New? Lithium Battery Advertisement

400AH battery with a .1C discharge rate (40A)? No thanks!

I see 100 amps
Still a bit light to drive a 2000 watt inverter

MEX, I assume they want to know what rickshaw company you own to know if you need 100 or 1000 battery every month.

Potential Ginzu Knife customers

There might be better but my Ginzu set is holding up good 15+ years.

Need vise grips to hold 1/4" thick handles. I use my knives every day. Compared to German knives, Japanese knives are very dificult to sharpen. So are genuine Katana swords. I thought Ron Popiel exited stage left from those hokey gimmick TV spots long before 2005.

A product that costs multiple times the expense of a proven competitor needs to live up to its claims. I know of no Concorde battery that will achieve specification cycles at specified Depth of Discharge. To parrot OEM claims is foolish. They would need almost EIGHT and 1/4 years of fully allowed charge and discharge every day to meet this claim. Or is it a claim justified by discharging to 80% of capacity?

The last time I was suckered was a purchase of AAA, AA and 9 volt batteries. This chemistry is clearly superior to nickel metal hydride and alkaline when it comes to standby lifespan but clearly not superior in any regard when it comes to equivalent load lifespan compared to NiMH or alkaline. I don't guess. I test with precision load and bench meters.

This is why my favorite car battery brand comes from Costco. If I decide I don't like its looks, back it goes. Much easier than arguing with a zit faced teenager at Wal*Mart who knows everything about anything.

When this full page lithium battery advertisement found me in China answering banal questions then handed over to someone with a private Yahoo email visions of stonewalling at a warranty claim at week 1 of service ran through my head.

To me, even a reputable USA lithium battery has one clear advantage: The ability to survive life at partial discharge. The reliance on an amp hour meter and averaged amp hour draw to guess if, yes or no, the battery will survive another night's heat blower drawdown, is not an advantage. At 800 dollars apiece the thought of buying one for now and a second for spare capacity is not enticing. This is a specialty toy of the wealthy. Their lifespan as compared to a well taken care of Concorde Lifeline is yet to be proven with hard numbers.
