Frequently Asked Questions

What does Re-Celled mean?

Re-celling a battery pack is the process of replacing all of the depleted cells within a pack with brand-new, higher-capacity ones.

Re-celling battery packs is a cost-effective, eco-friendly way to extend the life of your existing battery pack. With our re-celled batteries, you'll get significantly more capacity than the original, with up to 33% more power available per charge. Re-celling also eliminates the need for frequent deep discharging, meaning you can use the battery without worrying about the memory effect. And finally, each re-cell battery pack comes with a one-year warranty, so you can rest assured that your new battery will perform as expected.

How does this work?

Our technicians begin by carefully opening the battery pack and replacing all the cells with top-quality components. We then use spot welding technology similar to what is used by OEM manufacturers to ensure each cell is securely connected.

Next, we check all wire leads and the motherboard for any imperfections. If any issues are found, we address them immediately before continuing with the rebuilding process.


Once everything has been checked and double-checked, our technicians adhere the battery pack back into its original form using extra-strength adhesive. Finally, they charge it entirely using an OEM charger so that when it arrives at your doorstep, it's ready to use! This entire process usually takes no more than one week from start to finish – meaning you won't have to go without your device for too long!

Will you repair my battery pack?

Yes! Our Bulldog Battery repair experts are master technicians, highly experienced and trained in the intricate process of rebuilding and repairing sealed lead acid battery packs. We use only the best quality tools and tech to ensure that each battery pack is carefully and accurately restored to its original state, with all necessary components replaced and functioning like new.

When do I get my battery back?

After the re-cell and repair, we will inspect your battery pack and charge it using an OEM charger so that the device is ready to use immediately! This entire process usually takes no more than one week from start to finish – meaning we guarantee you won't have to go without your device for too long!
