My Honda OE (made by JCI) battery went after ~6&1/2 years. I try to keep my batteries charged up on a maintainer semi regularly. I knew it was getting weak and starts were getting slower, quit when one day out and about. Luckily had a 5 year old Bestek 600A/10k mAh(rated) jump starter in trunk, fully charged. Worked like a champ. Tried to charge OE again later, got to charged, but quit again. Bestek worked again.
Checked prices online for 51R expecting to see WM Everstart Maxx (made by Clarios/JCI this area) best price, they were on markdown to $121 from $140. Then saw Sam's had a Duracell also (3 year full warranty) for $120, research showed made by East Penn. In my observation EP seems to be a Bitog favorite manufacturer, I know member bbhero is a big booster. Once I confirmed local Sam's had one and it was indeed EP made, made the purchase. $120 plus tax. These days, an excellent price. 51R is a relatively small battery and some complain about it. But I got 6+ years out of the OE, so I did not feel need to upsize and retro fit with required Honda parts.
All in all, satisfied with purchase and fact that first jump starter I ever purchased (~$40 Amazon) worked when needed.
