    battery charger for lead acids, ones that runs off nominal 12V DC

    Since the specs on the generator indicating it is for charging lead acid batteries (i.e. automotive type), I expect that it basically has a voltage regulator just like a car alternator. Common nomenclature is that the car is a 12V system, even though more realistically it is a 13.6v system...

    battery charger for lead acids, ones that runs off nominal 12V DC

    Do you even know if the 12V circuit on the generator is regulated at exactly 12v? I really would suspect that it is made for charging 12v lead acid batteries directly (i.e. putting out the 13.6v voltage as reverenced above or at least something that would work.)

    18650 Cell Phone Charger

    Home Depot is now selling what appears to be single 18650 cell lithium tools. They have a "USB power supply" in their kit. Of course, they have wrapped their batteries in a plastic case with a protection circuit, but if you are decent at modding, you could likely open up the case and use your...

    Help me decide MH-C9000 or BC-900

    I want to thank everyone who provided input. I've been convinced that the Maha is the one that I will get. The occasional LaCrosse meltdown really didn't come into play. Probably the biggest reason is the default charge rate for the Maha as pointed out early on in the thread. Sounds like I...

    Help me decide MH-C9000 or BC-900

    So I'm finally ready to get a good charger that I won't have to upgrade next year. In what I have read it seems the MH-C9000 may have a slight edge on information provided about each cell status, but with the LaCrose on sale at Thomas Dist. I'm wondering if it is worth the extra cost...

    Taking a laptop battery apart - can I use these?

    These will be unprotected cells. In the laptop pack, the protection is handled by the circuit board at the bottom of your first photo. If you are measuring 1.2V on a cell, that is extremely discharged. (I'd expect that on one of the pairs, not just a single cell). Are all the cells this low...
