The Timesulin cap comes with a built-in battery, which is non-replaceable. Lifespan of a Timesulin is 12 months, the screen will start fading and then go blank. We will check up with you during your first months of Timesulin use to make sure you are satisfied and also remind you when it's time to replace your Timesulin unit.
There are a couple of reasons why we decided to make your Timesulin cap's battery non-replaceable:
The most important reason we require you to replace your Timesulin unit after approximately one year of use is:
- After clicking Timesulin on and off your insulin pens over the course of a year, the plastic inside the cap will have worn away slightly, causing the fit to not be perfect anymore. The last thing we want is for your Timesulin cap to fall off the insulin pen while in your handbag or briefcase.
It's mostly about safety, keeping Timesulin as light and lean and costs as low as possible. Some of the other reasons are :
- Adding a compartment with an opening and closing flap would have added bulk, weight and introduced the potential of the battery falling out of your Timesulin cap, causing the timer to fail. That would not have been safe.
- It would have made the product more expensive - and our goal was to keep costs as low as possible for users. Currently the cost is 7 pence / day. We believe that is a small price to pay for an easier and safer diabetes management.
- Timesulin lasts approximately 21x longer than your disposable insulin pen. After one year of use, the Timesulin cap will get dirty resulting in poor hygiene.
