Camera batteries

A third-party battery costs three times less than an original, but they do not all talk to the camera body in the same way.

Recent bodies read a chip inside the battery to display the remaining percentage and sometimes to permit in-camera charging. A third-party pack without that chip still works, but the body falls back to a three-bar gauge, or refuses to charge over USB. That is the real deciding factor, more than the claimed capacity. For each reference we state whether the chip is present, the capacity we observed in number of shots, and exact compatibility with the ranges concerned. Carrying two batteries remains the rule in any case, since cold halves endurance on a winter shoot.

LP-E17 Canon LP-E17 battery for EOS R and Rebel DSLRs

Canon LP-E17

See price and availability (40)

The genuine Canon LP-E17 keeps EOS R mirrorless bodies and Rebel DSLRs shooting, so a dead battery never means a missed photo or a cut video take.

  • Voltage: 7.2V
  • Capacity: 1040 mAh
  • Type: Lithium-ion (genuine Canon)
  • Compatibility: EOS R8/R10/R50/RP, Rebel SL3/T8i/T7i
  • Genuine Canon battery, no error messages or limits
The Canon LP-E17 is the factory battery for Canon's mid-range EOS lineup, a 7.2V, 1040 mAh lithium-ion cell rated 4.8 stars across more than six thousand Amazon reviews. It powers the EOS R8, R10, R50 and RP mirrorless bodies, plus the Rebel SL3, SL2, T8i, T7i and T6i DSLRs and the M6 Mark II. The genuine Canon part avoids the error messages and disabled features some third-party cells trigger, and shows an accurate charge level on screen at all times. A spare LP-E17 is standard kit for event shooters who cannot risk a dead battery.
In-depth reviewRead our full review → 4.1/5 The genuine LP-E17 keeps a simple promise: 7.5Wh that matches the rating printed on the cell, seamless compatibility across 14 Canon bodies and three mounts since 2015, and no known structural fault on the genuine part, at a time when Canon itself warns about real risks on some non-genuine references. On optical-viewfinder DSLRs, battery life climbs to 800, even 1070 shots per charge, comfortably enough for a full day's shooting. Its limit is size: on the full-frame EOS RP and R8, electronic-viewfinder battery life drops to 210 and 220 shots, well behind bodies fitted with the LP-E6NH, which packs over twice the energy. Charging stays standard (2 to 2.5 hours) with no fast option, stretching to about 4 hours below 50 °F (10 °C), and the price actually seen runs well above compatible references. A safe, honestly limited buy, more compelling on a DSLR than on a full-frame body used continuously.

Sony NP-FW50

See price and availability (24)

Run out of battery mid-shoot and you lose the moment. The genuine Sony NP-FW50 keeps Alpha and RX10 bodies powered with none of the guesswork.

  • Voltage: 7.2V
  • Capacity: 1020 mAh
  • Type: Lithium-ion (genuine Sony)
  • Compatibility: Alpha A6000/A6400/A7 II, RX10 series
  • Genuine InfoLITHIUM cell, accurate in-camera readout
The Sony NP-FW50 is the factory battery behind a long run of Sony mirrorless cameras: a 7.2V, 1020 mAh lithium-ion cell that still powers plenty of APS-C Alpha bodies today. It fits the A6000, A6100, A6300, A6400, A6500 and A5100, the full-frame A7, A7 II, A7R II and A7S II, the RX10 II through IV, and the ZV-E10. Buying the genuine Sony part means the camera reads the charge level correctly, with the overcharge and overheat protection built into every InfoLITHIUM cell. A second NP-FW50 is the standard fix for a body that never lasts the day.
In-depth reviewRead our full review → 4.3/5 The NP-FW50 equipped the majority of Sony mirrorless cameras for years, and it still keeps its promise today. Its real capacity comes close to 95% of its rated 1020mAh, a solid result that puts it ahead of several compatible rivals tested under the same conditions. As a genuine Sony battery, it's recognized without reservation by every compatible body: precise display of the remaining percentage, no warning message, no crippled function. Its compatibility spans a wide range, from APS-C mirrorless bodies to the early full-frame models, as well as the RX10 expert compacts. One point deserves attention: this format gave way to the NP-FZ100 on every Sony body released from 2017 onward, and the two are not interchangeable, and Sony publishes no official cycle-count figure for this reference. For anyone who already owns a compatible body, the official NP-FW50 remains the safest option for a spare or a replacement.

