Despite the many warnings re LiIon battery dangers (which I also pass on to people) I have never seen a LiIon battery self immolate. … A lead-acid battery has a usefully flatter voltage discharge profile than a Lithium Ion battery and a 7Ah battery will happily exceed the LiIon current capacity even when rather discharged. …

As noted by others, if you want a battery that is a straight replacement for rechargeable AA cells then LSD (low self discharge) NimH will meet your need. … You need a battery, which is reliable even when having cold temperatures? Before eneloop was suitable for temperatures as low as -10°C - now even until -20°C. …

The EX-1 camera has an unusual feature - it will accept charging input from a 5 Volt "USB" power source and charge the battery while the battery is in the camera. … For cameras that do not have this charge-in-camera capability you would need a "5V USB power supply" to battery charger. …

Read ad carefully, as ever ebay Battery charger for Canon BP-511 EOS 50D 40D 30D 60 G6 …

I and others have answered those questions fairly well here -> Should I buy an original manufacturer battery, or is a generic brand OK?. … They all worked OK at first but after 5 to 100 photos taken all 3 cause camera to give a "incompatible battery message. …

Also, you are starfing out with FF (Faulty body, faulty battery). eg if GF works and FG (Faulty body, good battery) still doesn't then the issue is more likely to be with the body than the battery. … Look carefully at how the battery is intended to be retained and try to see what is wrong with the system. …

same battery each time to do this then modifying the battery is probably the best solution. … If you are accessing the battery via the battery door the very enthused may wish to add a cooling air line. …

If you have a genuine and suspect battery then. - Charge both fully. - Apply a load not above what camera may take. 1A is usually safe depending on battery capacity. … Usually Imax in mA = mAh capacity is safe. eg a 1600 mAh battery can be safely run at 1600 mA. Usually. Lower is safer. For 1 Amp R = V/I. For 1 cell battery Voc ~+ 4.2V. …

The level of flash output is relatively constant regardless of battery state across much of the battery range. … Flash charging time is a good indicator of battery state. …

If that makes no difference, remove battery from camera. Just opening the battery door so contact is broken should be enough. (ie camera will not turn on. … If cutoff current is low the battery gets more charge, it takes longer AND the battery cycle life goes down. …

Any battery that loses capacity or terminal voltage rapidly when unloaded is highly suspect. Note that some systems place a continuous light load on the battery when in standby or sleep modes. … The total energy in the battery is released in a flaming over 10 to 10s of seconds. If this happens inside your camera you'll be needing a new battery, AND a new camera. …

Battery state can be roughly determined with a voltmeter. New Alkaline open circuit will be > 1.6V. Dead Alkaline well use will be under say 1.3V (rises to this from much lower after use). … Placing many AA NimH cells in a trouser pocket with keys and coins may lead to substantial bystander amusement and great pain or even burns for the battery carrier. …

(3) Expert only: Use a LiFePO4 (NOT LiIon) battery plus a dummy battery. A LiFePO4 cell gives up to 3.6V and typically 3.3V down to 3V when operating. … (4) Some people report success after cleaning the battery contacts. Seems unlikely but worth a try. …

You can use a 5V output powerbank to charge your battery by using a relatively low cost after-market charger which is designed for this specific purpose. … Larger cameras (eg DSLRs) often use 2 x LiIon cells in series to give a nominal 2 x 3.6 = 7.2V battery with Vmax = 8.4V. …

While I understand that a bad contact between the camera body and the lens can cause a variety of issues, ... is it possible for a bad lens contact to cause the camera to falsely think its battery is …
