If it still has not recovered to minimum for the CTEK to work, then the battery is dead. Then I will pull that charger and use the CTEK. Then I will switch it to 12A for about 2 minutes.
Often in these cases, I use my Mastercraft bulk charger, set it to 2A, and leave it for an hour first. I have a small Black&decker one, and it needs a minimum of 6V to start. So depending on the model, if the voltage drops below this threshhold, the charger either displays a fault, or doesn't even start. The US 800 charges from 6V, while the XC 800 charges from 3V". I know CTEK states " Most models can handle batteries as low as 1.5V.
HOME DEPOT BATTERY BUDDY FULL
Full as in "like new from store" is probably also not possible with this or any other device.įrom Zero, most "smart" chargers will not even start a charge. On the other end, by "full" I mean "cranks at healthy speed for some minutes" which might be 8Ah (240A * 2 minutes) or even less. I'm not sure revival from zero is even possible. Your math is fine, but "dead" isn't zero it's "clicks instead of cranks" and a fair way from zero. We're both making assumptions that won't always be valid.
SKU is 1000846237 (thanks CMAG for pointing it out) The rings are nice, as you can leave them connected at all times to your battery terminals, and during the riding season, unplug and tuck the cable away, not having to remove the rings from the battery at all. Comes with the clamps, and ring attachments.
These are great for motorcycles, lawnmowers, marine batteries, atvs, even car batteries, that will be stored over time, keeps the battery charge topped up, then shuts down and periodically checks to see if a trickle charge is needed again.Ī definite steal at $17, I didn't pick one up, as I am already using one of the Mastercraft Eliminator ones, but this is a smaller unit, simple plug and play. Another Home Depot yellow tag clearance deal.Ĭhatham store has the Battery Tender JR 12V, 750 mA battery maintainer, on sale for $17, normally $50.Īmazon and Canadian Tire have them for around $50 regular as well.
