Medical Depots Replacement for Welch Allyn 72200 3.5V Rechargeable Battery

Works perfectly.

Seems to be perfectly functional battery, no issues yet.

se debe mencionar que la pila llego sin carga y peor aún no funciona . se solicito el reclamo oportuno pero enviaron otra en similares condiciones total aqui tengo esa pila que no sirve de nada si ven este mensaje ojala me devuelvan el dinero.

I kept looking for a cheaper knockoff, but none of them worked well so I bought the name brand. Zero issues since. Hopefully it lasts a long time!

Works well. Affordable. Delivery went smooth Highly recommended.

Battery for an otoscope

This battery works with an older Welch Allyn otoscope 71050 plug in handle. Cannot say about longevity yet, but was pleased the light bulb came on with this battery.

A few important points for those seeking replacement WA batteries. First off most ads are misleading showing a WA battery but delivering a copy. Real WA batteries are made in Japan not China and are typically over $70 (although I've seen them for around $60 or so). Secondly, be sure to check the voltage as there are sellers who sell batteries that fit but with lower or higher voltage. Third check the contact clip found near the negative end of the battery. Its a manufacturing defect for the end of the clip (typically hidden under the wrap) to stick out. If it does your battery won't fit. Fourth, non-oem batteries typically have a shorter positive head than the WA ones. This may an issue with your particular device as the contact for the positive head (on the screw on piece) can vary in height a little bit, but enough so that its possible it may not make contact with the top of non-OEM batteries. This poor contact may result in the batteries overheating as you charge them. Having said all the above I still bought this non-oem battery because I couldn't stomach paying the WA price.
