Detail 01
1500 mAh capacity

SennheiserBA 2015 Accu Pack Rechargable Pack
1/2
Independent shopping perspective
The Korena take
Rechargeable NiMH pack for Sennheiser wireless bodypacks and handhelds that accept it. Buy it if you run wireless often enough that disposables add up.
Strong match
Who this is for
- Houses of worship or venues running wireless every week
- Anyone tired of buying AA alkalines by the box
- Rigs where a spare pack can swap between sets
Consider the trade-offs
When to look elsewhere
- Occasional users who run wireless a few times a year
- Sennheiser bodies that only take loose AA cells
- Anyone needing a spare at intermission with no charger
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
2 x 1.2 volt cells
2.4V total versus 3V from two alkalines. Transmitter battery meters read the lower voltage differently.
Detail 03
Drops into the battery compartment as one unit
No loose cells to fumble or insert backwards in a dark wing, and no polarity mistakes.
Detail 04
NiMH chemistry
Self-discharges while sitting. Top it off the day of the gig rather than a week ahead.
Detail 05
Sennheiser-specific pack shape
Fits the Sennheiser bodies designed around it. It is not a generic AA replacement for other brands.
Final check
Know before you order
- 01Charger is separate — confirm you have the matching Sennheiser charging base
- 02Check your transmitter model accepts this pack, not just AA cells
- 03Buy two if you play back-to-back sets with no charging window
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use regular AA batteries instead?
In transmitters that take AAs, yes. This pack exists so you stop buying them. It slots into the same compartment as one piece.
02How long does it run?
1500 mAh is in the same range as a good alkaline pair, so plan on a normal show length. Actual time depends on your transmitter's power draw.
03Does it come with a charger?
No. The pack is sold on its own and needs the matching Sennheiser charging base.
04Why does my battery meter read lower than with alkalines?
NiMH cells sit at 1.2V each versus 1.5V for alkaline. The meter is reading a genuinely lower voltage, not a faulty pack.
