Cameron & Co DS-CS-WB420MD for Welch-Allyn monitors

This lithium-ion replacement battery delivers 6.4 V and 6000 mAh for Welch-Allyn Spot Vital Signs monitors. It matches part number 105631 and fits the 4200B-E1, 420TB-E1, 42M0B-E1, 42MTB-E1, 42N0B-E1 and 42NTB-E1 models. The black pack measures 111.00 x 79.00 x 59.00 mm and weighs 38.40 Wh.

Sustained runtime on clinical carts

The 6 Ah cell maintains steady voltage through a full monitoring shift without the sag seen in aged packs. Internal resistance stays low so the monitor’s alarm and display functions remain responsive until the battery management circuit triggers shutdown. Recharge cycles follow standard lithium-ion profile with no memory effect.

Upgrades depleted OEM packs

This unit replaces an exhausted original battery that no longer holds charge for a complete patient round. It is not for users needing a second hot-swap pack or a higher-capacity chemistry than 6000 mAh. The jump is worth it when the monitor shows reduced uptime or unexpected shutdowns during routine use.
