Its an over priced battery I am forced to buy. My last one lasted two years less than it was suppose to.

The E-04 is not a perfect gadget, but at least its easy to change the battery. The one I received in May 2021 appears to be quite fresh, the expiration is 4/26.

Easy, quick

all is fine

Easy to order online. Fast delivery. Hope I dont have to find out if it works!

Arrived promptly and in good condition.

Very happy with order and quick shopping

Bought the ELT years ago and was happy to see the battery was available quickly and not at an outrageous price.

Shipped fast and the battery was really new. Like about two weeks old. Impressive service.

Shipped fast. Easy installation. Worked as expected. Expiration date was a month less than the month we were on.

Battery was in stock and shipped quickly. Battery manufacture date was within three weeks of delivery to me which is outstanding. Changeout was a breeze. Highly recommended.

Works great, lasts a long time.

Surprised me by arriving exactly on the day first promised. Wish there was a short instruction sheet on how to install and orientation that needs to be maintained

Battery Delivered was Within 45 Days of Manufacture for Longer Expiration Period. ACK Needs to Mark Positive/Negative Poles Better on Unit.

Glen O Verified Purchase

ACK E-04 REPLACEMENT BATTERY

Battery already 5 month old. For the price we should have a full 5 years of use.

Fits. Pricey.

Good product, but was a little unhappy with getting a 7 month old battery. I needed it to fly and there was not another one available to exchange.

Happy with the purchase. My new battery was only 2 months old out of the box so it’s still good for 4 years and 10 months.

Would have gave 5 stars but ACK had a back order on these.(3 weeks) Not Aircraft Spruces fault.

The only problem I had with this order was not with aircraft Spruce but with ups who would not allow a pickup at there terminal which was only 10 minutes away

I fully appreciate that this product is hard to keep in a current month expiration status, but when I received my two batteries in January that had been made in November I wasnt really shipped a 5 year battery. Your comments would greatly be appreciated John

Like the ACK ELT, but hate the cost of this replacement battery. Seems like another case of stick it to the customer because he has no choice but to use our battery configuration.

I love Spruce overall and especially your speedy delivery. On this product I was surprised and disappointed that battery shelf life expires in Sep 2023. It is replacing a battery that never flew because aircraft is still under construction. I hope for first flight this year. I was under the impression battery was good for 5 years from manufacture or 1 st flight. I should have waited until closer to 1 st flight There were no instructions for disposal of old battery.

When you purchase battery I suggest speaking to aircraft spruce in advance to confirm the expiry date ... The battery I received was not 5 years - almost 5 months expired already - no price adjustment for the lapse (shipping back is not economical - due to cost) - the response provided we will send batteries with up to 75% of expiry date - my thoughts are - adjust price to reflect amount of time time expiry date - heads up !

Arrived with a manufacture date in Oct, so it is already 6 months old.
