Black & Decker CD431K FS12 and CS1200K battery 12v cordless drill
Replacement Black-and-Decker CD431K FS12 and CS1200K battery pack, rechargeable 12v 2100mAh cordless drill batteries at low price

This range of Firestorm cordless drills and screwdrivers are often a basic in many a tool box, tough reliable power tools, they last a long time as long as they are cared for, much longer we suspect than many of the budget tools now available on the high street so its probably better to purchase a new battery for a known entity than a budget tool than will not last the course.

This compatible battery has 2100mAh or 2.1ah of storage energy, probably more than your original so it will be capable of more work on a single charge, we can also offer a 3.3ah version, more information on that will be found below.

Although this battery will not need any maintenance it will still need charging, do so when it arrives and first use, if you do not use it very often then before putting away and every 8-weeks, best advice is to use it often, they like to be used, do not however leave it on a charger for any longer than required to reach a full capacity charge

As stated above we can also offer a 3.3ah version of this battery to fit the Black-and-Decker CD431K FS12 and CS1200K, that's more that 50% extra holes drilled between charges, particularly useful if you are a heavy user or have a big project coming up, the link to this extended version can be found just a little bit further down the page, remember you can still use your existing original charger for both these options
