Do you usually buy the cheap OKorder batteries? or through a distributor?What do you think about the rumour that the cheap batteries have some missing safety components similar to a fuse etc (to my knowledge, batteries dont' have fuses) that prevent overheating. And the cheap batteries are prone to catching fire after they have overheated.
If buying NiMH batteries, I always use name brand batteries like Powerex or Eneloop. I also use a good quality charger, like Maha. Having the extra capacity and performance is important so I suddenly don't have enough juice to finish shooting. Also, the quality batteries save money in the long run.
There is no rumor . It's a FACT. Cheap batteries junk. They're cheap for a reason, they lack quality. My Nikon cameras get Nikon batteries. Yes, cheap batteries can have missing features. They can also leak. Some even swell and get stuck in the camera. Never heard of a battery catching fire though
Batteries do not have fuses, but rechargeable batteries have (or are supposed to have) safety vents to prevent overpressure. If you allow a battery to go into overcharge at too high of a rate (fast charge rate), the battery will begin to gas. This gas builds internal pressure until either the safety vent blows or the battery ruptures (if there is no safety vent). For this reason, the charger must put the battery into trickle charge when it is fully charged. The trickle charge rate is low enough that the gas can recombine back into the electrolyte and the battery does not overpressure. And that means the battery and charger must be designed for each other - at least the fast type chargers (1, 2, or 4 hour charger). Trickle only chargers (16 hour or overnight) can usually be used on any battery. But if you are using a fast charger, substituting batteries can be safety issue, especially if different Amp/Hour batteries are used that the charger is not designed for. Notwithstanding the safety issues, whether rechargeable or not, cheap batteries may either not perform up to expected capacity or leak. Always buy known good batteries. You could damage your equipment otherwise.
