36 V 4 Ah Li-ion replacement battery

This Cameron & Co DS-CS-BST818PX pack delivers 36.0 V and 4000 mAh for Bosch 36 V cordless tools. It fits rotary hammers such as the GBH 36 V-EC and GBH 36 VF-Li, drill drivers including the GSB 36 V-LI and GSR 36 V-LI, and lawnmowers from the Rotak 32 LI to the Rotak 43 LI series.

36 V platform runtime limit

The 144 Wh capacity defines the practical runtime ceiling for any tool drawing from the 36 V rail. Heavy hammer drilling or sustained mowing will deplete the pack faster than lighter screw-driving, so users planning continuous high-load work should expect shorter intervals between charges.

Upgrade from 2 Ah or 3 Ah Bosch packs

Owners of older BAT818, BAT819, BAT836 or BAT837 batteries gain roughly double the ampere-hours with this 4 Ah unit, extending work time per charge. The jump is worthwhile when the tool sees frequent heavy use; occasional light-duty users may not notice the extra capacity.

Questions about this item

Should I choose the 4 Ah version or a lower-capacity pack for my Bosch 36 V tools?

This pack delivers 4 Ah at 36.0 V, providing 144 Wh of energy; select it when you need maximum runtime per charge, and choose a lower Ah pack only if weight or cost matter more than run time.

What does the 144 Wh rating mean when the battery is powering a GBH 36 V-EC rotary hammer?

At 36.0 V the 4 Ah cell stores 144 Wh, so the hammer draws from that reserve until depleted; actual minutes depend on the tool’s current draw and load profile.

Does the slide-style interface limit the current this 36 V 4 Ah pack can supply?

The pack mates with the Bosch 36 V slide mount used on models such as the GBH 36 V-EC and GSB 36 V-LI; the tool’s internal electronics govern the maximum current, not the battery contact design.
