The Projecta HDBM4000 Battery Manager by Telwin is the ultimate in car battery charger technology, perfect for any sized professional workshop set-up. Charging amperage and voltage, as well as equalisation and desulphation programs are fully adjustable to allow a truly custom approach, but feature automatic pre-sets as well for added peace of mind. The inbuilt diagnostic process is able to identify faulty cells to avoid time and power wasted on batteries that will no longer accept charge, as well as alternator and starter motor testing functions to give you an overview of total system health and identification of potential non-battery related faults. For a helping hand during battery changes or charging you can activate the DC power supply mode, capable of maintaining a consistent system voltage to ensure that system memory is maintained while the battery is disconnected.
Suitable for 6V, 12V and 24V batteries this unit is capable of rejuvenating heavily sulphated and discharged batteries from as low as 2 Volts. The high intensity Engine Start function allows you to get a completely flat battery up and running again in as little as 5 minutes when you just need that single start. Compatible with most common battery chemistries, you know that you are ready for anything with the Projecta HDBM4000 Battery Manager
