Future Voltec battery will be smaller, die sooner
Instead, future products with the Voltech powertrain will use a battery that will be more easily replaceable than the current configuration, offered up in a variety of potential ranges. Savings will come from less complicated control systems meant to prolong cell life as well as improvements in energy density. Batteries in the first generation Chevy Volt have 16 kWhs of energy when new, but will only ever use half of that and will likely be extremely expensive to replace.
