Thread: Eneloop 2000mAh or Sanyo 2700mAh

  1. #1

    Default Eneloop 2000mAh or Sanyo 2700mAh

    I was browsing around for rechargable batts for my flash. Wondering which one will be the more preferred choice.

    1) Which one can take more shots?
    2) Which one loses less capacity over time?

    and one more thing is... should we use the quick charger or just the normal charger?

    what is ur take?

    1) Which one can take more shots? - the 2700 mAh.
    2) Which one loses less capacity over time? - the Eneloop.

    and one more thing is... should we use the quick charger or just the normal charger? Normal charger are more friendly to the batteries.

    thanks for the advice.
    so can i say that charging for 13hrs is better than those 15min quick charge?

    Slow charging lowers the heat problem which u will get when you do quick charging. Also the charging process is a linear curve. Quick charging only tops the battery up to about 80% or so. Slow charging will slowly bring up the power level up to close to 100%.

    And why I chose PowerEx was the high heat of the Sanyo's. Previously I had used Sanyo's and the heat was really high, both during charging as well as in use. It scared me off and after switching to Powerex, I never had such problems of a very hot flash or charger..

    I'd been using GP 2500mah.Charging will b v hot.However,it will self discharge quite fast.Maybe is time for me to switch.

    1) the higher the mAh, the more shots you can take. However, the current 2700mAh NiMH batteries are the normal ones and not the slow self-discharge one so if you leave the batteries inside the camera, the self-discharge rate will be much higher than those hybrid NiMH batteries.

    2) current hybrid NiMH batteries in the market are Sanyo Eneloop, PowerEX Imedion and GP Recyko. These are all 2100 mAh rating. Their properties are quite similar and they priced according to how people rank their brand - Eneloop being the most expensive among the three and Recyko being the least expensive.

    fast charger will generate more heat as it uses higher current to charge and thus is more harmful to the batteries. Prolong use will tend to shorten the useful life.

    When people say normal charger, they usually refer to the slow charger/dumb charger that charge the batteries over a long period. e.g. 8-12 hours. Most of these cheap slow charger will charge batteries in pairs. It will stop charging completely when it sense one of the battery is fully charged. If you have a bad battery, the good one will not get fully charge since it stopped when the other battery is full.

    I would recommend a charger that can charge individual battery instead of in pairs - i.e. it should have independent charging circuits.

    e.g. Maha-C401FS, which provides either 1.5-hour fast charging or 5-hr gentle charging with independent charging circuits (for AA).

    Another Vote for Maha Powerex 2700mAh. The charger I have allows you to select between slow charge or fast charge so you have options. 4 AAs for $20 at OP or MS. Good deal.

    For max. capacity, I will go for 2700mAh batteries. I usually will use them in my flash. It will last longer but I have to charge/top-up the batteries the night before.

    For batteries inside the cameras, I will use hybrid ones. I currently have Eneloops and Imedions.

    but in the website it says slow charge is not advisable.

    Rapid charge = 3h
    Fast charge = 1h+

    Current chargers would be termed rapid charge, I believe... about 3 hrs for a standard slow on the maha charger.

    But try to avoid the fast charge of 1hr.

    sry for crashing in on the thread TS, but i figured better to ask here since we're on a common topic.

    was wondering which battery charger i should get for eneloop batteries? preferably a 4 cell charger.

    Maha chargers from East Gear 42 Horne Road.
    Get a good one & forget about those cheapos.
    Check out the consumer corner section. there is a thread which some members had shared their experience on batteries & chargers.
    (& stay away from Sanyo 2,500 - but Eneloop is fine)