Replacement battery for Sony Alpha A7 IV, A7 III, A7R V, A9 II, ZV-E1 and FX3. Restore your device's original runtime when the battery gets tired.

  • Capacity: 2280 mAh
  • Compatibility: Sony Alpha
  • Type: Lithium-ion
  • Use: Replacement battery
  • Original runtime restored, Sony Alpha

Check your original battery reference and the exact model of your device before buying to ensure compatibility.
In-depth reviewRead our full review → 4.5/5 The NP-FZ100 succeeded the NP-FW50 in 2017 with a sharp jump in capacity, and it still keeps that promise years later. Its real capacity reaches up to 99% of its 2280mAh rated value in a comparison covering thirteen batteries, a result that puts it ahead of several newer compatible rivals that advertise a higher rated figure yet actually deliver less than the original Sony cell. As the official battery, it's recognized without reservation by every compatible body, a lineup that covers nearly the whole of Sony's current high-end Alpha range plus the FX3 video body. Battery life in number of shots varies widely by body, from 430 to over 800 shots under the CIPA standard. Sony doesn't publish an official cycle-count figure, but the available feedback suggests a useful lifespan of at least several hundred cycles over several years. For any recent Alpha body, the official NP-FZ100 remains the safest choice.

In-depth reviewRead our full review → 3.2/5 The Otech NP-FW50 positions itself as a compatible alternative to the genuine Sony battery, at a price roughly 64% lower. One early signal is reassuring: its claimed 1020mAh matches Sony's own rated figure exactly, without the inflated numbers some cheap third-party batteries claim, and market experience shows those are usually the ones that deliver least against their promise. That reasoning, though, is by analogy with other brands in the same segment, not a measurement specific to Otech itself: no independent data on this exact brand was found in any language. Otech is a real, identifiable French company, a useful point of contact if something goes wrong, though that's no substitute for an independent check. Like any non-Sony battery on this system, it also carries the standard risk of a startup warning message and a future firmware update restricting how it works. For an occasional backup battery, the price gap remains tempting.

Compatibles cost three to five times less and work well as spares. On recent Canon, Nikon and Sony bodies, however, an authentication chip may block the remaining percentage display, or reject the battery outright. Check the stated compatibility with your exact body reference before buying.

Cabin, always, like any lithium battery. Carry them in their original case or with the contacts taped over, because a short circuit between two bare batteries in a pocket is the most common cause of incident. Most airlines cap spares at twenty batteries per passenger.

The CIPA figure printed in the specifications gives an order of magnitude: 300 to 400 frames for a full-frame mirrorless, 800 to 1,200 for a DSLR thanks to its optical viewfinder, which draws nothing. In practice, using the screen, stabilisation and video often halves that number.

Below 5 °C the internal resistance of lithium cells rises and voltage falls faster: the camera thinks the battery is empty while energy remains. Keep a spare in an inside pocket, against your body, and rotate the two. Once warmed, a battery declared dead often gives back 30 per cent of its runtime.

Most bodies released since 2018 allow it, which means you can recharge from a power bank on assignment. Mind the distinction: some models only charge when switched off, others accept continuous power while shooting. That nuance appears in the manual under USB charging and USB power delivery.

At 40 to 60 per cent charge, dry and between 10 and 20 °C, never in a camera bag left in a car. A battery stored full for six months permanently loses 5 to 10 per cent of capacity, and one stored empty risks a deep discharge that makes it unrecoverable.
