This battery was a replacement for a solar charging unit that I use i a car. The old one 'expired' and grew fatter. Time will tell how well the new one will take and hold charge.

Ho preso questa batteria per sostituire una batteria di un strumento professionale. Le dimensioni sono un po’ più grandi dell’originale ma per fortuna c’è stata. Al momento dopo un mese poco più, sembra andare tutto bene. Grazie.
Its me.

It doesn’t have enough power to start my car so I’m thankful I didn’t buy this battery for that. (My car came with a battery that has lasted a while.) I bought this battery to power other things and it works great for that.
