• Hitachi WH6DC battery

When you receive your compatible battery, ensure you give it a reasonable charge. Using your battery a lot will help prolong its life span of it. If it's not being often used, then, do not put it away discharged and recharge it every six weeks to keep the cells fresh for later use.

It will take several charges and related use in your Hitachi WH6DC driver before it's able to take a full capacity charge. This is quite normal and part of the conditioning process that all batteries undergo to prepare the cells for their lifetime use.
