In recond mode battery voltage 14.4 V.Not higher.

Is my charger faulty?

Hi @cmos, welcome to community!

The charger will only increase the voltage once the charge current has dropped to an acceptable level (ie. when the battery has been sufficiently charged to start reconditioning). See the manual for the actual levels.

Thanks,if i repeat a few cycles of charge,recond will work?

It might help yes. It depends on the size of the battery too.

I made already 5 cycles of charging and see no 16 V, only 14.4.

Charger 4amps. Battery bosch 45 Ah.

Don't know what to do((

The charger can only reach this voltage when the battery is so weak it can actually reach 16V with 4A
Just be happy it doesn't, it would be a battery in bad shape if id did.

But in manual :16 volts needs to equalise the cells.

And I know that for Ca/Ca batteries 16 volts needs for prevent acid stratification.

And I can't turn on this mode.

I will try discharge battery to 11.8-12 volts and will see what happens))
