The document introduces the BK180 battery keeper, which automatically charges a car's battery in the background every time the ignition is turned on. It can prolong a car battery's life 1-5x compared to traditional jump starters. The battery keeper is fixed to the car battery and has built-in safety controls. It works reliably down to -25 degrees and is easy for all drivers to use, especially elders and women.

Battery Keeper

2. No help for battery.
Even jump starter works well, battery still need to be renew after the
indignation.
Complicated to use.
The engine hood need to be open, and battery positive and negative
side need to be connected correctly every using the jump starter. It is
too hard to use for ladies and elders.
Unsafe.
Sparks can be triggered during storage and use. It is unsafe especially
for ladies and elders.
Not reliable.
Jump starter battery need to be recharged on time. What frequently
happens is finding out there is low battery in the Jump starter when you
need it in a hurry.

every ignition
Prolong 1-5x life time of car battery,
even for new battery

Safety, Built-in MCU control, it still
safe even the positive and negative

Easy drive, no more battery concern,
especially for elders and ladies.

7. Battery Keeper automatic backstage operation at every ignition, user
don’t need to open the engine case to jump-start the car since MCU
automatically control the charging and engine start process
It can much better prolong the car battery life because battery output for
the engine start is much lower with the keeper’s help. Even when a dead
battery with voltage lower than 10V, it could still working well with the
help of battery keeper.
The battery keeper can be fixed firmly on the top of car battery with
cables and sticker.
About the safety, the Lithium titanate is the safest battery which is used
widely in electric car field, with MCU control current protection.
Water proof design with compact size: 150*84*44mm

8. Perfect solution for taxi
Battery Keeper is a perfect solution for taxi, because of the frequent
engine start daily, original car battery usually die quickly.

9. Installation
Location 1

10. System will start initialising when device is first connected to
battery. When both red and green LED flashing for 30 seconds
indicating system is in working mode.
Once ignition is detected system will discharge pulse current to
help the car starts. Green light will be on when device is working.
Battery keeper will be full charged during driving. Red light will be
on when charging and turns off when full charged.
