    Capacity Advice

    A commonly asked question and our advice is generally to buy the biggest one you can afford, reason being is that the 575Wh battery will give you nearly 50% more range than the 375Wh battery and a 700Wh battery will double your range but most importantly the maximum power band is much longer on the two higher capacity batteries, helping you climb those steep hills on max power.

    The latest Wisper 700Wh batteries are installed with the very latest battery technology, these state-of-the-art batteries have advanced software that automatically assists in keeping a battery in perfect condition.

    A 575Wh battery will on average last one and a half to two times as long as the 375Wh battery and the 700Wh almost three times as long. This is due to the stress levels put on the battery being much lower on the larger battery.

    Wisper guarantees its batteries will not lose more than 30% of its capacity within two years of purchase. Consider that when a 575Wh battery has lost 30% of its capacity you still have a battery with a 400Wh, this will still offer assistance for longer than a brand new 375Wh battery, the same applies to the 700Wh battery after 2 years we guaranty you will still have just under 500Wh left.

    So, overall, a higher capacity battery is always cheaper but the critical point regarding battery longevity is that the battery is properly looked after, topped up regularly and never left flat for more than a few hours.
