries deployed globally, up from nearly 50% in 2024. Deployment remains heavily concentrated in China, but uptake is also expanding rapidly in other EMDEs. In the United States, the share of LFP in EV batteries almost halved in 2025 from an already low base in 2024, reflecting higher tariffs on Chinese imports and more stringent sourcing requirements linked to the EV tax credit that was available until the third quarter of 2025. At the same time, CATL’s overseas activities continued to grow in importance – in their 2025 interim report, they indicated that almost 35% of revenue came from overseas activity, up from 30% in the same period of 2024.

Lithium-ion pack prices fell to USD 108 kWh in December 2025, a 22% drop from 2023, enabled by cathode-material deflation, manufacturing scale gains, and broader lithium iron phosphate adoption.[4]Reuters, “Chinese Battery Pricing,” reuters.com Chinese producers leveraged vertical integration to achieve spot prices of USD 53 kWh in Q2 2024, undercutting Western peers that lack similar scale or subsidies. Utility-scale battery installations are forecast to hit 18.2 GW in 2025, up from 10.3 GW in 2024, as operators replace aging gas peakers and integrate solar fleets exceeding 300 GW worldwide. India’s tenders reached 6.1 GWh in Q1 2025 under rules requiring storage to guarantee a round-the-clock renewable supply. ESS Inc. deployed 500 MWh of iron-flow units by year-end 2024 to industrial customers and island grids that prioritize supply-chain security over round-trip efficiency. In August 2025, batteries shaved 6.6 GW of net peak load in California, matching six combined-cycle plants and averting blackouts during a heatwave. Nickel sulfate deficits persist because Indonesian laterite projects prioritize stainless-steel output, widening the Class 1 versus Class 2 price spread to USD 4,000 t in 2025, the decade’s peak. Automakers mitigate by pivoting to lithium iron phosphate and sodium-ion cells that remove nickel and cobalt, evidenced by CATL’s commercial sodium-ion production for Chery and JAC in 2024.

In the first half of 2025, global EV battery installations reached 504.4 GWh, marking a 37.3% year‑on‑year increase. Electric vehicles, including BEVs, PHEVs, and HEVs, remained the largest consumers, accounting for over 85% of demand. CATL led the market with 190.9 GWh (38% share), followed by BYD at 89.9 GWh. Overall energy sector demand for batteries, including EVs and storage, hit an unprecedented 1 TWh in 2024, with weekly demand surpassing annual levels from just a decade earlier. The battery market is expanding quickly in terms of structure, due to faster electrification and more energy storage systems being used. In 2024, shipments of lithium-ion batteries around the world reached about 1,545 GWh, which is an immense rise over the previous year. Electric trucks showed the fastest growth, with demand rising 75% in 2024, now representing about 3% of total EV battery consumption. For instance, in July 2025, Nordic Semiconductor's nPM2100 Power Management IC is now being made in large numbers for use in primary batteries. It is made for devices that use non-rechargeable batteries, like alkaline or lithium coin cells, and it makes them use less power and last longer.
