    OT? Is there an Android smart-phone app that limits battery charge % to below 90%?

    Sorry if OT ... I have a LG Arista entry level smart-phone from about 2016 or '17 with Android 7.1 Nougat. I try to limit the charge to 80% to 90%, but it regularly happens that I carelessly allow it to get to 100%. My older Dell laptop and newer Lenova laptop (both Win-10) have this...

    [OT?] Possible fix for defective 40v Black&Decker weed eater battery?

    Stale thread .... sorry (and also thanks for the reply which I was rude not to reply, and also didn't comprehend) Since the OP, I've gotten more experience with LI-ION batteries and may understand the reply better. My impression is that the weed-eater battery has multiple standard cells, such...

    Curious about FREMO P201A external battery: Li-Ion? Ni-Cad? Other? Use with ff cam?

    Works well to charge the battery, and also as an external battery to extend the count of shutter activations from about 300 to 1500+.

    Curious about FREMO P201A external battery: Li-Ion? Ni-Cad? Other? Use with ff cam?

    Thanks for the replies. I did get a reply from FREMO ... indicating their P201A is Li-Ion. It seems to work fine for charging a low smart-phone. I haven't tried it yet with the Sony full-frame a7Rii, or an ASUS 10" Intel Atom laptop.

    Curious about FREMO P201A external battery: Li-Ion? Ni-Cad? Other? Use with ff cam?

    I'd hoping to get info on the FREMO P201A external battery: http://www.newegg.com/Product/Product.aspx?Item=N82E16875790061 I checked with Fremo's tech support, and their reply was "has a Lithium battery" ... The Wiki article on "Lithium Battery" mentions it is disposable (non-rechargeable)...

    Smart charger for various sizes of Li-Ion camera batteries?

    I purchased a Wasabi 2 battery + charger bundle for my Sony a7x family camera. I noticed the charger has a removable module that the FW-50 battery itself fits into. That made me wonder if a "smart charger" for camera Li-Ion batteries would be feasible with capabilities like my Maha MC-9000...

    Evaluate Li-Ion batteries with simple digitial multimeter?

    Is it possible to use a simple digital multimeter to measure Li-Ion batteries to evaluate their status for expected performance and remaining useful life? I'm mostly ignorant and challenged when it comes to electronics. I've got a simple TEK-10709 multimeter from Walmart that I barely know how...

    Smart charger for various sizes of Li-Ion camera batteries?

    Is there an equivalent of the Maha MH-C9000 AA/AAA smart charger that would work for various sizes of Li-Ion camera batteries? My various cameras have 6 different sizes of Li-Ion batteries (Canon Rebel, Canon f.f., Nikon One, Sony f.f., Lumix p-n-s, Canon p-n-s). All have separate chargers...

    Useful life of Li-Ion only 2-3 years from when manufactured?

    I came across the following statement in a photography forum, and wanted to check on its validity: > "Lithium Ion batteries have a limited lifespan of 2-3 years (from time of manufacture)." http://www.dpreview.com/forums/post/56787829 My less-than-informed impression was that well made...

    With MH-C9000, does reported Discharge Capacity tend to be spec of highest interest?

    Thanks to all for the helpful, patient replies.

    With MH-C9000, does reported Discharge Capacity tend to be spec of highest interest?

    I'm fuzzy on what you mean by "discharge current". In a flashlight, would that be the "drain", like "normal brightness for 6 hours"? What about an external camera flash? Should I try to keep track that the batteries allowed 104 flashes? I wouldn't be able to do that.

    Is any of the info in the Maha MH-C9000 FAQ obsolete or less than best practice?

    Semi-newbie with MH-C9000 I recently came across this FAQ on the www.mahaenergy.com ... http://www.mahaenergy.com/faq-c9000/ Is any of the info of dubious accuracy? Is some obsolete? Is anything "best practices" for new owners (especially non-EE's or non-material engineers), but there are...
