When I buy 3rd party batteries for my cameras I go Wasabi because I haven’t had problems with their batteries in the past even when Fujifilm cameras were no performing well with 3rd party batteries. Wasabi is releasing a NP-W235 battery on its own along with a stand-alone charger with 2 batteries and both are a bargain compared to the new Fujifilm NP-W235 price.
