Bought a battery from Mr. Positive (online NZ battery store) for a UE Boombox BT speaker.
Within a week of receiving it, the battery regularly stopped accepting a charge and then failed completely some weeks later. Looks like a thermistor fault / short circuit.
After a bit of chasing up over months. Got a refund on the order. I feel this is way too long for redress.
(Noticed the product in question is now showing 1 in stock. It is genuinely hoped they didn’t simply put it back on the shelf to sell to the next customer…!)
