    Battery recharger exploded

    I have a couple of Lacrosse BC700s since around 2011/2012 and it hasn't failed yet. I just used one of mine for a Test cycle last weekend with some older AA Eneloops. There was a known problem with the BC900 way back (you might find old threads somewhere in here about that issue) If I recall...

    Charging From a Laptop?

    I'm all for safety advice but for these batteries this is from the manufacturer from their data/fact sheet: A few of the other more reputable companies like Nitecore and Klarus also make these protected 18650 cells with built in microUSB charge port. Some of these will charge with max 1A...

    Charging From a Laptop?

    Actually, WalkIntoTheLight was referring to the charging CURRENT (mA) not the battery capacity (mAh). The Streamlight SLB26 18650 2600mAh battery with built in micro USB charging socket (https://www.streamlight.com/products/detail/index/sl-b-26-usb-battery) will charge fine from a PC's USB...

    Li-Ion batteries for Australian CPF members

    I actually ended up getting my Keeppower 14500 1000mAhs from supersport600 just last week as well. Didn't know about his involvement in the protection circuit designs. Have previously bought my 18650s from him, so was glad when he started stocking the 14500 1000mAhs. Getting them from Illum...

    Li-Ion batteries for Australian CPF members

    Keen to know how your illumn order goes. I have been after the Keeppower 14500 1000mAhs, but can't find any local stockist. The AU based torch stock the 800mAh and 840mAh at the Australian prices (high). I've bought 18650s and other 14500s from ebay as well since my goto...

    USB magnetic charger for Eneloops

    I've occasionally had this happen with some of my AA/AAAs when traveling with only the Olight UC charger. If you have a good NiMH > 0.8V, you can try the "jumpstart" trick for bumping up the voltage of the low voltage cell. Place both cells on something conductive (like a paper clip or metal...

    Ikea Ladda Brown discontinued?

    In Australia they also changed the Brown Laddas to Chinese made ones around mid 2019. But we can still get the Brown Laddas. At about the same time, they increased our price for the Japanese made White Laddas almost double, from AUD$8 to AUD$15 for the 4 pack.

    Xtar VC4 charging problem

    sorry mrmarcie - haven't logged in for a while. With my VC4, I tried: Changing the USB - Barrel connector cable Changing the power supplies - ended up trying 5 different ones all capable of > 2.4A at 5V, including some multiport USB chargers Testing new batteries, as well as older batteries...

    USB (500mA) charger for AA/AAA batteries - does it exist?

    My bad, typo. I will fix it now. I meant the Xtar XP1. I have too many Xtar chargers, including the MC0, and the MC1 or the MC1Plus and the VP1 and XP1, and the VC4, and I just ordered the VC4s.

    USB (500mA) charger for AA/AAA batteries - does it exist?

    The Xtar VC4 does not work with a 5V 0.5A input (like when you connect it to a USB 2.0 or USB 3.0 socket on a laptop or PC). It really needs a good 5V 2A minimum USB charger. The Olight Universal Magnetic charger says it needs 5V 0.8A input, but I've just plugged mine in to the laptop with a...

    Xtar VC4 charging problem

    The first thing I thought was that the power supply was at fault, so I tried a few others, but all with the same result when charging NiMH. I have used a Blitzwolf QC3.0 BW-S7 40W 5 port charger (with nothing else plugged into the other USB slots), and an Anker PowerPort 5 40W 5 Port charger...

    Xtar VC4 charging problem

    I have the VC4 - the one with the USB A cable to barrel connector for the power supply. The Dragon is the Xtar VP4. I have done some more testing, and it seems that NiMH charging is now very odd. It worked with older Energizer 2300mAh cells from about 2012. But I only charged 3 x AA cells...

    Xtar VC4 charging problem

    Cheers. The high IR might be the issue. Strangely, I just tried some older Energizer 2300mAh AAs from about 2012, and they seem to be charging fine. I have another batch of 4 AAs that I will charge again once these are done. It seems only my Eneloops are giving me this issue. I think they...

    Xtar VC4 charging problem

    Recently my Xtar VC4 has not been functioning correctly. I got it in 2015 and it has been lightly used as a spare charger, mainly as a plug and play charger for the family to use. But it's been working fine as far until now. Now when charging 4 x NiMH cells, it appears to work correctly...

    Olight universal charger question

    https://olightworld.com/index.php?route=product/product/info&product_id=275 If you see under "specifications" this is normal operating behaviour when plugged in to USB power source but with no battery connected. It is in "standby" mode. Solid red light is charging. Solid green is charging...
