    Starts a 4x4 3L Toyota Land-Cruiser diesel

    Posted by Ronen Hod on 27th Oct 2014

    I just received it last week, so I cannot testify for its long-term performance.
    However, I measured its CCA, and it gave me 350 out-of-the-box. Nice! They deliver as promissed, which is certainly not what I would say about my previous 8-cell-Ballistic that measured 140 instead of 275, and performed so-so for 2.5 years (now at 125 CCA).
    So I connected it to my 2001 4x4 3L Toyota Diesel, and although it was not as powerful as its native 800CCA battery, it managed to start it (I tried twice).
    Now my BMW F650GS Dakar starts beautifully. It fits well, and I tightened it using two cable-ties.
    The weight is higher than promissed 1250 gr. instead of 1080 gr.
