BA 150, BA 151, BA 152 Rechargeable Battery Replacement Compatible with Sennheiser IR and RF Wireless Headsets (Compatible Models Listed in Description Below)

Easy to use

I purchased this for a set of wireless 'phones that were given to me, but, unfortunately, the headphones didn't deliver. Only one side worked and was barely audible at full volume.Battery was fine, however and I would recommend only if you have a set of Sennheiser 'phones.

The battery arrived promptly, was well packaged, it fit, and was already charged.

This BA151 unit charged well and lasted over 3 hours first time used. I’ll give an update if things change. However, if I were to do it again I would just order the two V80H batteries and replace them inside the plastic case, which opens easily enough. The original from Sennheiser years ago had name brand (Varta) batteries that still look brand new, and this Chinese replacement has no-name batteries that have some white oxidation (lose one star for that). Getting the name brand V80H replacements is also a lot less expensive.

I used up my third Sennheiser rechargeable battery for my ancient HDR 85 headphones so I thought I'd try this cheap compatible battery. It fits perfectly. No clue how long it will last, so far its working great. The Sennheiser batteries lasted a few years each.The original battery was listed as Battery Capacity: 70 mAh The new battery description says "Extended 80mAh " so maybe it holds more charge than the original. I can't tell the difference. The new battery holds a charge for longer than I'm willing to listen to headphones.

Best price for replacement battery in my Sennheizer wireless headphones.

so far they do not work at all.

Works great
