Questionable reviews at best.
Bought battery Sat 7 March. Received email re purchase. Checked Mon Tues still being processed. Sent emails x3 no response. Which contradicts some of these good reviews. Wed started a process with PayPal. Thur 11 March response received refund being issued. So my guess is some if not all these reviews appear to be questionable. If they had have responded earlier to my messages then perhaps things would have been different. It’s a Chinese company with a base somewhere in UK.
