Shorai Battery

If you run a battery down to around 8.5 volts (or lower) most optimate/optimizer type trickle chargers won't charge it......but if you hook up the flat battery to another battery that's got a bit of life in it (pos to pos and neg to neg) then hook up the charger it will often fetch the dead one back.......leave both batteries on the charger for a day then try the original dead one on it's own......I've had success with this a few times over the years.....only once did it fail as the battery was too far gone and plates had distorted (lead acid battery)

I ran a Shorai Battery to low wouldn’t recharge with a trickle charger. Read this somewhere you put regular battery charger on it not to long brought it back to life. My safe someone some money like with Me

Is it a lithium battery? Must be VERY careful recharging any lithium battery. Most have very specific charging methods- most will not cope with normal lead acid chargers, will die if exposed to more than 15V, and can explode and catch fire. Try a later model smart charger for short (less than 10 minute) periods. I have a Motocell brand that is 7 or 8 years old, was in my TE250 before the 570, never required any more than a few minutes to bring back to 13.6V

Quality lithium like Shorai (LiFePo, not lithium you'd find in a mobile phone, computer or - uurrk - battery car or bike) have circuits which prevent overvolt charging and situations which can lead to disasters. But beware of lower quality LiFePo with inferior protection circuits. They do exist and accidents do happen, mainly with hoverboards, e-scooters and other suchlike products sold at unreal prices on dubious websites. Other than that you can use a non-specific charger, especially if the voltage has dropped below 8.5V where many smart chargers won't kick in. Think of it this way: Your bike can't tell the difference between a LiFePo and a normal Acid-Lead battery. If no safety mechanisms on a LiFePo, it could lead to all sorts of heartache. I have a Shorai on my Ducati 999S which is very hard to crank. 3 years, no problems starting after I got it.

I have this NOCO battery with 250 cca .Its a realy turbo battery for the starter.Very very nice battery.
