I bought a Makita rechargeable battery. It would not fit on charger. They offered me an exchange but I didnt want another battery that wouldnt fit. The only way I could get a refund was to send it back to China. That would have cost me more than the battery was worth. I was left with buying a Makita brand battery anyway and out the original money. This was the company TopPower Inc. Bite the bullet and buy from a reputable company.
