Battery 18V 4.0Ah Li-Ion Spare

An 18V 4.0Ah Li-ion battery made for use with CT1646, CT3994 and CT3995 cordless tools. It gives you a direct replacement or backup battery pack for keeping compatible tools ready to use when the original pack is flat.

Useful for garage work, workshop tasks, fitting jobs and general DIY repairs, this spare battery helps reduce downtime when you are working through longer jobs. Keeping a second cordless tool battery charged can be handy for regular maintenance, home improvement work or trade use where stopping to recharge slows the job down. It also suits buyers replacing a worn pack to get an existing compatible tool back into service.

The 18V rating and 4.0Ah capacity make it suitable for users who want a battery with a good balance of cordless power and run time on the listed models. As a Li-ion battery, it is a practical option for repeated use with compatible tools and is straightforward to keep as a charged spare on the shelf, in the van or in the workshop. Compatibility is clearly limited to CT1646, CT3994 and CT3995, which helps buyers choose the correct replacement for the right tool. For anyone using these tools regularly, having a spare battery close to hand can help avoid unnecessary interruptions during routine work.
