What is the difference between a BatteryShip 100% OEM Compatible/Aftermarket battery and an OEM battery? has been selling quality 100% OEM compatible batteries and chargers since 2005. 100% OEM compatible means that they are aftermarket or generic batteries. Our generic batteries have been designed to not only fit and work in their respective devices but to also outperform the OEM version.

More Info:

Aftermarket – Our aftermarket batteries are brand new (NOT rebuilt, NOT remanufactured, NOT from old stock) and made by third party manufacturers. OEM is the abbreviation for Original Equipment Manufacturer (in other words, the original make/brand of the device). Our generic batteries fit and work in the respective devices they were made to fit.

The advantages of a BatteryShip 100% Compatible/Aftermarket Battery over an OEM battery are Price, Value, and Performance.

BatteryShip non-branded or generic aftermarket batteries offer customers a significantly lower price than that of the OEMs.

Value – In addition to lower price Aftermarket (Generic) Batteries offer consumers a greater value in terms of capacity and longevity. The higher the capacity rating, the longer your battery can last between charges (this is runtime). For example if an OEM battery has a capacity of 2.0Ah and the aftermarket version has a 3.0Ah capacity well then you are getting 50% more battery for your money.

The generic batteries at BatteryShip typically have an Ah rating 30-100% higher than the OEM batteries. Now that is some serious power!

More capacity equals more runtime. More runtime equals better value! Better value means more money you will save!

Performance - What is important to your device is that your voltage, capacity, chemistry meet the specific design needs of your tool. Your device does not care whether you have a big brand name on the battery or if it is a generic aftermarket battery! The key question to answer with regards to performance is will it work and how long will it last?

Aftermarket batteries are built to last! Aftermarket batteries that we carry use Grade A Quality cells and undergo the same quality testing practices that all other companies incorporate into their manufacturing processes. We utilize high quality battery cells that will last a very longtime - giving you day after day of great performance.

Our aftermarket batteries have a very low defect rate (running about 1% - which is great for any manufacture). Every manufacture and company has defects. It is a part of manufacturing regardless of the manufacturer’s name. Acceptable defect rates float between 1-3% of all units shipped. In manufacturing there is no such thing as 0% defect rate. That is why you have a product warranty with parts (money back periods and extended warranty periods).

Our warranty at is a 30 day Money Back Guarantee and a 1 Year Warranty against defects. This warranty guarantee protects your purchase.
