    • In laboratory conditions over 1000 simulated charge cycles, the battery will retain at least 80% of its capacity.
    • The battery can be expect to lose 2-3% capacity per year through cell degradation, compared with a lead/acid battery which can lose 8-9% per year.
    • During testing of the battery with the Stewart Golf X-Series, its average use was 12-15Ah of the 22Ah battery per round of golf.

    We recommend that only an official Stewart Golf battery is used because other non purpose-made units may cause damage to your cart and will therefore void any warranty.

    User must charge battery with Stewart Golf charger to avoid the risk of damaging cells which will also void any warranty.
