Robotina RB-GP12-12 Lead Acid Battery (AGM) 12Ah 12V

Mounted this battery on my kid electric ride car.After the first use, I charged the battery for 12 hours and it drained out after less than 2 mins.

They don't charge properly. Do not buy

We use this battery to inflate 2 queen size camping mattresses, and power a led light. There's enough power for several nights of camping without needed recharging.
