Can I use an Energizer charger with eneloop batteries?

Eneloop batteries can generally be charged with any kind of NiMH battery charger. Duracell, Energizer and no-name. But to keep things simple, you better stay away from these 2 kinds of chargers: Ultra fast chargers and Dumb chargers. Ultra Fast chargers use a very high current to charge your batteries.
A.

Can you charge any rechargeable battery with any charger?

Not significantly. So long as it is done using a properly designed smart charger, most NiMH batteries can be recharged in about an hour without any damage or significant reduction in their life. However, NiMH batteries must only be rapid charged with a charger specifically designed for charging NiMH batteries.
  • Can I use Eneloop charger with other batteries?

    Answer: Those AmazonBasics high-capacity batteries are most likely rebranded Sanyo XX cells, so naturally you can recharge them with Sanyo eneloop chargers (or any other good-quality NiMH chargers). It charges in pairs only, and takes 12 hours to recharge any batteries - regardless of capacity. I do not recommend it.
  • How long does it take to charge a Duracell rechargeable battery?

    Value charger/CEF-14 - Charge any AA/AAA Batteries. The Duracell Ion Speed 1000 NiMH Battery Charger will recharge your batteries in 4-8 hours* with 1000 mW** of charging power.
  • What is the difference in NIMH and NICD batteries?

    Answer NiMH refers to Nickel Metal Hydride and NiCd refers to Nickel Cadmium. The major differences between the two types of batteries are is capacity, memory effect and environmental friendliness. NiMH batteries have high capacity, no memory effects and environmentally friendly.
B.

Can you charge Duracell batteries in any charger?

I recharged Rayovac AA rechargeable batteries but the manufacturer shouldn't matter (Energizer, Duracell, etc). The EBL charger package states it will charge AA/AAA NI-MH/NI-CD rechargeable batteries. It can charge Energizer "rechargeable" batteries, not the standard alkaline batteries.
  • Can you check an alternator by disconnecting the battery?

    If you're tempted to test an alternator by disconnecting the negative battery cable, don't do it. A good alternator may indeed keep the engine running, but it was never a good test. In the pre-computer days, you could pull it off without damaging anything. Today, you risk frying every electrical device in your vehicle.
  • Can you drive a car without a battery?

    Yes, an automobile can run without a battery, if the alternator is large enough to support all of the electrical needs. This is because your alternator is enough to keep the car alive and driving since the motor is already on, although you probably won't be able to use accessories like the radio, even turn signals.
  • Can you push start an automatic car with a dead battery?

    Either the automatic gearbox prevents rolling the car at all or there is an open clutch which cannot be closed manually. So if you want to be prepared for your automatic car not starting because of a dead battery, put a jump start cable in your trunk and/or sign a membership with a road assistance organisation.
C.

How long does it take to fully charge eneloop batteries?

Compared to conventional battery chargers that take more than twice the amount of time to recharge batteries, the SANYO 4-position Ni-MH rechargeable battery charger can completely recharge fully discharged AA Ni-MH batteries in approximately 10 hours and 7 hours for AAA Ni-MH batteries.
  • Do batteries die in the cold?

    A: Cold weather is often fingered as the culprit when car batteries die, but actually warm temperatures do the most damage to them. But car batteries usually go dead in cold weather mostly because damage done during the summer doesn't show up until the battery is more taxed.
  • Do batteries get hot when charging?

    Current is flowing in the battery during charging and discharge. A battery can be modeled as a voltage source in series with a resistor. Older or poor quality batteries conversely heat up more. Also, the faster the battery charges, the hotter it will get (more current means way more heat).
  • Are household batteries recyclable?

    Outside of CA it is legal to throw single-use alkaline batteries in your regular trash however we strongly encourage you to recycle them instead. Many cities and counties will collect single-use batteries during their household hazardous waste collection events.
