It is fully-automatic with unique 8-step charging that supplies 4 A and which is suitable for standard charging of batteries between 8-100 Ah or for maintenance charging back-up systems up to 250 Ah.
MULTI XT 4000 analyses whether the battery can accept and retain the charge, it removes harmful lead sulphate crystals, charges quickly and efficiently and automatically switches to maintenance charging when the battery is fully charged. It has a practical Recond mode that balances the acid concentration in deep discharged batteries.

It is also fully compatible with vehicle electronics. It is also non-sparking and features reverse polarity and short circuit protection. MXT 4000 comes with a two year guarantee.
